EE820 CO2 transmitter for climate technology and building

EE820 CO2 transmitter for climate technology and building The EE820 is designed for use in harsh, demanding applications. A multip-point CO2 and temperature factory adjustment procedure leads to an excellent CO2 measurement accuracy over the entire temperature working range. The EE820 incorporates the E+ E dual wavelength NDIR CO2 sensor, which compensates for ageing effects, is highly insensitive to pollution and offers outstanding long term stability. With its robust, functional housing and a special integrated filter the EE820 can be installed in polluted applications such as agriculture and livestock barns. The M12 connector option facilitates easy removal of the EE820 before site cleaning operations. An optional kit facilitates easy configuration and adjustment of the EE820. Key Features E+ E dual wavelength NDIR CO2 working principle Measuring range up to 10, 000ppm Auto-calibration for excellent long term stability Temperature dependency of only 1ppm CO2/ ° C Robust and functional enclosure Highly insensitive to pollution Voltage or current analogue outputs Fast and easy installation Easy user configuration and adjustment Typical Applicatons Greenhouses Fruit and vegetable storage Stables Hatcheries and Incubators Vehicles, Trains, Trams Measuring range 0...2000 / 5000 / 10000ppm Outputs 0...5V / 10V or 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
