Dew point sensor ensures compressed air quality and reduces energy costs

Clean and dry compressed air

Monitoring the pressure dew point is a key process in compressed air lines and tanks to ensure air quality and operational safety. The pressure dew point indicates the temperature at which the water vapour contained in the compressed air condenses – at constant pressure.

Excessive moisture leads to corrosion and potential leaks, shortens system service life and impairs the function of compressed air-powered devices. Dry compressed air is essential for troublefree processes and compliance with standards, particularly in sensitive areas such as the food and pharmaceutical industries or in precision pneumatic control systems.

Optimised compressed air treatment

The new dew point sensor from ifm makes a decisive contribution to efficient compressed air treatment. It measures the pressure dew point with high precision – the lower this value, the drier the compressed air.

Continuous air quality monitoring enables demand-based control of dryers. This prevents unnecessary "over-drying", saves energy and reduces costs.

The sensor does not directly supply the required air but performs a monitoring function. It ensures that components such as dryers and other system parts operate correctly, and it immediately detects any deviations, enabling the user to take prompt corrective action. Therefore, its primary purpose is quality monitoring, while also indirectly helping to prevent downtime.
