Model PDT Dewpoint Transmitter is a two wire 4-20mA transmitter for continuous measurement of moisture in a process gas or compressed air that will give a linear 4-20mA signal corresponding to the dewpoint. It is ideally suited for monitoring the moisture content of compressed air from refrigerant driers. See other applications on our datasheet below.
The Model PDT dew-point transmitter can also be factory configured to give a 4-20mA linear signal for %RH. The long lasting Polymer 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 better than ±2°C dewpoint. The Model PDT transmitter has been designed to cope with extreme environmental conditions. The rugged stainless steel construction offers protection to IP65 (NEMA4), with transmitter electrical connections made via secure industrial connector.
Model PDT transmitter can withstand 5,000kPa (50bar) maximum pressure. Designed with the operator in mind, for reliable and accurate measurements, the Model PDT is extremely easy to install and operate, requiring little or no maintenance. The Model PDT transmitter is supplied with a Certificate of Calibration, an instruction manual and 2m of quality connecting cable. Additional accessories for this transmitter are available from stock.
By using a high quality very low resistance cable, the transmitter can be located at long range distances, in excess of 1500+ metres from the control room.
