The AMT-Ex edition Dew-point Transmitter is utilized for uninterrupted measurement of moisture content in a process gas and can also be employed in compressed air applications. The transmitter has a continuous 4-20 mA output signal in correlation to the dew-point temperature in either °C & °F Dew-point, ppm(v), g/m3 or lb/MMSCF. This endurable Aluminium Oxide detecting element provides high quality sensitivity, redundancy and response speed. Every unit is furnished with a Certificate of Calibration in accordance with the International Humidity standards and regulations, verifying ±2°C dew-point precision. The AMT-Ex is ATEX verified and is safe for employment in unstable areas when established with a corresponding separator.
The transmitter has an integrated Automated Calibration (AUTOCAL) characteristic, which allows the user to execute a field calibration / span check. This feature is operated by means of two small button switches constructed within the transmitter enclosing.
