AERASGARD® ATM-CO2-SD-U

Art.nr. 1501-7112-1001-200
EAN 4 251325 616346

The maintenance-free, microprocessor-controlled on-wall sensor AERASGARD® ATM - CO2 - SD   with automatic calibration is used for detecting the CO2 content of the air within a range of 0...2000 ppm or 0...5000 ppm as well as the temperature within a range of –35...+80 °C. The measured values are converted into standard signals of 0 -10 V. 

The relative humidity (% r.H.) quotient of water vapour partial pressure divided by the saturation vapour pressure at the respective gas temperature. A digital, long-term stable sensor used as measuring element for relative air humidity and temperature guarantees exact measurement results. The CO2 content of the air is measured using an optical NDIR sensor (non-dispersive infra-red technology). The detection range of the sensors is calibrated for standard applications such as monitoring residential rooms and conference rooms. Room ventilation on an as-needed basis, improved well-being and customer benefit, increased comfort as well as reduced operating costs through energy conservation are just some of the benefits of employing the AERASGARD® CO2 sensor. The explanations above demonstrate that there are applications for CO2 measurements, for VOC measurem ents, but from our perspective, above all, for a combination of both measurands. The crucial factor in this respect is that both of these measurands are not convertible into each other and derivations to or from one another cannot be made. An NDIR CO2 measuring instrument measures selectively and cannot detect any VOC; a VOC mixed gas sensor cannot recognize CO2 molecules.
