VP Dew Point Sensor

Prevent high maintenance costs by monitoring and maintaining the right dew point in your system. Too much water in your system can lead to e.g. forming of rust, freezing of valves, and even product loss when the moist content is too high for your coating or paint process. Stay in control of your dew point with the VP Dew Point Sensor.

The VP Dew Point Sensor is the smart dew point transmitter with a large measurement range of -70..+60 ⁰C, so you can measure downstream a refrigerant type dryer as well as a desiccant-type dryer. The sensor has multiple outputs for easy connection to any management system. The alarm LED shows a critical dew point level right on the factory floor and the VP Dew Point Sensor has a built-in autocalibration for high accurate readings.
