Model AMT-Ex Dewpoint Hygrometer is a three wire 4-20mA transmitter, used for continuous measurement of humidity in a process gas or compressed air, which will output a linear 4-20mA signal corresponding to the dewpoint temperature. The Model AMT-Ex transmitter can also be factory configured to output a 4-20mA linear signal for any other moisture unit e.g. ppm(v), ppm(w), g/m3, lb/MMSCF etc.

The long lasting sensing element offers excellent sensitivity, repeatability and response speed. Each unit is supplied with a Certificate of Calibration, traceable to International Humidity Standards, validating accuracy to ?? dewpoint.
Model AMT-Ex is ATEX certified and provides an Intrinsically Safe Dewpoint Transmitter for hazardous area use when installed with the appropriate isolator.
The transmitter also incorporates an Automatic Calibration (AUTOCAL) feature, which allows the user to carry out a field calibration / span check. AUTOCAL feature is operated by means of two small button switches built within the transmitter enclosure. |
