Unlike its sister product, the Fluke 9173-X-256 Field Metrology Well, this instrument includes integrated reference thermometry which allows it to accept and read 100Ω, 25Ω and 10Ω PRTs. It is compatible with all of Fluke’s PRTs and is able to accept unique ITS-90 characterisation coefficients from these instruments, thereby allowing the Fluke 9173-X-R-256 Field Metrology Well to utilise the accuracy of PRTs. It is able to read PRTs to an accuracy of up to ±0.011°C (dependent on temperature and probe type) and is supplied with an accredited, traceable calibration.
As standard the Fluke 9173-X-R-256 Field Metrology Well is calibrated using traceable, accredited PRTs, this helps to both limit hysteresis to 0.07°C and maintain the instrument’s display accuracy of ±0.25°C (at 700°C). The inclusion of Fluke’s patent-pending proprietary electronics and dual-zone control (digital and analogue) also helps to maintain its display accuracy and repeatability, as well as limit temperature gradients and loading effects.
These two features, combined with the instrument’s 203mm-deep well, reduce loading effects to between ±0.02°C and ±0.04°C (depending upon the generated temperature). The depth of this well also ensures that the calibrator is able to produce a homogeneous temperature zone of 60mm (from the bottom of the well) and is able to maintain an axial uniformity of ±0.1°C to ±0.25°C, and radial uniformity of ±0.01°C to ±0.04°C. In addition to this, it is able to offer a heat stability of between ±0.005°C and ±0.03°C (dependent on temperature).
The depth of the instrument’s well also contributes to the accuracy of calibration procedures, as it facilitates the complete immersion of the instrument-under-investigation, thereby ensuring that all the instrument's characteristics, including the location and size of the sensor, the width and thermal mass of the probe, as well as any external leads, are accounted for during the calibration.
With the inclusion of all these features, the Fluke 9173-X-R-256 Field Metrology Well is complaint with the six critical components of performance detailed in the European Metrology Community’s EA 10-13 document:
- Calibrated display accuracy
- Stability
- Axial uniformity
- Radial uniformity
- Loading effects
- Hysteresis
Therefore, the Fluke 9173-X-R-256 Field Metrology Well is able to provide the operator with the stability, accuracy and uniformity of a bath temperature calibrator but with all the convenience and practicality of a dry well tester.
The Fluke 9173-X-R-256 Field Metrology Well's design is modelled after that of dry well calibrators; it is lightweight, compact and rugged and can be used in a variety of industrial and hard-to-access environments.
Adding to this instrument’s practicality and expanding its scope-for-use is the inclusion of an RS-232 interface and Fluke’s Interface-It Software. These components facilitate the user’s ability to operate the Fluke 9173-X-R-256 Field Metrology Well remotely from his/her PC. The user is able to view calibration results via his/her PC and can access and adjust the metrology well’s features, functions and settings in order to run calibration procedures remotely.
In addition to this, the Fluke 9173-X-R-256 Field Metrology Well can be used with Fluke’s MET/ TEMP II Software (NOT included) to perform automated calibrations of RTDs, thermocouples and thermistors.
Alternatively, the user can configure the instrument via its front panel utilising the large, LCD display; on-screen menus and a numeric keypad to make adjustments. The Fluke 9173-X-R-256 Field Metrology Well includes four pre-programmed calibration tasks into which the user may enter up to eight temperature set-points with ‘ramp and soak’ times between each point. He/she can also access the Switch Test protocol, optimised for zeroing-in on ‘dead-bands’ for thermal switches.
Via the large, LCD display the user can view the block temperature, cut-out temperature, reference thermometer temperature, stability criteria and ramp rate. He/she may also set the menus to display in English, French or Chinese and can choose to view measurements in °C or °F using the dedicated function button.
This selection of features and functions along with the Fluke 9173-X-R-256 Field Metrology Well with Built-in Reference Thermometry’s sophisticated design makes it ideal for accurately calibrating temperature sensing instruments at high temperatures.
