Product Description
Ordering KeyCGESC02D2 V L N
Duct mounted CO2transmitters of the CGES series are designed forHVAC applications. The CO2sensing element uses theNon-Dispersive Infrared Technology(NDIR). A patented auto-calibration procedure compensates for drift caused by the aging ofthe sensing element and guarantees outstanding long term stability. Installed into a duct a small flow of air will be established byconvectionthroughthe
probe into the transmitter housing andbackintothe duct. Inside the transmitter housing theairwilldiffuse through a membrane into the CO2sensing element.
Measuring ranges of 0...2000ppm and 0...5000ppm correspond toananalogue interface of
0-10V or 4-20mA. The instruments can be easily positioned in the duct with the standard mounting flange.
