Dewpoint Transmitter for General Applications Features and Benefits Long-lasting bulk Polymer sensing element offers excellent accuracy, stability and response speed IP66 / NEMA 4 Weatherproof Protection Compact 2-wire 4-20 mA Loop Powered Dewpoint Transmitter Supplied with a calibration certificate traceable to National and International Humidity standards Various dewpoint ranges available, -60 °C to +50 °C Economical solution for higher ‘wetter’ dewpoints, e.g. monitoring refrigerant driers DS4000 Hygrometer (Advanced) Optional Sensor Holder/Sample Cell for optimum sampling conditions The PDT Dewpoint Transmitter utilises a bulk Polymer sensing element. It is an economical choice for higher or ‘wetter’ dewpoints where your application only requires readings down to -60 °C dewpoint. Dewpoint ranges are offered as: -60 °C to +20 °C, -40 °C to +30 °C and -20 °C to +50 °C dewpoint. This compact, 2-wire, 4-20 mA Loop Powered Dewpoint Transmitter is used for trace moisture measurement in gases and dry compressed air. Applications include refrigerant dryers, cool stores, switchgear monitoring and more. Very easy to install, requiring little or no maintenance. Long-lasting bulk Polymer sensing element offers excellent sensitivity, repeatability, and response speed. Available separately, or combined with the DS4000 or DS1200 Display Indicators to make up a Hygrometer System. An alternative option is a combined system integrating the DIS030, a compact 4-20 mA Loop Powered Local Display that mounts directly on to the PDT Transmitter, as pictured above. The PDT can be fitted directly into the pipeline, or our dedicated Dewpoint Sensor Holder/Sample Cell. The Dewpoint Sensor Holder/Sample Cell is highly recommended for optimum sampling conditions and allows the Transmitter to be removed for annual laboratory dewpoint calibration without interrupting the process.
