Field-Metrology Wells

Aug. 9, 2007
The 9140 Series of field-metrology wells provide stability to ±0.

The 9140 Series of field-metrology wells provide stability to ±0.01°C, radial uniformity to ±0.01°C, axial uniformity at 40 mm to ±0.04°C, loading to ±0.006°C, and hysteresis to ±0.015°C. Each unit weighs about 16 lb and will reach 660˚C in less than 15 min. Each process version has a built-in reference thermometer readout that accepts reference probes with smart six-pin DIN connectors that store probe characterization in the connector. A second channel measures resistance, voltage, or 4-to20-mA current. The process version has 24-V loop power for calibration of temperature transmitters.

All field-metrology wells have an LCD display and menu-driven interface, a dedicated temperature setpoint and °C/°F buttons. Preprogrammed tasks and temperature points can be saved and recalled for route calibrations. All inputs and terminals are located on the front of the unit for easy access.
