Product Information

Mid Temp Field Metrology Well, 33 °C to 350 °C, with 9143-INSF and Process Electronics

Small dry wells for big field applications
The new 914X Series Field Metrology Wells extend high performance to the industrial process environment by maximizing portability, speed, and functionality with little compromise to metrology performance.

Field Metrology Wells are packed with functionality and are remarkably easy to use. They are lightweight, small, and quick to reach temperature set points, yet they are stable, uniform, and accurate. These industrial temperature loop calibrators are perfect for performing transmitter loop calibrations, comparison calibrations, or simple checks of thermocouple sensors. With the “process” option, there is no need to carry additional tools into the field. This optional built-in two-channel readout reads resistance, voltage, and 4–20 mA current with 24 volt loop power. It also has on-board automation and documentation. Combined, the three models (9142, 9143, and 9144—each with a “process” option) cover the wide range of –25 °C to 660 °C.

High performance for the industrial environment
Field Metrology Wells are designed for the industrial process environment. They weigh less than 8.2 kg (18 lb) and have a small footprint, which makes them easy to transport. Optimized for speed, Field Metrology Wells cool to –25 °C in 15 minutes and heat to 660 °C in 15 minutes.

Field environment conditions are typically unstable, having wide temperature variations. Each Field Metrology Well has a built-in gradient-temperature compensation (patent pending) that adjusts control characteristics to ensure stable performance in unstable environments. In fact, all specifications are guaranteed over the environmental range of 13 °C to 33 °C.

Built-in features to address large workloads and common applications
Whether you need to calibrate 4-20 mA transmitters or a simple thermostatic switch, a Field Metrology Well is the right tool for the job. With three models covering the range of –25 °C to 660 °C, this family of Metrology Wells calibrates a wide range of sensor types. The optional process version (models 914X-X-P) provides a built-in two-channel thermometer readout that measures PRTs, RTDs, thermocouples, and 4-20 mA transmitters which includes the 24 V loop supply to power the transmitter.

Each process version accepts an ITS-90 reference PRT. The built-in readout accuracy ranges from ± 0.01 °C to ± 0.07 °C depending on the measured temperature. Reference PRTs for Field Metrology Wells contain individual calibration constants that reside in a memory chip located inside the sensor housing, so sensors may be used interchangeably. The second channel is user-selectable for 2-, 3-, or 4-wire RTDs, thermocouples, or 4-20 mA transmitters. For comparison calibration, don’t hassle with carrying multiple instruments to the field. Field Metrology Wells do it all as a single instrument.

Traditionally, calibrations of temperature transmitters have been performed on the measurement electronics, while the sensor remained uncalibrated. Studies have shown, however, that typically 75 % of the error in the transmitter system (transmitter electronics and temperature sensor) is in the sensing element. Thus, it becomes important to calibrate the whole loop—both electronics and sensor.

The process option of Field Metrology Wells makes transmitter loop calibrations easy. The transmitter sensor is placed in the well with the reference PRT and the transmitter electronics are connected to the front panel of the instrument. With 24 V loop power, you are able to power and measure the transmitter current while sourcing and measuring temperature in the Field Metrology Well. This allows for the measurement of as-found and as-left data in one self-contained calibration tool.

All Field Metrology Wells allow for two types of automated thermostatic switch test procedures—auto or manual setup. Auto setup requires the entry of only the nominal switch temperature. With this entry, it will run a 3-cycle calibration procedure and provide final results for the dead band temperature via the display. If you need to customize the ramp rate or run additional cycles, the manual setup allows you to program and run the procedure exactly how you would like. Both methods are fast and easy and make testing temperature switches a virtual joy!

Metrology performance for high-accuracy measurements
Unlike traditional dry-wells, Field Metrology Wells maximize speed and portability without compromising the six key metrology performance criteria laid out by the EA: accuracy, stability, axial (vertical) uniformity, radial (well-to-well) uniformity, loading, and hysteresis. All criteria are important in ensuring accurate measurements in all calibration applications. Field Metrology Well displays are calibrated with high-quality traceable and accredited PRTs. Each device (process and non-process versions) comes with an IEC-17025 NVLAP-accredited calibration certificate, which is backed by a robust uncertainty analysis that considers temperature gradients, loading effects, and hysteresis. The 9142 and 9143 have a display accuracy of ± 0.2 °C over their full range, and the 9144 display accuracy ranges from ± 0.35 °C at 420 °C to ± 0.5 °C at ± 660 °C. Each calibration is backed with a 4:1 test uncertainty ratio.

New control technology guarantees excellent performance in extreme environmental conditions. The 9142 is stable to ± 0.01 °C over its full range and the mid-range 9143 is stable from ± 0.02 °C at 33 °C and ± 0.03 °C at 350 °C. Even at 660 °C, the 9144 is stable to ± 0.05 °C. But this is not all! Thermal block characteristics provide radial (well-towell) uniformity performance to ± 0.01 °C. Dual-zone control helps these tools achieve axial uniformity to ± 0.05 °C at 40 mm (1.6 in).

Automation and documentation make each unit a turnkey solution
So you now have a precision calibration instrument that has field-ready characteristics, accredited metrology performance, built-in two-channel thermometry, and automation— what else could you ask for? How about all this and a turnkey solution that will automate and document the results?

The process versions of Field Metrology Wells have onboard non-volatile memory for documentation of up to 20 tests. Each test can be given a unique alphanumeric ID and will record block temperature, reference temperature, UUT values, error, date, and time. Each test can be easily viewed via the front panel or exported using Model 9930 Interface-it software, which is included with each shipment. Interface-it allows you to pull the raw data into a calibration report or an ASCII file.

Operation is as easy as 1-2-3
You’ll find Field Metrology Wells intuitive and easy to use. Each unit is equipped with a large, easy-to-read LCD display, function keys, and menu navigation buttons. Its “SET PT.” button makes it straightforward and simple to set the block temperature. Each product has a stability indicator that visually and audibly tells you the Field Metrology Wells is stable to the selectable criteria. Each unit offers preprogrammed calibration routines stored in memory for easy recall, and all inputs are easily accessible via the front panel of the instrument. Never buy a temperature calibration tool from a company that only dabbles in metrology (or doesn’t even know the word). Metrology Wells from Fluke are designed and manufactured by the same people who equip the calibration laboratories of the world’s leading temperature scientists. These are the people around the world who decide what a Kelvin is! We know a thing or two more about temperature calibration than the vast majority of the world’s dry-well suppliers. Yes, they can connect a piece of metal to a heater and a control sensor. But we invite you to compare all our specs against the few that they publish. (And by the way, we meet our specs!).

Typical applications

  • Loop calibration of temperature transmitters
  • Thermocouple calibration or verification
  • Calibrations of RTDs or PRTs
  • Testing of thermostatic switches

Q & A

Q: There are several versions of this product?  How are they different?
A: There are several differences between the Fluke metrology wells.  First, the Fluke 9142, 9143 and 9144 each cover a different temperature range. 
  • 9142        –25 °C to 150 °C (–13 °F to 302 °F)
  • 9143        33 °C to 350 °C (91 °F to 662 °F)
  • 9144        50 °C to 660 °C (122 °F to 1220 °F)
Q: How do I pick which insert I need?
A: Within each of the three series, 9142, 9143, and 9144, there is a separate model listed for each insert type, labeled A through F.  The inserts have different size holes.  There is a diagram of each unit on page 5 of the document: Datasheet

Q: Is the Fluke 9144 accurate?  The device I need to calibrate is several inches long.  Won't the temperature because unequal at different spots.
A: The Fluke 9144 divides inserts into different zones, and treats each one separately.  This provides an even temperature distribution vertically, or axial uniformity.
 
Q: Does the Fluke 9144 take a long time to reach a desired temperature?
A: No.  The 9144 was built with for both speed and accuracy.  In 15 minutes, it can heat from 50 to 660 degrees Celsius.  In 35 minutes, it can cool from 660 to 50 degrees Celsius.
 
Q: I need my unit to have a NIST traceable calibration.  Is there an extra charge for that?
A: No.  Your Fluke 9144 includes a NIST calibration, and is ready to use.
 
Q: I will be taking my Fluke 9144 out to jobsites and want to keep it safely stored.  Does Fluke make a case for this?
A: Yes.  The case for the Fluke metrology well can be seen through the link: CASE

Q: Is it possible to purchase additional inserts, so I can have all of the sizes for my unit?
A: Yes.  It is possible to purchase additional inserts to expand the possibilities of what you can test with your Fluke 9144.
