AERASGARD RTM - CO
The maintenance-free, microprocessor-controlled AERASGARD
to detect the CO content in air within a range of 0 ppm to 2000 ppm CO
2
actual temperature is also measured at the same time. The measurement signals
are converted to standard signals of 0 - 10 V. Optionally, this CO
ducer can be supplied with switching output. Elegant enclosure made of plastic, with
snap-on lid, base with 4-hole attachment for installation on vertically or horizontally
installed in-wall flush boxes, with predetermined breaking point for on-wall cable
entry, or in enclosures made of stainless steel (top and bottom part are of stainless
steel, the lid is screwed on), vandalism-secure version e.g. for schools, military
barracks, and public buildings.
The CO content of the air is determined by an optical NDIR sensor (non-dispersive
2
infra-red technology). The detection range of this CO
ard applications such as monitoring of residential rooms or conference rooms. Room
ventilation on an as-needed basis, improvement of well-being and customer benefit,
increased comfort as well as a reduction of operating costs by energy conservation
are just some of the benefits of employing AERASGARD
