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.
