The maintenance-free, microprocessor-controlled AERASGARD® ACO2 – SD is designed for on-wall installation and is used to detect the CO2 content of the air. The measurement signals are converted to standard signals of 0 -10 V.
The CO2 content of the air is measured using an optical NDIR sensor (non-dispersive infra-red technology). The detection range of the CO2 sensor 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 AERASGARD® CO2 sensors.
A measuring system based on NDIR (non-dispersive infra-red technology) for CO2 measurement consists of a light source and a receptor. A certain range of wavelengths of light radiated by the source is damped and absorbed by CO2 molecules in the measured section. This damping is detected by the receptor
