CO2DT and CO2DT-R are CO2-transmitters with patented auto-calibration, intended for duct mounting. The sensing element is mounted in the cover-part of the
casing and the probe is in the shape of a venturi tube with two air channels. The air in the ventilation duct is transported to the sensing element through one half of the probe and then back to the duct through the other half.
Mounting
To ensure proper function, make sure that that the cover is properly fastened and that the cable gland makes a tight seal around the cable. The transmitter should be placed in the air flow direction of the ventilation duct according to the marks on the cover.
Applications
The CO2-level gives a direct indication of the indoor air quality. This information can be used to control ventilation with high precision and improve the air quality. By increasing the supply air only when it is necessary, it is possible to minimise energy costs. CO2DT(-R) can for example be used to control ventilation in residential and office areas.
