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.
