This high-performance dew point sensor is designed for all types of compressed air dryers, supporting multiple measuring ranges including –80…+20 °Ctd, –60…+30 °Ctd, and –20…+50 °Ctd. It provides gas-independent measurement, making it suitable for compressed air as well as other non-corrosive gases.
The sensor element is insensitive to condensation and water, ensuring reliable operation even in challenging conditions. With excellent long-term stability and drift resistance, calibration intervals are optimized, reducing maintenance effort and operational costs.
Fast response times—especially during moisture ingress—ensure accurate and timely monitoring. The robust design supports high-pressure applications, with a special version rated up to 500 bar, and flexible interface options allow seamless integration into modern control systems.
