High accuracy temperature probes with excellent stability

sku Product SKU:  FCL-5640

Each temperature probe uses an ultra-stable glass thermistor enclosed in a thin-wall stainless steel tube. The basic semiconductor element is a bead of manganese, nickel, and cobalt oxides mounted on 0.1 mm platinum wires. For long-term stability, the thermistor is aged at various temperatures for 16 weeks. During the aging process, verification of the probe’s stability is done to ensure performance to published specs.

The 5640, 5641, and 5642 thermistor probes are designed for the temperature range of 0 °C to 60 °C. The 5643 and 5644 probes span the 0 °C to 100 °C temperature range. They offer stability of either ±0.002 °C or ±0.005 °C. These stability levels are guaranteed for one full year.

Precision calibration, traceable to NIST, is provided with each temperature probe. A computer-generated table in increments of 0.01 °C is furnished with each calibration based on the formula:

R=exp(A + B/T + C/T2 + D/T3)

The constants for the formula are obtained from a polynomial regression performed on the calibration data obtained. Over the range of 0 °C to 60 °C, calibration is performed at the triple point of water (0.01 °C) and 15 °C, 25 °C, 30 °C, 37 °C, 50 °C and 60 °C. For the 0 °C to 100 °C temperature range, the additional calibration points of 80 °C and 100 °C are used.

Each temperature probe is individually calibrated and includes a report of calibration from the manufacturer. Contact Fluke Calibration for calibration in our NVLAP accredited lab.

Thermistor standards are rugged, precision sensors suitable for use as secondary or working temperature standards for laboratory metrology applications. Because they generally are not affected by shock and vibration, you can use them in the most difficult field environments without worrying about calibration integrity.

Combine these probes with a 1560 Fluke Calibration Black Stack thermometer to read directly in °C, °F, or K. This combination gives you resolution of 0.0001 degrees and total system accuracy is better than ±0.004 °C.

Compare the cost of a 5640 calibrated temperature probe and a Black Stack thermometer to the cost of one uncalibrated SPRT. Between 0 °C and 100 °C, nothing beats the value of the 5640 Series Thermistors.

  • Accuracy to ± 0.001 °C
  • Affordable system accuracy to ± 0.004 °C or better
  • NIST-traceable calibration included from manufacturer; accredited calibration from Fluke Calibration optional

If you want a high-accuracy temperature probe with excellent stability at a great price, the Model 5640 series Thermistor Standards Probes give you all three in a great package. Why pay for an SPRT when you can get ±0.001 °C accuracy from 0 °C to 60 °C in a calibrated thermistor probe for about one-third the cost of an uncalibrated SPRT alone?

9118A Thermocouple Calibration Furnace

sku Product SKU:  FCL-9118A

Seven key features set the 9118A apart from other high-temperature calibration furnaces:

1. WIDE TEMPERATURE RANGE SPANNING MOST HIGH-TEMPERATURE APPLICATIONS

Standards and guidelines such as AMS 2750 and EURAMET cg-8 require that a thermocouple be calibrated over the full temperature range in which it is used. The 9118A temperature range of 300 °C to 1200 °C covers most high-temperature applications.

2. FLEXIBLE CONFIGURATION FOR CALIBRATING A WIDE RANGE OF THERMOCOUPLE TYPES

The 9118A furnace can be operated with or without an isothermal block, which increases calibration workload that can be performed with a single furnace:

  • Tube furnace configuration (without isothermal block): Base-metal thermocouples are often sheathed in formable materials such as braided fiberglass or PTFE. During calibration, they are bundled around a reference thermometer, held together with fiberglass cord or tape, and inserted into a tube furnace.
  • Isothermal block configuration: Metal- or ceramic-sheathed thermocouples are generally constructed with noble-metal thermoelements and therefore have higher calibration accuracy requirements. The isothermal block, which accommodates up to four 6.35 millimeter probes, improves heat transfer and temperature stability. This better equalizes the temperature between the reference probe and the UUT, which lowers measurement uncertainty compared to calibration without a block.

The furnace configuration can be quickly changed by selecting the calibration parameters stored in the controller for the desired configuration and inserting or removing the alumina ceramic isothermal block.

3. BEST-IN-CLASS TEMPERATURE STABILITY AND UNIFORMITY FOR CALIBRATION ACCURACY

Axial and radial uniformity, as well as constant temperature stability over time, are key factors that contribute to accurate thermocouple calibrations.

To minimize axial temperature gradients, three actively controlled heater zones compensate for temperature differentials between the central zone and the front and rear zones. Type-S thermocouples, which are less susceptible to drift than other types, are used for zone control and cutout. Axial temperature uniformity when using the isothermal block is ± 0.2 °C over a 60 mm (2.4 in) zone from full immersion at 1200 °C.

Radial (hole-to-hole) uniformity is ± 0.25 °C at 1200 °C when using the isothermal block, and ± 0.5 °C over a 14 mm (0.6 in) diameter at the center of the furnace tube without a block. 

When using the isothermal block, temperature stability is ± 0.1 °C or better over the full temperature range of the furnace.

 No other calibration furnace in its class comes close to this level of performance for both modes of operation. 

4. AUTOMATED SETPOINT CONTROL FOR IMPROVED LAB PRODUCTIVITY

A proprietary programmable controller, available in nine languages (English, Chinese, French, German, Japanese, Korean, Portuguese, Spanish, and Russian), enables technicians to automate setpoint temperature control for up to eight setpoint temperatures, the temperature ramp rate, and the time duration the furnace controls at each setpoint.

Automation and data collection can be further enhanced when the Fluke 1586A Super-DAQ is connected to the 9118A furnace through the RS-232 interface. The Super-DAQ can be programmed to control the furnace's setpoint temperatures and collect data for all sensors under test once the furnace has stabilized to within parameters defined by the user. After data has been collected at the first programmed temperature, the Super-DAQ will advance the furnace to the remaining programmed temperatures, collecting data at each setpoint. Once the test has been configured and started, the technician can walk away to work on other activities. 

5. NON-METALLIC BLOCK HELPS MINIMIZE THERMOCOUPLE CONTAMINATION

Calibration furnaces with metallic blocks can contaminate thermocouples, causing their accuracy to drift over time. To minimize the risk of contamination, the furnace well and isothermal block of the 9118A are constructed of non-metallic, ceramic alumina. This eliminates the need to protect the thermocouples under test with costly ceramic sleeving—reducing cost of ownership.

6. DEEP IMMERSION DEPTH TO SUPPORT MOST THERMOCOUPLE CALIBRATIONS

Industry standards such as AMS2750 recommend calibrating thermocouples at their normal working depth of insertion. The 9118A immersion depth is 365 mm (14.4 in) when using the isothermal block and 350 mm (13.8 in) to the central point of the furnace without a block. This immersion depth is adequate for most of thermocouple calibrations. The 40 mm x 700 mm (1.6 in x 27.6 in) open-ended furnace tube can also be useful when calibrating multi-junction thermocouples or when sample testing spools of thermocouple wire.

 7. DYNAMIC HEATER CONTROL AND CUTOUTS FOR RELIABILITY AND SAFETY

The 9118A controls the heater power level below 100% to prevent the heater elements from overheating—improving heater reliability and lifetime. Redundant over-temperature cutouts are built into the 9118A to ensure safe operation of the furnace. These include over-temperature, chassis thermostat, fan fault, control thermocouple fault, and user programmable cutouts.

PG7302 Piston Gauge

sku Product SKU:  FCL-PG7302

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.

4322 Automated Pressure Calibration System

sku Product SKU:  FCL-4322

4322 AUTOMATED PRESSURE CALIBRATION SYSTEM COMPONENTS

4322 PRESSURE CONTROLLER

The 4322 Pressure Controller is the primary component of the 4322 Automated Pressure Calibration System and is itself a highly capable calibrator. Very wide range measurement and control capabilities and advanced features are packed into one transportable, easy-to-use package.

SIMPLE, ACCURATE PRESSURE MEASUREMENTS

The 4322 Pressure Controller provides 0.1% of reading total one-year measurement uncertainty from low pressure to 10,000 psi (70 MPa). The simple yet accurate percent-of-reading measurement performance enables you to calibrate a wide range of workload with confidence that the test uncertainty radio (TUR) is adequate.

Four plug-and-play pressure measurement modules and a barometric pressure module are responsible for the pressure controller’s very wide measurement range. The 4322 switches module ranges automatically and seamlessly during use to utilize the best pressure module for each test point and operation mode.

All pressure modules store characterization and calibration information onboard and are interchangeable between systems to simplify calibration support and prevent downtime. Modules can be removed easily and replaced through the front panel with finger-tight fasteners.

Each 4322 Pressure Controller pressure measurement module features three redundant pressure sensors. The output of the three sensors is averaged automatically to reduce overall measurement uncertainty. The patented CalCheck feature automatically monitors and compares all three sensors to detect damage or out-of-tolerance conditions in the module, preventing potential measurement escapes before they can result in critical errors and costly recalls.

AUTOMATED PRESSURE GENERATION AND CONTROL

The 4322 Pressure Controller features automated pressure control from low absolute and negative gauge pressures to 10,000 psi (70 MPa). With breakthrough high-speed piezoresistive valve technology, the 4322 Pressure Controller can set and precisely control pressure to its highest range more quickly than even any other high-end benchtop or rack-mount controller available.

The pressure controller also features onboard automated vacuum and pressure generation and control, for calibrating devices from less than 1 inHg (0.5 psi, 3.5 kPa) absolute to 300 psi (2 MPa), without any external pressure or vacuum source. Patented pump-control technology enables the pressure controller to control faster, generate lower absolute pressure and control more precisely than other pump-based pressure calibrators.

The 4322 Pressure Controller offers adjustable control setting and multiple control modes to most efficiently meet the precision needs for the UUT being calibrated.

INTEGRATED CONTAMINATION PREVENTION SYSTEM

The 4322 Pressure Controller features an integrated contamination prevention system (CPS) to prevent contamination that can lead to costly downtime, damage and measurement errors. The CPS prevents liquid and particulate contamination from entering the pressure controller by maintaining unidirectional flow away from the controller. Upward pressure excursions are accomplished when the controller introduces clean supply gas into the test circuit through the CPS. Downward pressure excursions are accomplished through a purge solenoid valve located on the CPS, external to the pressure controller. Rather than being drawn into the controller, the gas and any liquid it has drawn out of the UUT are expelled through the CPS into a waste bottle for disposal.

As an extra level of protection against cross contamination of UUTs, Fluke Calibration designed the CPS to be modular and easily exchanged. You can remove and replace a CPS module from the 4322 Pressure Controller in just seconds and with only one hand. Color-coded CPS modules are available to separate “clean” from “dirty” service. You can open and clean the CPS assembly itself in just minutes without tools.

INTUITIVE USER INTERFACE

The 4322 Pressure Controller features rubberized direct function keys for common operations and a keypad for numerical entry. A rotary selection/jog wheel allows you to quickly increase and decrease pressure during a pressure calibration and navigate efficiently through the menus.

The advanced graphical user interface (GUI) makes it easy to review and edit calibrator settings; set up, store and execute test profiles; store results; and print calibration reports directly to any standard printer. The 4322 also features a full library of remote SCPI operation functions that you can access through USB 2.0 type B, IEEE 488.2 or RS-232 connections for full automation.

Despite being one of the most advanced, high-performance and feature-packed pressure calibrators available, the GUI makes the 4322 Pressure Controller remarkably easy to use. The “Normal” operating mode makes everyday calibration activities simple to perform, while the “Advanced” mode enables more experienced users to fully utilize the advanced features.

In “Normal Mode” operation, only necessary information is displayed as you are prompted through setup and execution of a calibration. The top half of the display consists of a window that clearly communicates pressure measurement and control values and settings. The bottom half of the display houses an instructional menu system that guides you step by step as you set up and execute pressure calibration sequences in an intuitive, linear workflow process. Calibration results with pass/fail criteria are displayed during the calibration and can be saved for electronic download at a later time. You can generate and send a calibration report directly to a standard printer via a USB connection on the pressure controller.

“Advanced Mode” allows you to control and measure pressure without stepping through a structured calibration sequence. Use this mode to access settings, data, and less-frequently needed information.

4322 PRESSURE INTENSIFIER

The 4322 Pressure Intensifier boosts supply gas from the N2 gas cylinder or other source of clean gas medium to as high as 10,500 psi for high-pressure calibrations.

The pressure intensifier employs a patented rotary cam design that drives four pistons to quickly generate the targeted output pressure. Because pressure is generated by four pistons operating in series with alternating compression cycles, the 4322 Pressure Intensifier produces smooth high-pressure output, instead of the significant pressure surges typical with traditional single-piston gas boosters.

The pressure intensifier is powered by a high-performance brushless servo motor drive with variable speed control, resulting in quiet operation that does not require facility-grade compressed air to drive it, or liquid lubrication.

To operate, simply select the target intensifier pressure from 1,000 to 10,000 psi (7 to 70 MPa) in 1,000 psi (7 MPa) increments by pushing the appropriate key on the pressure intensifier’s membrane keypad. The pressure intensifier controls the variable speed motor to generate and actively maintain the pressure supplied to the pressure controller.

The 4322 Pressure Intensifier generates pressure fast enough to keep pace with the 4322 Pressure Controller’s gas consumption during a typical calibration. On-demand pressure generation saves you from having to pre-charge a highpressure accumulator, thus reducing setup and operation time and improving safety.

4322 ACCESSORIES

Accessories enable you to optimize a 4322 Automated Pressure Calibration System for various applications.

HANDHELD REMOTE CONTROL PENDANT

Worksites do not always allow easy access to pressure measurement devices for calibration. The 4322 Handheld Remote Control Pendant enables you to calibrate even the most difficult-to-reach pressure devices while safely and effectively positioning both user and equipment.

The remote pendant is lightweight, compact and rugged. A rotary wheel, rubberized function keys and backlit graphical user interface mimic the controls and user interface on the 4322 Pressure Controller to allow one-handed pressure control and step-by-step execution of calibration sequences. The remote pendant features electrical switch test connections and test leads for fully automated pressure switch testing.

When combined with an optional 10 ft. (3 m) test hose, you can operate with agility in a tight or difficult workspace.

You might use the pendant to perform tasks like these:

  • Operate the calibrator while reading the output of the UUT at a remote terminal, or from an otherwise obstructed angle.
  • Set the calibrator on the floor or other stable surface while reading the output of the UUT at a different height.
  • Stand at a safe distance or behind a barrier when performing calibrations in a hazardous location.

PORTABLE COMPRESSED GAS CYLINDER ASSEMBLY

An optional portable compressed gas cylinder is available to supply gas to the 4322 Pressure Calibration System for operation above the maximum pressure controller pump pressure of 300 psi (2 MPa). The lightweight, aluminum cylinder features a shut-off valve with protective valve guard and a soft shoulder strap for portability.

The cylinder can be charged with up to 2,000 psi (14 MPa) supply gas for in-situ calibration. A removable self-venting regulator and high-pressure supply hose with quick-connection adaptors are included so you can quickly and safely connect the cylinder to the 4322 Pressure Controller or Pressure Intensifier.

Note: The 4322 Portable Gas Cylinder is certified according to United States Department of Transportation (USDOT) regulations. Use, refill and transportation of the gas cylinder may be subject to local regulation and/or prohibited from use in certain locations.

HIGH-PRESSURE FLEXIBLE HOSES AND ADAPTORS

The 4322 Automated Pressure Calibration System features test connection and hose options to further improve ease of use and safety.

High-pressure connections in the 4322 Automated Pressure Calibration System feature the Fluke Calibration IQC70 system. IQC70 adaptors are Interlocking quick-connect pressure fittings with working pressure of up to 10,000 psi (70 MPa). The male adaptor (stem) inserts easily into the female adaptor (coupler), where it snaps in and is held in place by retaining pins in the coupler. To disconnect, simply push a collar on the coupler, which releases the stem from the retaining pins. Applying pressure to the connection locks the collar and pins into place, preventing the stem and coupling from disconnecting until pressure is removed from the system.

The supply, output and test ports of the 4322 Pressure Controller, CPS and Pressure Intensifier are IQC70 couplers. IQC70 stem adaptors are available for various pressure connection types and sizes, allowing you to mount UUTs directly and easily to the 4322 Pressure Controller test port during calibration. The innovative IQC70 design allows the stem to rotate in the coupling even when pressurized, so you can position the UUT for best visibility.

Optional 10-foot (3 meter) test hoses are available to extend the test port if the UUT cannot mount directly to the pressure controller. The 4322 test hoses are rated to 10,000 psi (70 MPa) working pressure, yet are extremely light and flexible. A stainless steel braided sheath protects the durable high-pressure hose from accidental pinching or shearing. Test hoses are color-coded consistently with the CPS modules, so you can easily see the difference between “clean” and “dirty” service plumbing.

CONFIGURING A 4322 AUTOMATED PRESSURE CALIBRATION SYSTEM

4322 Automated Pressure Calibration System components can be combined in different configurations to meet a variety of needs for portability and performance.

4322 PRESSURE CONTROLLER UNIT ONLY

With only ac mains power, the unit delivers automated vacuum and pressure control and measurement from 0.5 psi (3.5 kPa) absolute to 300 psi (2 MPa).

4322 PRESSURE CONTROLLER WITH PORTABLE NITROGEN GAS CYLINDER ASSEMBLY

7050LP Low Pressure Indicator

sku Product SKU:  FCL-7050LP

The 7050LP low pressure digital pressure indicator, part of the versatile Series 7250 family, is specifically designed to meet the demanding performance requirements of calibrating low pressure sensors, transducers, mechanical gauges, portable calibrators and their plug-in modules. To accommodate bidirectional devices, the 7050LP can be supplied to operate in both positive and negative gauge modes.

The 7050LP offers unmatched performance and measurement precision. Utilizing multiple ranges in a single instrument, the 7050LP combines precision, stability, and affordability. The 7050LP has a unique quartz sensor, the most accurate pressure sensing technology available in a digital pressure calibrator. Each quartz sensor is manufactured and tested to provide the ultimate performance required by a Fluke Calibration pressure calibrator, ensuring that every customer receives the highest quality, precision and stability in their instrument.

Advanced precision

The 7050LP is available in three different range configurations, each a dual range instrument. Select either the 10 inH20 and 30 inH2O combination, or the 20 inH2O and 60 inH2O or the 35 inH2O and 100 inH2O range combination. Each combination provides a precision to 0.005 % of reading from 10 to 100 % of the higher range. For pressures from 0 to 10 %, the precision is a fixed error equal to 0.005 % of 10 % FS. This unmatched precision is achieved by the unique quartz pressure sensing technology that puts the pressure in direct contact with the quartz element, eliminating mechanical linkages and metal diaphragms. Since this is a differential sensor, the reference side of the 7050LP can be connected to the reference side (low side) of the device under test. Therefore, disturbances due to room drafts, HVAC systems and opening/closing doors, which can have a detrimental effect on the calibration process, are eliminated. The 7050LP provides both unequalled precision and excellent long term stability due to the inherent properties of quartz. For example, the total uncertainty for a 10/30 inH2O range combination over a one year calibration interval is 0.009 % of reading or 0.00015 inH2O (whichever is greater).

Automating pressure test and calibration

The 7050LP is easy to use and can be automated through the remote interface.

The 7050LP is provided with both an RS-232 and IEEE-488 interface, and syntax for all Series 7250s follows SCPI protocol for easy programming. COMPASS® for Pressure, an off-the-shelf software package, is available. A LabVIEW® driver is available as a free download. As a standard feature, software written for the previous generation Series 7215, 7010 and 6000 instruments is fully supported by the 7050LP. The 7050LP can be set to 510 emulation mode to use software originally written for the DPI 510. Firmware updates can be performed over the RS-232 interface (updates can be downloaded from the web site). A MET/CAL® software driver is available.

Versatility to handle any pneumatic pressure calibration

The 7050LP is versatile enough to handle almost any type of low pressure calibration.

Dual range: The 7050LP has two ranges in one instrument, 10 inH2O and 30 inH2O, or specify the 20 inH2O and 60 inH2O or the 35 inH2O and 100 inH2O range combination. The 7050LP will automatically change ranges to ensure the highest performance at the requested pressure.

Pressure units/scales: The 7050LP includes more than 12 standard units of measure, including inH2O at 4 °C (39 °F), 20 °C (68 °F), and 16°C (61 °F), in Hg at 0 °C (32 °F) and 16 °C (61 °F), kPa, bar, psi, kg/cm3, mm Hg at 0 °C (32 °F), cm Hg at 0 °C (32 °F), and cm H2O at 4°C (39 °F), and two user-defined units.

Head pressure: The 7050LP automatically corrects for head pressure differences.

Accredited Calibration Report: The 7050LP comes standard with an accredited calibration report.

Options

The 7050LP can be provided for gauge mode operation, or with:

  • Vacuum (negative gauge) mode for bidirectional devices
  • Rack mount kit
