Dew point measurement

Continuous measurement of dew point Ideal for monitoring refrigeration, adsorption and membrane dryers Prevention of system damage and contamination of end products

How we measure

Why dew point sensors are indispensable

In industry, the quality of compressed air is crucial for the reliability and efficiency of your systems. Pressure dew point sensors play a central role in ensuring this quality. They precisely monitor the moisture content of the compressed air.

Dew point measurement

Why should the dew point be constantly measured in your system?

Equipment and component protection
  • Prevention of corrosion, as condensate can attack metal parts
  • Reduction of wear on valves, cylinders, and piping
  • Avoidance of blockages in filters and dryers due to water accumulation
  • Protection against frost damage in cold operating environments
  • Extension of component lifespan through targeted maintenance
Optimization of compressed air treatment
  • Ensures the effectiveness of air dryers via continuous monitoring
  • Allows adjustment of filtration and drying processes based on current moisture levels
  • Facilitates early detection of malfunctions in the treatment system
  • Optimizes operating parameters for targeted air drying
  • Improves air quality, positively impacting process and end-product quality
  • Enables energy savings through demand-driven treatment cycles
Economic efficiency and process safety
  • Reduces maintenance and repair costs through preventive measures
  • Minimizes production downtime caused by moisture-related issues
  • Enhances overall system safety and reliability
  • Maintains consistent process quality with controlled air conditions
  • Increases energy efficiency within the system
  • Achieves long-term cost savings by reducing disturbances and optimizing operations
