9144-C-P-156 Metrology Well Overview

Fluke's 9144 Field Metrology Wells extend high performance to the industrial process environment by maximizing portability, speed, and functionality with little compromise to metrology performance. It's 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.

The 9144 Metrology Wells come with a large, easy-to-read LCD display, function keys, and menu navigation buttons. The "SET PT." button simplifies the process of setting the block temperature. Each product includes a stability indicator that visually and audibly signals when the Field Metrology Wells are stable to the selectable criteria. Each unit also offers preprogrammed calibration routines stored in memory for easy recall, with all inputs conveniently accessible via the instrument's front panel.

The optional process version (models 9143-X-P) includes a built-in two-channel thermometer readout that measures PRTs, RTDs, thermocouples, and 4-20 mA transmitters, including a 24 V loop supply to power the transmitter. The second channel is user-selectable for 2-, 3-, or 4-wire RTDs, thermocouples, or 4-20 mA transmitters. For comparison calibration, there's no need to carry multiple instruments to the field; Field Metrology Wells serve as a comprehensive single instrument.

Lastly, the process version features onboard non-volatile memory capable of documenting up to 20 tests. Each test can be assigned 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 the included Model 9930 Interface-it software, which allows you to pull the raw data into a calibration report or an ASCII file.

9140 Series Field Metrology Wells

Unlike traditional dry-wells, the 9140 Series 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 units also accommodate various probe sizes with multiple-hole inserts.
