4-20 mA dewpoint transmitter PDT

2-wirestainless steelfor trace moisture measurements

• Long-lasting bulk Polymer sensing element offers excellent accuracy, stability and response speed • Various dewpoint ranges available, -60 °C to 50 °C • Compact 2 Wire 4-20 mA Loop Powered Dewpoint Transmitter • Economical solution for higher ‘wetter’ dewpoints, e.g., monitoring refrigerant driers • IP66 / NEMA 4 Weatherproof Protection The PDT Dewpoint Transmitter utilises a bulk Polymer sensing element. It is an economical choice for higher ‘wetter’ dewpoints where your application only requires readings down to -60 °C dewpoint, e.g., monitoring refrigerant driers. Three dewpoint ranges are offered: -60 °C to 20 °C dewpoint, -40 °C to 30 °C dewpoint and -20 °C to 50 °C dewpoint. The PDT is available separately for integration into your control system or combined with the DS1200 or DS4000 Indicators. The PDT Transmitter can also be combined with the DIS030 Round Display, a compact 4-20 mA Loop Powered Local Indicator that mounts directly on the Transmitter. The long-lasting bulk Polymer sensing element offers excellent sensitivity, repeatability, and response speed. 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. 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.
