Digital exchangeable humidity temperature sensor PMU-P

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

General information

  • with asynchronous ASCII transmission protocol
  • calibrated for relative humidity and temperature
  • exchangeable, plug-in design
  • housing made of plastic


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

The exchangeable digital sensor PMU-P is equipped with the Mela humidity measuring element humidity measuring element FE09/4. Protected by a PTFE pocket filter, the measuring element measures the air humidity. The pocket filter consists of porous vapour-permeable material and protects the sensor element from most dirt, dust and pollutants. The electronics and the plug contacts on the back are ex- trusion-coated with plastic to make them watertight.
