AERASGARD KCO
Patented quality product (patent no. DE 10 2014 010 719.1)
The maintenance-free microprocessor-controlled duct sensor AERASGARD
without display, is used for detecting the CO
into standard signal of 0 -10 V.
The maintenance-free microprocessor-controlled duct sensor AERASGARD
switches), enclosure with quick-locking screws, optionally with / without display, is used for detecting the CO
0...2000 ppm or 0...5000 ppm. The measurement value is converted into standard signal of 0 -10 V or 4...20 mA.
The CO content of the air is measured using an optical NDIR sensor (non-dispersive infra-red technology). The detection range of the CO
2
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 CO
2
light source and a receptor. A certain range of wavelengths of light radiated by the source is damped and absorbed by CO
section. This damping is detected by the receptor.
