The QSM2162 duct sensor measures the concentration of fine dust particles PM2.5 and PM10, relative humidity and temperature in heating and air conditioning systems. In the case of delicate parts, the output is a moving average of the latest data from the sensor for the last 10 s. The sensor is able to communicate with all controllers processing the 0...10 V / 0...5 V / 4...20 mA signal.

The sensor is equipped with 3 outputs , so it is possible to choose what the sensor will detect : fine dust particles PM2.5, fine dust particles PM10, relative humidity or temperature.

The relative humidity is measured in the application range of 5...95% RH without condensation and in the total measurement range of 0...10% RH The measurement accuracy is 3-5% RH The temperature is measured by the sensor in the selectable range of 0...50 °C or -35...35 °C.

This sensor is not intended as a smoke or gas leak warning. At the same time, the sensors are not intended for outdoor use.
