Model DS1200-PDT 4-20mA In-Line Dewpoint Hygrometer has a two wire 4-20mA transmitter designed for continuous measurement of moisture content in gases or compressed air.
The long lasting Polymer sensing element can be utilised to measure the moisture content in many applications, see examples below. The PDT transmitter can also be factory configured to give a 4-20mA linear signal for %RH. It is supplied with a Certificate of Calibration traceable to international humidity standards.
The Model PDT transmitter has been designed to cope with extreme environmental conditions. The rugged stainless steel construction offers protection to NEMA4 (IP65), with transmitter electrical connections made via secure industrial connector.
