7050 Digital Pressure Indicators

sku Product SKU:  FCL-7050

The Series 7050 digital pressure indicator expands upon the popular line of Series 7000 products such as the Series 7250 digital pressure controller and Series 7252 dual output pressure controller. The 7050 provides an instrument for applications that only require pressure measurement.

Three models are available to meet a wide range of applications:

  • Model 7050i with advanced percent of reading precision
  • Model 7050 with a high performance-to-price ratio
  • Model 7050LP for low pressure measurements

The Model 7050i, 7050 and 7050LP all use a unique quartz sensor, the most accurate pressure sensing technology available. Each quartz sensor is manufactured and tested to provide the ultimate performance required by a Fluke Calibration pressure calibrator, ensuring that every customer receives quality, precision and long term stability in their instrument.

Standard precision

The Model 7050 offers an economical approach to high-accuracy pressure measurement, with a precision of 0.003 % of full scale. Various ranges from 0 to 5 to 0 to 1,500 psi (0 to 400 mbar to 0 to 100 bar) are available. For absolute mode operation, select either the barometric reference option, or the vacuum reference option, which requires an external vacuum pump connected to the reference port. The latter features an on-board vacuum sensor that allows automatic zeroing in absolute mode. Permanent absolute ranges to 50 psia (4 bar) are also available.

Long term stability

The Model 7050 not only provides unequalled precision, but also excellent long term stability of 0.0075 % of reading per year due to the inherent properties of quartz.

Automating pressure test and calibration

The7050 is provided with both an RS-232 and IEEE-488 interface, and Series 7050 syntax follows SCPI protocol for easy programming. As a standard feature, software written for previous generation Series 7215, 7010, 7000 and 6000 instruments is fully supported by the Series 7050. Intecal, an off-the-shelf software package is available. Firmware updates can be performed over the RS232 interface. A MET/CAL® driver is also available as an option.

Versatility

The Series 7050 is versatile enough to handle almost any type of pneumatic pressure measurement application.

Wide pressure range: available in a variety of standard or custom full scale pressure ranges from 10 inH2O to 1 500 psi (25 mbar to 100 bar)

Pressure units/scales: select from over twelve standard units of measure, including inHg at 0 °C and 60 °F, kPa, bar, psi, inH2O at 4 °C, 20 °C and 60 °F, kg/cm2, mmHg at 0°C, cmHg at 0 °C, and cmH2O at 4 °C, and two user defined units Head pressure: automatic correction for head pressure differences.

Absolute mode: The 7050 offers three different methods to make absolute pressure measurements. The barometric reference option provides the most convenient method and is available on ranges 15 psi (1.0 bar) and higher. Alternatively, the vacuum reference option allows the connection of an external vacuum pump to the reference port of the instrument. An on-board vacuum sensor monitors the reference vacuum and allows for automatic zeroing in absolute mode. This option provides the lowest overall uncertainty since it does not include the additional uncertainty of a secondary barometric reference sensor. For pressures to 50 psia (4 bar), permanent absolute models are also available.

Pressure limits: Set upper and lower pressure limits to sound an audible alarm. Automatic zeroing: All models feature automatic zeroing, including units with the vacuum reference option, for automated absolute mode zeroing through the front panel or over the PC interfaces.

Options

The following options are available for the Series 7050:

  • Vacuum (negative gauge) mode for bidirectional measurements
  • Barometric reference for absolute mode operation with the 7050i and 7050; ranges 15 psi (1.0 bar) and higher
  • Vacuum reference for absolute mode operation via an external vacuum pump connected to the reference port for 7050i and 7050
  • Permanent absolute ranges to 50 psia (4 bar) full scale, which include a tare feature for simulated gauge mode operation
  • NVLAP-accredited calibration report
  • Intecal software for Windows® The Series 7050 digital pressure indicators provide high performance pressure measurement with a wide variety of pressure ranges and options. All are

RPM4 Reference Pressure Monitor

sku Product SKU:  FCL-RPM4

RPM4 Reference Pressure Monitor is different from traditional pressure monitors. State-of-the-art performance from very low pressure to 280 MPa (40,000 psi)… advanced on-board features… compact and rugged… full local and remote communications… RPM4 is the perfect solution in a wide variety of high end pressure calibration, testing and measurement applications.

INFINITE RANGING™ AND AUTORANGE™

Infinite Ranging gives RPM4 Reference Pressure Monitor unprecedented versatility in adapting to the specific range of operation. With the easy-to-use AutoRange function, a few simple key strokes or a single remote command string at the start of a test adapt every feature of the pressure monitor to optimize it for the range to be covered. Just enter the maximum pressure and the measurement mode. AutoRange then:

  • Selects and activates the most appropriate Q-RPT to cover the specified range and measurement mode.
  • Sets the pressure unit of measure. • Activates absolute, gauge or compound gauge measurement.
  • Adjusts display resolution to the appropriate level for the range.
  • Adjusts overpressure alarms to the actual range of operation.
  • Reduces measurement uncertainty proportionally to the selected range (premium class Q-RPTs only).

Note: The use of RPM4’s Infinite Ranging and AutoRange feature is recommended to optimize operation for a specific range but is not required to obtain “% of reading measurement specifications.

SDS™ Q-RPT SELF DEFENSE SYSTEM

All Q-RPT modules up to 7 MPa (1 000 psi) include the unique Self Defense System™ (SDS). SDS valves automatically isolate and vent the module's Q-RPT when it is not in use or an overpressure is about to occur. With SDS, any Q-RPT module can be left connected to pressure up to 10 MPa (1 500 psi) without needing to isolate or disconnect it.

ADVANCED ON-BOARD FUNCTIONS

RPM4 pressure monitors provides a variety of advanced on-board pressure data functions including:

  • Special data such as pressure average over time, rate of change, hi/lo, freeze, deviation from set point.
  • Differential mode directly measures the difference between two Q-RPTs including taring at the line pressure.
  • Parallel measurement uses two Q-RPTs redundantly as one.
  • Leak check measures average pressure rate of change over a user set time period.
  • AutoTest automates calibration routines with tolerance testing and data logging.

QUARTZ REFERENCE PRESSURE TRANSDUCER (Q-RPT) MODULES

RPM4's outstanding pressure measurement specifications are made possible by Fluke Calibration’s exclusive quartz reference pressure transducer (Q-RPT) modules.

Q-RPTs measure pressure by measuring the change in the natural oscillating frequency of a quartz crystal with pressure induced stress. To be qualified for use in a Q-RPT module, each transducer is individually evaluated and characterized using primary pressure standards. Only transducers exhibiting required levels of linearity, repeatability and stability are selected. A proprietary compensation model, derived from more than 15 years experience with thousands of quartz pressure transducers, is applied to optimize the metrological characteristics needed in a transfer standard. Standard and premium class Q-RPT modules are available to best fit your performance and budgetary requirements.

A unique dynamic compensation for atmospheric pressure system uses an independent on-board barometer to provide seamless switching between absolute, gauge and compound gauge modes at any time. The barometer is used only to measure the small variations in atmospheric pressure that occur during gauge mode operation so its absolute error and drift over time do not contribute to measurement uncertainty. Q-RPT modules offer the advantages of:

  • % of reading measurement uncertainty with AutoRange span turndown available
  • Negligible warm up time
  • No gas species dependence
  • Quartz element isolated from test medium
  • Low sensitivity to orientation

Ametek Battery String Simulator (BSS)

sku Product SKU:  AME-Battery String Simulator (BSS)

The Elgar Battery String Simulators (BSS) provide safe, reliable battery power for spacecraft testing. The broad range of features available ensures simulation capabilities for more than just two terminal power. It's the ideal solution for complete integrated system testing, not just battery elimination.

The BSS behavior is determined by a charge table, in spreadsheet format, specific for a battery topology and various battery conditions. Many charge tables can be stored on the computer hard drive for easy retrieval.

The BSS operates in two modes, static and dynamic. In the static mode, when a state-of-charge value is entered, the BSS will instantly produce the terminal voltage corresponding to that state-of-charge. Because of this programmable flexibility, time consuming discharge cycles of flight test batteries are eliminated. In the dynamic mode, once a state-of- charge start point is entered, the BSS will monitor the charge and discharge energies being
impressed on the "battery" and modify the terminal voltage accordingly.

Single or dual battery pack simulator versions are available with discharge currents of up to 150A and charge currents of up to 50A per battery. In addition, optional sensor simulators (including thermistor, pressure transducer, and heater loads outputs) allow closed loop input to the Spacecraft Power Regulator for true battery emulation. As with the SAS systems, each Battery Simulator System is a fully integrated, turn-key system
using a Windows Graphical User Interface and hardware control software. This control is accomplished via a standard ethernet or optional GPIB interface using standard SCPI format commands.

The Sorensen SG Series (hereafter SG Series) represents the next generation of high power programmable DC power supplies. The SG Series is designed for exceptional load transient response, low noise and the highest power density in the industry. With a full 15 kW available down to 20VDC output in a 3U package the SG Series leads the industry in power density. The power density is enhanced by a stylish front air intake allowing supplies to be stacked without any required clearance between units.

At the heart of the SG series is a 5 kW power module. Depending on the output voltage, one to six modules can be configured in a single chassis to deliver 5 kW to 30 kW of power. Combinations of these chassis can then be easily paralleled to achieve power levels up to 150 kW. Paralleled units operate like one single supply providing total system current. Available in two control versions, the SGA has basic analog controls, while the SGI provides intelligent control features.

SGI: Advanced Intelligent Control 
(Sorensen General purpose Intelligent) The SGI combines onboard intelligent controls with the outstanding power electronics common to all SG family supplies. These controls enable sophisticated sequencing, constant power mode and save/recall of instrument settings. Looping of sequences makes the SGI ideal for repetitive testing. An impressive vacuum fluorescent graphical display in eight languages, context sensitive “soft” keys and front panel keyboard simplify programming of the SGI.

SGA: Outstanding Value - Analog Control 
(Sorensen General purpose Analog) The SGA, with its industry leading performance, is available for customers requiring simple front panel analog controls or external control. With the same high performance power electronics as the SGI, the SGA provides essential features like 10- turn potentiometers for setting voltage and current, 3 ½ digit LED readout plus front panel over-voltage protection (OVP) preview/adjustment and reset.

5616 Secondary Reference PRT

sku Product SKU:  FCL-5616

The temperature range of the 5616 covers –200 °C to 420 °C, and its high-purity platinum element and durability make it great for calibrating in the lab or in the field. When choosing a reference with a platinum element, there are two things you want to look at carefully: the short-term repeatability and the long-term drift. When PRTs are thermally cycled over their temperature range as they would be during a calibration, their resistance at the triple point of water can move up and down within an expected range. Fluke Calibration defines this range (called “short-term repeatability) as the repeatability at the triple point of water during three thermal cycles. 5616s are among the best performing in their class with short-term repeatability better than ± 0.010 °C (± 0.004 °C is typical). In addition, the 5616’s drift is ± 0.007 °C at the triple point of water when exposed up to its maximum temperature (420 °C) for 100 hours. These specifications are given at k=2 and therefore include a 95 % confidence level.

The 5616’s sealed ¬INCONEL® 600 sheath is 298 mm (11.75 in) long and 6.35 mm (0.250 in) in diameter. The probe’s PTFE-jacketed cable is made of silver plated copper that ends with four-wire leads, which eliminate the effects of lead-wire resistance on measurements. Use the 5616 with Fluke Calibration’s 1523/1524 Handheld Reference Thermometer1560 Black Stack1529 Chub-E4, or 1502A Tweener thermometer readouts.

Each sensor comes with a manufacturer’s report of calibration. The report includes the expanded uncertainty (k=2) at seven calibration temperature points, ITS-90 calibration coefficients, and a temperature vs. resistance table presented in 1 °C increments. Compare the 5616 to other Secondary Reference PRTs. You’ll like its price, but you’ll love its performance.

2413 DPI Cell

sku Product SKU:  FCL-2413

Fluke Calibration’s differential pressure cell and null indicators are designed to separate two media physically while only contributing five parts per million uncertainty to the measurement process. 

The differential pressure cell has two pressure chambers separated by a thin metal diaphragm. A difference in pressure in the two chambers causes a deflection of the diaphragm which is sensed by an LVDT circuit. The output from the LVDT is displayed on the indicator. 

The differential pressure cell and indicator is capable of indicating when zero differential pressure exists between two systems to within five parts per million. However, it is not intended to measure the magnitude of a differential pressure. 

Approved gas media in either chamber include dry air, nitrogen, CO2, and the noble gases and exclude hydrogen and oxygen. Liquid media in the top chamber may be virtually any nonconducting, noncorrosive liquid. Liquid media in the lower chamber can be virtually any noncorrosive media. For applications where water will be used in the lower chamber, Fluke Calibration offers a differential pressure cell manufactured from monel. 

A variety of configurations can be provided, including a differential pressure cell equipped with a constant volume valve for deadweight gauge crossfloat calibrations. 

A zero offset correction curve is supplied with all differential pressure cells and indicators, except those equipped with a constant volume valve since the differential pressure cell is re-zeroed at each pressure during a crossfloat calibration. This curve is a one-time process and the differential pressure cell and indicator do not require periodic testing or calibration. 

During manufacture, all testing of the differential pressure cell is performed with nitrogen; therefore the instrument is supplied with each chamber dry. Once the user has committed either chamber with a liquid, changing that chamber to a different liquid is not recommended as it requires disassembly, cleaning and replacement of the diaphragm. This procedure should only be performed at the factory, and requires a new zero offset correction curve.

  • High performance, low cost
  • Diaphragm isolation provides physical separation between different media
  • Maximum error contribution of 5 PPM
  • Model 2413 is for pressures to 15,000 psi
  • Compatible with virtually any non-corrosive gas or liquid media
  • Time saving tool for cross float calibrations

Ametek ETS TerraSAS

sku Product SKU:  AME-ETS TERRASAS

For microgrids, energy storage, and inverter test applications, the TerraSAS™ series photovoltaic (PV) simulators are specifically designed to emulate the dynamic electrical behavior of a terrestrial PV solar array. They offer low output capacitance and high closed loop bandwidth to keep up with the advanced Maximum Power Point Tracking (MPPT) algorithms used in today’s grid-tied inverters. The Embedded TerraSAS (ETS) is a high performance solution in a small form factor that combines an agile power supply with an innovative I-V curve generator in a single standalone unit.

• ETS 600 / 1000: For isolated and non-isolated string inverters up to 1000Vdc Voc.

• ETS 60 / 80 / 150: For use with micro-inverters or DC optimizers up to 150Vdc Voc.

• See Datasheet under Downloads: Datasheet

Application
Many solar inverters generate AC ripple on their DC input, which is connected to the photovoltaic array. For single phase inverters, the frequency of this ripple is twice the line frequency (120 Hz for US models). The simulator’s power supplies must not suppress this ripple as a function of their regulation loop. An increasing number of inverters (and virtually all micro-inverters) accurately measure amplitude and phase of the ripple voltage and current to quickly track the MPP of the array. This approach allows tracking the MPP at a much higher speed when compared to conventional dithering techniques (also called perturbate-and-observe). Faster tracking of the MPP results in a much higher overall efficiency in cloudy conditions, where the irradiance is constantly changing. It is likely that all solar inverters will use this approach in the near future, since end users are very sensitive to the overall efficiency of their solar energy installations. To satisfy this requirement, the PV simulator must be capable of reproducing the voltage / current behavior of a solar array at the ripple frequency. Most standard switching power supplies employ very large output capacitors and inductors in their output circuits and are unable to deliver the required performance - regardless of the response speed of the I-V curve controller. The Elgar TerraSAS line of PV simulators are based on high speed versions of our standard products, where output capacitors and other speed-limiting components have been adjusted. This results in a speed improvement of 10 times or better. Proprietary features built into the PV controller hardware and firmware, combined with our high speed power supplies, deliver the required performance. This technology was extensively tested on micro-inverters and is ready to test the next generation of inverters. The required performance is delivered by high speed switching power supplies and advanced Digital Signal Processing techniques. In some conditions traditional DC power sources using IGBT technology do not meet MPPT response speed requirements, depending on the MPPT principles. Our power supplies use Power MOSFETs, which typically switch ten times as fast as the most recent IGBTs. Higher switching frequency translates to smaller output capacitors and inductors - which is the key to a successful high speed power supply design.

Scalability
Power supplies are available in 850W, 5kW, 10kW, and 15KW increments. The 80V units are available in two power levels: 1200W for microinverters and 850W for the latest generation microinverters and DC power optimizers. The bandwidth on the 850W version has been improved to 30kHz by adding a linear regulation output stage. 600V and 1000V units are available in 5kW, 10kW, and 15kW versions depending on Isc requirements. All versions are easily connected in parallel to scale output power up to handle microinverters, string inverters, and even utility scale inverters. Many models can also be connected in series to handle higher voltage tests. Please refer to the connection diagrams located in the User Manual and follow appropriate wiring codes before connecting ETS PV simulators in series or paralle.

PG9602 Piston Gauge

sku Product SKU:  FCL-PG9602

INNOVATIONS TO MINIMIZE UNCERTAINTY

Two decades ago, DH Instruments PG7000 family of piston gauges introduced the advantages of on-board sensing and monitoring technology, as well as other performance and ergonomic enhancements. The PG9000 platform adds several innovations to improve pressure measurements even further.

The platform consists of a piston gauge base, terminal and new remote electronics module. The terminal is the user interface. It stores metrological component data, reports operating and ambient condition status and calculates pressure.

The PG9000 piston gauge base supports automatic piston-cylinder rotation and mass handling, but all of the electronics to support the sensors and rotation control have been relocated to a remote electronics module. This architecture supports the best possible temperature stability at the base, even with prolonged vacuum operation, since any significant sources of heat are located away from the base.

The PG9602 mounting post has two integrated PRTs for reduced piston-cylinder temperature uncertainty. The PRTs are easily removed for calibration. A capacitance diaphragm gauge is included in the optional vacuum reference hardware for making residual vacuum measurements in absolute mode. PG9602 can also integrate the measurement output from virtually any user-supplied vacuum sensor.

METROLOGY SUPPORTED BY AUTOMATION

AMH automated mass handling technology is expanded on PG9602 to provide gauge and absolute operation with up to a 100 kg mass load. Eliminating manual mass loading minimizes mechanical wear, improving mass stability. The automated mass handler operates inside the evacuated bell jar, so the time to release and draw a vacuum while changing masses between test points is eliminated. The sustained vacuum produces lower and more static residual vacuum values. Total test time and productivity are greatly improved, especially on absolute pressure tests. More importantly, full automation promotes highly consistent measurements and allows extensive tests with many test points that would be impractical to perform manually. And with the help of calibration management software like COMPASS® for Pressure, tests can be run fully unattended.

2468A - Pitot/Static Primary Standard

sku Product SKU:  FCL-2468A

The Model 2468 Pitot Static Primary Standard is specifically designed for calibrating today’s high performance flight line and Air Data Test Systems. With the new autofloat controller, operator intervention is reduced to simply applying the mass load indicated by WinPrompt® software. WinPrompt applies all required correction factors, real time, to insure attainment of the highest level of performance available in a gas piston gauge which is required to calibrate today’s RVSM compliant test sets. The Model 2468 is based on the popular Model 2465 Gas Piston Gauge which has a long history of serving national standards laboratories, commercial industry and government organizations as a primary pressure standard for over 40 years. Time-proven materials, hand craftsmanship, and a lineage of intercomparisons to national standards laboratories at the highest levels are coupled with new automated technology to make the Model 2468 Pitot Static Primary Standard the world’s choice for calibrating Air Data Test Systems.

Automating the standard

The autofloat controller communicates through an RS-232C interface with WinPrompt software, a powerful Windows based calibration management program. WinPrompt automates all the functions required to perform an accurate calibration with ease. Since it is a Windows based application, it can communicate through the Dynamic Data Exchange (DDE) function with other Windows applications such as a word processor to provide customized calibration reports and spreadsheet applications to perform graphical or numerical analysis.

The process begins by creating a procedure file with the sequence of altitude or airspeeds required to calibrate a particular Pitot Static Tester. Although these instruments typically display altitude in feet and airspeed in knots, they usually require calibration in linear pressure units such as in.Hg or mbar. WinPrompt allows the procedure file to be setup in avionics units such as feet, meters, knots or pressure units such as inHg, mbar, kPa and many others. Once the procedure file has been created and saved, it can be recalled whenever the particular test set requires calibration, therefore minimizing setup time.

For each point to be generated, WinPrompt provides the operator with a list of masses (each individual mass is engraved with a unique sequence number) to apply to the top of the piston. The operator has the option of using trim masses supplied to generate an exact value, or accept the nominal value using only the main mass set.

With the first point selected, the operator uses the mouse to select the autofloat icon on the menu bar. The software then prompts the user to verify that the required masses have been applied. Upon confirmation by the user, the autofloat controller generates the requested pressure to the point where the piston is “floating”.

Once the pressure is established, the autofloat controller monitors all system parameters and updates the actual generated pressure, real-time. With a stable float position obtained, the status bar at the bottom of the screen changes from red to green indicating that the reading or adjustment of the device under test can be made. The device under test reading can be entered along with any particular comments in a separate text field. WinPrompt records this information along with the actual pressure generated by the Model 2468. The operator then proceeds through each step until all pressure points in the procedure file have been generated. Once the calibration procedure is complete, the calibration file can be saved with a unique file name and a calibration report can be printed. Since WinPrompt supports the Windows Dynamic Data Exchange (DDE) function of Windows, all information can be exported to a spreadsheet program to perform mathematical and graphical functions and/ or a word processing program for customized calibration report documents.

Piston/cylinder assemblies

For calibrating most Pitot Static Test Sets, only the standard piston/cylinder supplied is required. The standard piston/cylinder generates pressures from 1.4 to 103 inHg in autofloat mode and from 0.4 to 103 inHg using a manual pressure adjuster. This provides an effective altitude range from -610 to 19,812 meters (-2,000 to 65,000 feet) feet in autofloat mode -610 to 27,432 meters (-2,000 to 90,000 feet) using a manual adjuster) and airspeeds over 1,000 knots. An optional piston/cylinder is available for generating pressures from 3.4 to 400 inHg allowing calibration of other pressure related devices, such as pressure transducers.

Both the standard and optional piston/ cylinder assemblies are manufactured from proven materials that have evidenced superior strength, durability, low distortion, low thermal coefficients and virtually undetectable hysteresis over the last several decades, and have an unparalleled record of long-term stability. Each piston/cylinder installs quickly into the pressure column without the need for special tools. Piston/cylinder assembly change-out can be completed in less than one minute.

Mass set

The Model 2468 is provided with a single mass set that is used with either the standard or optional piston/cylinder. Each mass is engraved with a unique sequence number and a common serial number. A storage case is supplied which allows storage of the mass set and one or both piston/cylinders. Each mass is machined to a nominal value and is made from nonmagnetic materials to provide long-term stability and eliminate sensitivity to magnetic fields. For ease of use, the entire mass set totals just 12 kilograms (26.40 pounds), with a maximum platter mass of 1 kilogram (2.2 pounds). A laboratory grade trim mass set is included to allow any pressure increment within the range and resolution of the piston/cylinder assembly.

Instrument base

The instrument base is designed with functionality, economy and space conservation in mind. All electronic components are housed away from the instrument base to eliminate errors caused by thermal effects and magnetic fields. The thermally isolated motor drive is connected to the cylinder—eliminating pressure fluctuations and maximizing productivity. A durable, acrylic bell jar is provided to allow absolute mode operation when calibrating altitude and other absolute reference devices. A KF16 fitting is provided to simplify installation and allow low reference pressures

Vacuum pumps

In order to operate over the entire altitude and airspeed range, two vacuum pumps are required. One pump is connected to the reference port of the Model 2468 using a KF16 connection. This allows the area inside the bell jar to be evacuated which is required for altitude calibrations (absolute mode). A second vacuum pump is connected to the autofloat controller which allows automatic control of pressures down to 1.4 inHg absolute. In order to generate positive pressures, a regulated gas supply (clean dry air, or nitrogen) must be supplied to the autofloat controller. Fluke Calibration can supply vacuum pumps which are rated to the appropriate vacuum capacity and include an auto-vent valve and backstream filter for contamination prevention along with a muffler for quiet operation.

Connecting lines and fittings

Fluke Calibration can provide an optional lines and fittings kit which includes all interconnecting tubing for pressure and vacuum supplies along with all required cables and adapters.

Barometric reference

The Model 2468 equipped with the autofloat controller is provided with a barometric reference sensor to allow system operation in absolute mode and also simulated absolute mode where establishing the bell jar vacuum (reference vacuum) is not required.

Computer

The autofloat system requires a standard desktop or notebook computer for operation. A Pentium level processor, RS-232 interface and Windows 95/98 are the only requirements. The computer can be supplied by the customer or Fluke Calibration can provide an optional notebook computer with the system which is pre-loaded with Windows 95 or higher and WinPrompt software.

Manual configuration

Fluke Calibration also offers a manually operated pressure control system for setting the pressure and float position. This configuration can also be used with WinPrompt software and the Model 2456 Deadweight Gauge Monitor. The Model 2456 continuously monitors piston temperature, float position, and sink rate, and optionally air density and reference vacuum. WinPrompt calculates mass-to-pressure and pressure-to-mass values, and when used with the Model 2456, automatically reads and displays real-time piston gauge parameters. A separate brochure is available that covers the Model 2456 Deadweight Gauge Monitor.

1529 Chub-E4 Standards Thermometer

sku Product SKU:  FCL-1529

The Chub-E4 has four inputs for reading four different sensors simultaneously, and we’ll configure those inputs in any of three different ways according to your preference. Choose four channels of thermocouple inputs, four channels of PRT/thermistor inputs, or two channels of each. With this thermometer, reading thermocouples, PRTs, and thermistors accurately from the same device is no problem.

100-ohm, 25-ohm, or 10-ohm PRTs and RTDs are read using ITS-90, IEC-751 (DIN), or Callendar-Van Dusen conversion methods. Typical accuracies include ±0.004 °C at –100 °C and ±0.009 °C at 100 °C. Thermistor readings are converted using the Steinhart-Hart polynomial or standard YSI-400 curve and are as accurate as ±0.0025 °C at 25 °C with resolution of 0.0001 °.

Thermocouple inputs read all the common thermocouple types, including B, E, J, K, N, R, S, T, and Au-Pt, and allow you to choose between internal and external reference junction compensation. Typical accuracy for a type J thermocouple at 600 °C is ±0.35 °C using internal reference junction compensation and not including the thermocouple. (Support for C and U type thermocouples is available. Download the application note Using Fluke Calibration Readouts with Tungsten-Rhenium and other Thermocouples.)

PRTs and thermistors connect easily to the 1529 using Fluke Calibration’s patented mini DWF connectors, which accept bare wire, spade lug, or mini banana plug terminations. Thermocouples connect using standard or miniature terminations. Measurements are taken each second and can be taken simultaneously or sequentially. A special high-speed mode allows measurements on one channel to be taken at the rate of 10 per second.

DISPLAY

If you think three sensor types and four inputs sounds versatile, wait until you see the display panel on the Chub-E4. Displaying measurements in °C, °F, K, ohms, or millivolts and choosing temperature resolution from 0.01 to 0.0001 are just the beginning.

You can also select any eight items from our long list of displayable data fields to view on-screen. Choose statistical functions such as averages, standard deviations, and spreads; choose probe information such as probe type and serial number; choose T1–T2 functions using inputs from any two channels; or choose utility functions such as the date, time, and battery power level. You can even save up to 10 screen configurations for easy recall.

The push of a single front-panel button also brings up a simple menu system to easily guide you through all the internal setup and memory options of the 1529. Probe coefficients, sample intervals, communication settings, password settings, and a host of other functions are all easily accessible.

COMMUNICATIONS

The memory and communications capabilities of the Chub-E4 make it perfect for benchtop thermometry, on-site measurements, lab calibration work, and remote data logging. Optional software packages from Fluke make this one of the most powerful thermometers on the market.

With battery power and memory to store up to 8,000 measurements (including date and time stamps) at user-selected intervals, the 1529 has plenty of data logging capability. Store 100 individual measurements or any number of automatic log sessions (up to 8,000 readings), each tagged with an identifying session label. Fourteen different logging intervals may be selected, from 0.1 second to 60 minutes.

With Fluke Calibration’s 9935 LogWare II (page 85), data may be quickly downloaded to your PC for complete graphical and statistical analysis. Separate log sessions may even be automatically downloaded to separate files based on session labels. With this software, the 1529 can even be used for real-time data logging. Log four channels at once directly to your PC with virtually no limit to the number of data points you take. You can analyze data, set alarm events, and even set delayed start and stop times.

With MET/TEMP II software, the Chub-E4 may be integrated into a completely automated calibration system. Use one input for your reference thermometer and calibrate up to three other thermometers automatically (see page 81). An RS-232 port is standard on every unit. An IEEE-488 port is optional.

MORE GREAT FEATURES

Did we forget some aspect of versatility on this thermometer? No!

The 1529 runs on AC power from 100 to 240 volts, DC power from 12 to 16 volts, or off its internal nickel-metal-hydride battery for eight hours between charging. The standard battery charges in less than three hours and lasts through 500 charge/recharge cycles.

If you want to rack-mount your Chub-E4, we’ve even got a rack-mount kit for you. This unit fits on your benchtop, in your instrument rack, and even in your hand.

Of course, all the reference thermometers you might need for your 1529 are available from Fluke, including secondary standard PRTs, standard thermistors, and noble-metal thermocouples. Carrying cases and even a serial printer for direct printer output are also available.

We’ve said it before and we’ll keep saying it: Fluke Calibration simply makes the best thermometer readouts in the world. No one else gives you a comparable combination of accuracy, versatility, productivity-enhancing features, and price. No one. Get a Chub-E4 and just enjoy everything it’ll do for you. You’ll love it.

Microchip Technology 5125A

sku Product SKU:  MIC-5125A

The Microchip Technology 5125A makes accurate phase-noise measurements on signals from 1 MHz to 400 MHz, covering the full range of the most commonly used frequency references. The Microchip Technology 5125A, which requires absolutely no configuration, displays measurement results seconds after the Start button is pressed.

Overview

Microchip Technology's 5125A makes accurate phase-noise measurements on signals from 1 MHz to 400 MHz, covering the full range of the most commonly used frequency references. The Microchip Technology 5125A, which requires absolutely no configuration, displays measurement results seconds after the Start button is pressed.

Over 25 years of research at the National Institute of Standards and Technology (NIST) and in private industry have come to fruition in Microchip Technology''s phase noise test sets, which employ both direct sampling of the RF waveforms as well as cross correlation, making it possible to easily characterize the highest performance time and frequency references. The third generation, all-digital 5125A has been designed to meet the most demanding requirements. The Microchip Technology 5125A can measure phase noise down to -145 dBc/Hz at 1 Hz offset from a 10 MHz carrier and -130 dBc/Hz at 1 Hz offset from a 100 MHz carrier, making it the perfect solution to characterize the very low noise frequency references, such as those used in RADAR and satellite communications.

The all-digital architecture employed in the 5125A uses advanced, high-speed, low-noise analog-to-digital converters in a patented architecture that does not require a phase-lock loop to make measurements. This provides multiple benefits for 5125A users:

  • Measurements are extremely easy to make, with no pre-calibration or configuration required.
  • Accurate results are presented within seconds of a measurement having been started.
  • Input carrier signals can be characterized much more accurately than before, to within 0.1 mHz of the carrier.
  • The stability or Allan deviation is measured in parallel with phase noise. The 5125A also includes a frequency counter with 13 digits of precision.
