solar radiation sensor
SIEMENS Building Technologies
The QLS60 solar sensor is ideally suited for utilization as a reference sensor ventilation, air conditioning and heating plants which necessitate compensation of solar radiation. Buildings or building sections that are equipped with large window areas are exposed to strong solar radiation which is why they require solar compensation. This applies most especially to plants that do not utilize thermostatic radiator valves cannot be used.
The QLS60 solar sensor has an IP65 protection class, range of 0 up to 1000 W/m2, an output of DC 0…10 V / 4…20 mA and supply of AC 24 V / DC 18…30 V.
