Siemens Building Technology QPA2060D Sensor mario 35" WC to meet theThe Siemens QPA2060D is a dual function room air quality sensor engineered for precise demand controlled ventilation (DCV) in commercial HAVC systems. Utilizing infrared absorption technology (NDIR) for CO2 monitoring, this unit delivers a stable 0 10Vdc output signal across a detection range of 0 2000 PPM. The integrated temperature sensing capabilities allow for simultaneous climate monitoring, reducing the need for multiple wall mounted devices.
