Description

Measures temperature and humidity / output as a 4 ... 20 mA signal / compact

Modbus RTU interface / wall mounting

The humidity sensor is used in HVAC technology to monitor humidity and temperature. The measured values ​​are output by the humidity sensor as a standard signal 4 ... 20 mA. In this compact humidity sensor, air humidity and temperature are precisely determined using a semiconductor component. For commissioning, the humidity sensor 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 4 ... 20 mA 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.
