Measures temperature and humidity / output as standard signal / compact Modbus RTU interface / wall mounting / display
The humidity probe PCE-P18 is used in HVAC technology to monitor humidity and temperature. The measured values ​​are output as a standard signal by the humidity sensor PCE-P18. Air humidity and temperature are accurately determined in this compact humidity sensor via a semiconductor component. For commissioning, the PCE-P18 humidity probe is supplied with a DC voltage. The measured values ​​are output via a two-wire cable. All connections are made via screwed contacts in the waterproof IP 65 housing. In addition to the output of the measuring signal as a 0 ... 10 V signal, the measured values ​​can be output via the RS485 interface. This function is useful if several monitoring points are to be linked to each other during your house surveillance.

  • With display
  • Standard signal output
  • Simple wall mounting
  • RS-485 interface
  • For permanent monitoring
  • Various filters available
