EE850 CO2 and temperature transmitter for ventilation ducts

EE850 CO2 and temperature transmitter for ventilation ducts EE850 CO2 and Temperature Transmitter for Duct Mounting The EE850 is optimized for use in building management applications. A multi-point CO2 and temperature factory adjustment procedure leads to an excellent CO2 measurement accuracy over the entire temperature working range. The E+ E dual wavelength NDIR CO2 sensor compensates for aging effects, is highly insensitive to pollution and offers outstanding long term stability. The EE850 can be optionally fitted with a passive temperature sensor output. An optional kit facilitates easy configuration and adjustment. Key Features E+ E dual wavelength NDIR CO2 working principle Measuring range up to 10, 000ppm Auto-calibration for excellent long term stability Temperature compensation Highly insensitive to pollution Voltage or current analogue outputs Optional passive temperature sensor Fast and easy installation Easy user configuration and adjustment Typical Applications Building management Demand controlled ventilation Process control Measuring range 0...2000 / 5000 / 10000ppm; -20...60° C Outputs 0-5 / 10V; 4...20mA Accuracy 0...2000ppm: < ± ( 50ppm + 2% of measuring value) 0...5000ppm: < ± ( 50ppm + 3% of measuring value) 0...10000ppm: < ± 100ppm + 5% of measuring value) Supply 24V AC/ DC
