Sensors with digital output signal

I Series


  • very precise and robust
  • operating temperature -40 °C bis +85 °C
  • humidity measuring range 0...100% r.h.
  • digital data transfer
    - RS485 Modbus RTU Protocol
    - RS232 ASCII Protocol
  • with plug-in connection or with robust head
  • for meteorological applications optional with filter

  • Humidity ± 1,5 %rh 10...90 %rh at 25 °C
  • Temperature ± 0,15 K at 25 °C

Humidity/-temperature sensors in the I series are compact probe sensors with cable, connecting head or plug-in connection to measure relative humidity and temperature with high precision. They can be used for a wide range of applications.

The sensors in this series have got either a RS485-interface and are suitable for data transfer via MODBUS-RTU protocol
or they have got a RS232-interface and are suitable for data transfer via ASCII protocol.
