DEW POINT SENSOR

MEASURE TO MANAGE

Section 4 : How to Choose the correct Sensor for your
Application :

4.1 Dew Point Sensor - WADS 201 Series

Compact sensor for Refrigerant or Desiccant Dryers

WADS 201 Dew Point Sensor is suitable for refrigerant, desiccant and

membrane  dryers.  Its  proven  polymer  ﬁlm  technology  provides  strong
contamination  resistance. The precision sensor design compensates for drift
caused  by  temperature,  contamination  and  ageing,  providing  long-term,
reliable, high-accuracy measurements.

Note: WADS 201 Series dew point sensor is not recommended for

desiccant dryers with a dew points below -60°C. This dew point
sensor does not have an optional pressure sensor.

4.2 Dew Point Sensor - WADS 202 Series

For Refrigerant or Desiccant Dryers with dew point of -60°C to +60°C

This precision dew point sensor is suitable for refrigerant, desiccant and

membrane  dryers.  Its  proven  polymer  technology  provides  strong
contamination  resistance. The precision sensor design compensates for dri2
caused  by  temperature,  contamination  and  ageing,  providing  long-term,
reliable, high-accuracy measurements.

Note: The 202 Series dew point sensor is not recommended for dew
points below -50°C (-58°F).
