Siemens QSM2100 Air Quality Sensor

The Siemens fine dust duct sensor designed to enhance room comfort and optimize energy consumption in ventilation and air conditioning plants. This sensor acquires PM2.5 and PM10 concentrations, relative humidity, and duct air temperature. It operates on AC 24 V or DC 15 to 35 V and offers signal outputs of DC 0 to 10 V or DC 0 to 5 V or 4 to 20 mA, which are adjustable. With a range of use from -5 to 45 °C and 5 to 95 % r.h., it provides accurate and reliable measurements for demand-controlled ventilation.
