Siemens QPM Duct CO2 Sensors
The QPM Series Duct CO2 Sensors monitor and transmit changes in CO2 to the building control systems. Several models are available for CO2 only, CO2/Temp, CO2/Temp/RH and CO2/VOC. All variants for CO2 and combination versions with Temperature or VOC deliver 0 to 10 Volt to 5 Volt (field selectable) proportional signals to the controller. No calibration of the CO2 sensor is necessary — these microprocessor-based units consist of an NDIR sensor that experiences less than 1% drift per year for the first two years of operation and negligible drift thereafter. These units are especially suited for applications where precise, stable CO2 sensing is required.
