Dew Point Monitoring

Humidity has unfavorable effects on compressed air distribution systems and on the processes in which it is used. When used to actuate pneumatic valves, cylinders and controllers, excess moisture in the air can cause corrosion problems, loss of instrument sensitivity, and even rapid changes in calibration. Conversely, dry air will lead to increased lifespan and reliable operation of sensitive instrumentation.

The moisture content becomes even more critical when used in food, beverage, and pharmaceutical applications and most importantly breathing air applications. The presence of excess moisture in breathing air can lead to freezing in the pressure regulator and ice blocking the orifice, causing an interruption to the supply of air to the user.

Our dew point sensors can measure and record within the range of -80ºC to 40ºC with an accuracy of +/- 2ºC. Each sensor is individually computer calibrated against known moisture concentrations. Again, this data can be plotted and referenced against other variables that are simultaneously being measured.
