Duct Mounting Carbon Dioxide Sensor with 0/10Vdc Output




CO² transmitters can be used in a broad range of applications including air quality monitoring in buildings. CO² concentration levels in buildings are monitored to provide an indication of occupancy and to drive a ventilation control strategy. An effective DCV (Demand Controlled Ventilation) strategy will conserve energy and maintain indoor air quality.



Measurement Range:               0-2000 PPM factory calibrated

Duct Air Velocity:                        0 to 450 meter/min

Temp Dependence:                     0.2% of full scale per ˚C

Stability:                                            < 2% of full scale over the life of the

    sensor (15 years typical).

Accuracy:                                          ± 40ppm +3% of reading @ 22˚C (72ºF)

    when compared with a factory certified reference.

Non-linearity:                                < 1% of full scale @ 22˚C (72˚F)

Pressure Dependence:             0.13% of reading per mm of mercury

Calibration:                                      Sensors will be calibrated at zero and

    span at the factory. Calibration in the field will not

    be required. Sensors will be shipped with ABC

    Logic™ turned on.

Response Time:                             Three minutes typical for a 90% step change at

    low duct speeds.

Sampling Rate:                              Every two seconds, 25% duty cycle

Warm-up Time:                             < two minutes (operational); 10 minutes to

    achieve maximum accuracy.
