AERASGARD® KCO2-W DISPLAY

Item No. 1501-3140-7321-200
EAN 4 251325 613031

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

The maintenance-free microprocessor-controlled duct sensor AERASGARD® KCO2 - SD with automatic
calibration (fixed), enclosure with snap-on lid, without display, is used for detecting the CO2 content
of the air within a range of 0...2000 ppm or 0...5000 ppm. The measurement value is converted into
standard signal of 0 -10 V.

The maintenance-free microprocessor-controlled duct sensor AERASGARD® KCO2 - W with automatic
calibration (can be deactivated via DIP switches), enclosure with quick-locking screws, optionally
with / without display, is used for detecting the CO2 content of the air within a range of 0...2000 ppm
or 0...5000 ppm. The measurement value is converted into standard signal of 0 -10 V or 4...20 mA.

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.
