The AMT Dewpoint Transmitter is a two wire 4-20 mA circle controlled unit, utilized for constant measurement of moisture (dewpoint) levels in gases and dry compressed air, which will output a direct 4-20 mA indicator relating to the dewpoint temperature. The Automatic Calibration (AUTOCAL) functional is worked by method of two little switches on the side of the transmitter enclosure. The AMT Dew-point transmitter can additionally be industrial factory designed to output a 4-20 mA straight sign for any possible moisture unit for instance, ppm(v), ppm(w), g/m3 or lb/MMSCF. Every unit is supplied with a Certificate of Calibration, traceable to International Humidity Standards, accepting precision to ±2 ºC dewpoint. See datasheet in the catalogue section for full details.
