Small dry wells for big field applications
Description
The 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 automation and
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. |
