Self-calibrating sensor with microprocessor control for measuring carbon dioxide content in the air within the range from 0 to 2.000 million-1 (parts per million).


The sensor is mounted onto a wall or a mounting box inside the serviced space. The unit is powered from a 24 VAC/VDC low-current electric mains.


DPWQ40200 CO2 sensor has 2 analogue outputs: 0–10 V and 4–20 mA. An analogue output provides for stepless fan speed control (requires an EC motor fan or a frequency drive). With stepless control the fan speed is changed in proportion to carbon dioxide concentration changes. The CO2 content in the air is measured by means of a non-dispersive infrared analyser (NDIR).
