Humidity & Temperature Sensors with Digital O/P (A & B Series Digital RS485/RS232)

Humidity and Temperature Sensor for advanced requirements

The robust devices are available to be mounted in ducts, on walls, or are available with a stainless steel probe which can be up to 5 m away from the output electronics. Depending on the application, we either recommend using transmitters with exchangeable or permanently assigned probes. The type of filters and filter materials can be adapted to suit the respective protection category required (up to IP65).

Depending on the individual design, the sensors can be used at temperatures of between -80 °C and +200 °C and at pressures of up to 25 bar in non-corrosive air. These sensors are used in industrial process automation, pharmaceutical industry, automation of production, humidity and temperature measurement in the quality control and many other applications.
