风道空气质量传感器     QPM11… 
                                QPM21… 

o maintenance-free CO2 sensing element (depending on the type) based on optical infrared absorption measurement (NDIR1)
o or with VOC2) sensing element, based on a heated tin dioxide semiconductor
o CO2 temperature (active or passive) and CO2 humidity-temperature multisensor
o No recalibrations required
o Operating voltage AC 24 V or DC 15…35 V
o Signal outputs DC 0...10 V or DC 0...5 V adjustable
o Selectable passive temperature sensing element 


1)  NDIR = Non dispersive infrared
2) VOC = volatile organic compounds (also called mixed gas)
