S-CO2DT-R

-transmitter for duct mounting

CO2DT-R is a transmitter for measuring carbon dioxide (CO

) concen-

tration in exhaust air. Measuring range 0...2000ppm and relay output.

CO2DT-R is intended for duct mounting.

Technical data

Measuring principle NDIR (Non-Dispersive Infrared

Technology)

Measuring range 0...2000 ppm

Inaccuracy at 20°C < ±(50 ppm + 2% of the measured value)

Temp. inuence typ. 2 ppm / K

Long term stability typ. 20 ppm / year

Time constant < 120 seconds

Warm-up time < 5 minutes

Ambient temperature -5...55°C

Humidity 0...90 % RH non condensating

Protection class IP65 with probe downwards, otherwise

IP20

Mounting

CO2DT-R should be mounted at a place in the duct where it can be

expected to give a representative reading. The transmitter should be

placed at least 4 duct diameters after a bend for minimal turbulence.

Open the front cover by removing the screws on the cover with a screw-

driver.

Start-up

After applying power to CO2DT-R, it will take a few minutes before it

shows correct values.

Calibration

CO2DT-R is factory calibrated before delivery and does not need to

be calibrated at installation.

CO2DT-R is calibrated automatically, which means that manual recali-

bration is not required during the lifetime of the sensor.

EMC emission and immunity standards

This product conforms to the requirements of European EMC stan-

dards CENELEC EN 61000-6-1 and EN 61000-6-3 and carries the

CE mark.
