CGESCO2TW2AT04

Environmental SensorsCO2, Relative Humidity / TemperatureTransmitters• CO2/ RH / T measurement in one device• RH output with plug-in module• Analogue or switching output• Modern design• Optional display• Easiest installation• Long term stability• Room transmitter• Wall mounting• CE, RoHSProduct DescriptionCGESC02xxW type set new standards in CO2 measurements for HVAC.The transmitters resp. switches combine CO2, relative humidity (RH) and temperature (T) measurement inone modern and userfriendly housing.The basic CGESC02TW version for CO2and T can be easily extendedwithaRH plug-in module.The CO2 measerument is based on the infrared principle. A patented auto-calibration procedurecompensatesforthe aging of the infrared source and ensures outstanding long term stability.This sensor provides analogue outputs (in V or mA). The optional display indicates sequentially the actual measuring data.As one more option a switching output with adjustable switching point and hysteresis is available.A wide variety of models ensures an optimal adjustment for customised requirements.ApprovalsOrdering KeyCGESC02TW 2 VT04ModelWorking RangeOutputDisplay Temperature Unit Temperature ScaleType SelectionModel (only with switching output)CGESC02W C02ModelCGESC02TWC02+TCGESC02THWC02+T+RHWorking Range20...2000ppm50...5000ppmOutputnot for model CGESC02WV 0-10V4-20mA(only for CGESC02TW)only for model CGESC02WS Switching outputDisplay (not for model CGESC02W)Nil Without DisplayD With DisplayTemp.
