molbloc-S Sonic nozzle calibration device

sku Product SKU:  FCL-molbloc-S

MOLBLOC-S RANGES

The mass flow rate through molbloc-S Sonic Nozzle is directly proportional to the upstream absolute pressure and independent of the downstream or differential pressure. molbloc-S flow ranges are defined by the molbloc's Pressure to Flow Conversion Ratio, KF. KF is expressed in units of sccm/kPa and defines the relationship between mass flow and the absolute upstream pressure delivered to the molbloc-S. molbloc-S calibrations are performed over flow ranges corresponding to either 20 to 200 kPa (3 to 30 psia), 50 to 500 kPa (7 to 70 psia) or 200 kPa to 2 MPa (30 to 300 psia) upstream pressure.

For flow measurements to be valid, the flow at the throat of the molbloc-S venturi nozzle must be critical, i.e. the gas speed is equal to the local speed of sound. Critical flow is achieved when a sufficiently low back pressure ratio, or BPR (molbloc-S downstream absolute pressure divided by upstream absolute pressure) is maintained. The upper limit of acceptable molbloc-S BPR values for critical flow varies between about 0.5 and 0.9 depending on the Reynolds number of the flow.

Since the mass flow through molbloc-S is proportional to the upstream absolute pressure, the flow range for this sonic nozzle calibration device in an application may be limited by the BPR limit. To maximize the range of a molbloc-S element, a vacuum pump can be connected downstream to reduce the downstream pressure while flowing. When the downstream pressure is kept sufficiently low, the upstream pressure, and thus the mass flow rate, can be adjusted all the way down to the minimum value for the molbloc's calibration type without being limited by the BPR. If molbloc-S will be used with atmospheric pressure downstream (no vacuum pump), then the molbloc can only be used over a range of upstream pressures starting at the maximum pressure for its calibration type down to a minimum pressure value at which the BPR becomes equal to the BPR limit at the current Reynolds number. molbox1 terminals include features to measure BPR, automatically alert the operator when the BPR is too high and prevent measurements when flow is not critical.

PG7202 High Pressure Gas Piston Gauge

sku Product SKU:  FCL-PG7202

PG7000 PISTON GAUGE LINE FEATURES REFERENCE LEVEL PRESSURE STANDARDS OFFERING A UNIFIED SOLUTION FROM VACUUM TO 500 MPA

  • State-of-the-art primary pressure standards for the lowest uncertainty levels
  • Unified solution from vacuum to 500 MPa
  • Outputs fully validated reference pressures in real time
  • Intuitive local operator interface
  • Manual, semi-automated and fully automated configurations

The PG7000 Series calibration standards are based on the fundamental principle of mass loaded onto a piston to apply a known force to a known effective area

Integrated piston-cylinder modules
Each PG7000 piston-cylinder is an integrated metrological assembly that includes the critical piston-cylinder mounting components. All of the mechanical parts that affect piston cylinder metrology are associated with the individual piston-cylinder, rather than being common parts of the piston gauge platform, enabling the user to:

  • Change ranges (piston-cylinders) in seconds, without using tools.
  • Handle and interchange piston-cylinders without exposing critical surfaces to contamination.
  • Protect the piston-cylinder from damage due to accidental shock or impact when handling.
  • Improve measurement reproducibility by avoiding frequent assembly/disassembly of mounting components.
  • Improve piston-cylinder mounting design by allowing each mounting system to be optimized for a piston-cylinder size and range.

 

Mass loading concentricity
The number of independent parts between the piston and mass load has been reduced to two—the piston cap and the mass loading bell. The piston head is effectively made part of the piston by machining it after installation concentrically to the piston within ± 20 microns.

Integrated electronics, software and remote interfacing
The electronics for monitoring all ambient and instrument conditions and functions are integrated into the PG7000 platform. RS-232 and IEEE 488 interfaces are included for remote communication. The system power supplies are also contained in the terminal to remove their heat source from the PG platform. For local operation, the user interacts with the PG7000 through a keypad and alphanumeric display on a compact terminal, allowing rapid, intuitive operation.

On-board measurement of operating conditions
PG7000 includes integrated on-board measurement of all the ambient and operating conditions needed to calculate pressure within tolerance, including relative humidity, barometric pressure, ambient temperature, piston-cylinder temperature, and reference vacuum.
Individual measurements can be observed in real time, both locally through the PG terminal and remotely over the RS-232 or IEEE 488 interface. Verification and recalibration of the on-board sensors is supported by embedded software.

Monitoring piston behavior
PG7000 measures and provides real time indication of piston position, drop rate, rotation rate, and rotation deceleration. Piston position is measured on the LVDT principle, with a ring on the inside of the mass loading bell acting as the armature. Rotation rate is measured optically by a sensor in the mounting post, which detects the movement of a notched ring on the inside of the mass loading bell. Both measurement systems are completely non-interfering, with no influence on the free movement of the piston in any axis.

Ready/not ready indication
The “ready/not ready indication provides the operator with a clear “go/no go indication of when an in-tolerance measurement can be made. It is based on testing for a variety of operating conditions, including piston position, piston fall rate, piston rotation rate, piston rotation deceleration, piston temperature rate of change and vacuum reference (when applicable). A ready condition is indicated when all conditions fall within specific limits. The limits for the various ready/not ready criteria can be customized by the user if desired.

Piston near-float detection
One of the most tedious aspects of operating a conventional piston gauge is adjusting pressure to float the piston. The piston lifts suddenly and without warning at the exact pressure corresponding to the mass loaded on the piston. Finding that point without overshooting requires slow and cautious pressure control.
PG7000 makes it easier to float the piston with a piston preloading system, which provides advance warning that the pressure is near the point where the piston will leave end of stroke. The preloading system only affects the piston when it is at end of stroke; it does not interfere with the free movement of the piston when it is floating.

Intelligent piston rotation
PG7000 is the first commercially available piston gauge to provide monitoring of rotation rate and decay in rotation rate. These measurements are used to assure that pressure readings are always made within limits. This relieves the operator of rotation rate monitoring responsibility and replaces subjective operator judgment with objective measurement.

Storage and shipping containers
The PG7000 piston gauge platform and mass set are packaged in heavy duty, weather proof, molded transit cases with custom inserts to provide optimum protection. PG7000 piston-cylinders modules are delivered in compact, virtually indestructible PVC bullet cases.

Advanced pressure generation and control components
All PG7000 pressure accessories are designed to increase the efficiency and ergonomics of piston gauge operation. These include manual, semi-automated and fully automated options to quickly and easily generate pressure and float the piston at the set point.

COMPASS® for Pressure calibration assistance software
COMPASS software sets up records for the units under test (UUT), defines and associates test procedures with UUTs, runs tests, acquires reference and test data, produces standard and custom calibration reports. All reference, UUT and test data is collected and stored in a database and standard delimited files. COMPASS can manage any kind of test from manual operator control and logging of test data to fully automated, unattended test execution.

A unified solution from vacuum to 500 MPa
The PG7000 line of piston gauges covers the complete range of pressure from very low absolute and differential in gas, up to 500 MPa (75 000 psi) in oil. While several piston gauge platforms and specialized accessories may be needed to cover different ranges and media, a consistent user interface and operational principles are maintained throughout the line. In most cases, complete gas and oil calibration capability can be achieved with just two PG platforms, four piston-cylinder modules and one mass set. Maintaining consistency from system to system makes them easier to learn and to use. Maintenance costs are reduced by minimizing the number of metrological elements to be supported.

PG7000 Piston Cylinder Modules
The piston-cylinder defines effective area and is the piston gauge's principal metrological element. The piston-cylinder's intrinsic characteristics and how it is mounted and exploited are the keys to piston gauge performance.

PG7000 piston-cylinders are manufactured by Fluke Calibration using proprietary production techniques that result in pistons and cylinders whose typical shape is within less than 0.2 micron from ideal geometry. Pure gas operated piston-cylinders use large diameters and very small annular gaps to minimize gas species and operating mode effects and to maximize piston float times. For example, the typical annular gap of a 35 mm gas operated piston-cylinder is less than 1 micron. Oil operated piston cylinders use small diameters to reduce the quantity of mass needed to cover the typical high pressure range.

All Type 7000 pistons and cylinders are made of tungsten carbide. Each PG7000 piston-cylinder is a complete, integrated metrological assembly that includes the critical piston-cylinder mounting components for improved metrological performance. All Type 7000 piston-cylinders use free deformation mounting systems in which the cylinder is allowed to deform under the influence of applied pressure, without O-rings or seals along the cylinder length. For higher pressure gas assemblies, a new mounting system, negative free deformation, applies the measured pressure uniformly along the full length of the cylinder. This reduces deformation under pressure, so piston drop rates remain low even at high operating pressures, while avoiding the unpredictable strain points of conventional reentrant designs.

PG7000 Mass Sets
Masses loaded on the piston are accelerated by gravity to apply a known force on the piston against which the defined pressure is balanced.

A PG7000 manual mass set is made up of main masses of 10 kg or 5 kg, fractionary masses in 5-2-2- 1 progression from 0.5 kg to 0.1 kg, and a trim mass set with masses from 50 kg to 0.01 g. Any desired mass value within the mass set range can be loaded to 0.01 g. All main and fractionary masses are machined from solid, nonmagnetic stainless steel and adjusted to their nominal values in the mass without cavities or trimming hardware which can reduce mass stability over time. Individual masses are comfortable to handle, with angled lifting surfaces on the edge of each mass and special mass trays that assist in orderly loading and unloading.

A PG7000 automated mass set is composed of main mass discs of 6.2 or 10 kg each and a set of tubular masses in binary progression from 0.1 to 3.2 or 6.4 kg. A pneumatically driven automated mass handling accessory (AMH) loads requested mass values in increments of 0.1 kg. The AMH and mass set are easily removed to access the piston-cylinder module when necessary.

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

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.

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

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.
