The new 9140 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 documentation. Combined, the three models (9142, 9143, and 9144—each with a “process” option) cover the wide range of –25°C to 660°C.

† The temperature range
may be limited by the reference probe connected
to the readout. The Built-In Reference
Thermometer Readout Accuracy does not include
the sensor probe accuracy. It does not include
the probe uncertainty or probe characterization
errors.
‡ Measurement accuracy
specifications apply within the operating range
and assume 4-wires for PRTs. With 3-wire RTDs
add 0.05 ohms to the measurement accuracy plus
the maximum possible difference between the
resistances of the lead wires. |
