CO
-transmitter for duct mounting
2
CO2DT-R is a transmitter for measuring carbon dioxide (CO
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. influence
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.
