Duct Humidity Sensors

Highly Precise & Rugged

On-Wall Humidity Sensors


Duct Humidity Sensors also in
Facility & Industrial Bus Versions

Digital humidity sensor devices with integrated temperature sensor ensure highly accurate measuring results thanks to small hysteresis and long-term stability. The modular design of our Tyr 2 housing family adds versatility. Both the high-impact plastic housing and the extremely rugged stainless steel housing are available for electrical connection using cable glands or M12 connectors.

Also available in EtherCAT P capable and
multifunctional Modbus versions.
