AERASGARD® KFTM-CO2-W LCD

Patented quality product (patent no. DE 10 2014 010 719.1)

The maintenance-free, microprocessor-controlled AERASGARD® KFTM - CO2 - W and KLQ - CO2 - W duct air quality transmitters with automatic and manual calibration are used for detecting the overall room climate. They measure CO2 within a range of 0...2000 ppm or 0...5000 ppm, air quality (VOC) in one of three selectable sensitivity levels (LOW/MEDIUM (default)/HIGH, temperature within a range of –35...+80 °C as well as relative humidity from 0...100% r.H. The measured values are converted into standard signals of 0-10 V or 4...20 mA (selectable by means of DIP switches). As an option, the measured values can be shown continuously in the illuminated display.

Relative humidity (% r.H.) is the 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 precise measuring results. The CO2 content of the air is measured using an optical NDIR sensor (non-dispersive infra-red technology). The detection range of the sensor is calibrated for standard applications such as the monitoring of residential and conference rooms. Room ventilation on an as-needed basis, improved well-being and increased comfort as well as reduced operating costs through energy conservation are just some of the benefits of employing our AERASGARD® CO2 sensor devices.
