Measures temperature and humidity / output as 0 .. 10 V signal / compact
Modbus RTU interface / wall mounting
The humidity sensor PCE-P18 is used in HVAC technology to monitor humidity and temperature. The measured values are output by the PCE-P18 humidity sensor as a 0 … 10 V standard signal. In this compact humidity sensor, air humidity and temperature are precisely determined using a semiconductor component. For commissioning, the humidity sensor PCE-P18 is supplied via a DC voltage. The measured variables are output via a two-wire line. All connections are made via screw contacts in the waterproof IP 65 housing. In addition to the output of the measurement signal as a 0 … 10 V signal, the measurement values can be output via the RS485 interface. This function is particularly useful if several measuring points are to be linked to one another during your home surveillance.
