| Recently, we introduced Metrology Wells, which
provide the very best performance in portable temperature
calibration. The new 914X 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.

High Performance for the Industrial
Environment
Field Metrology Wells are designed for the industrial process
environment. They weigh less than 8.2 kg (18 lb) and have a small
footprint, which makes them easy to transport. Optimized for
speed, Field Metrology Wells cool to –25°C in 15 minutes and heat
to 660°C in 15 minutes.Field environment conditions are
typically unstable, having wide temperature variations. Each Field
Metrology Well has a built-in gradient-temperature compensation
(patent pending) that adjusts control characteristics to ensure
stable performance in unstable environments. In fact, all
specifications are guaranteed over the
environmental range of 13°C to 33°C. |
