The BAPI CO2 Sensor is an accurate and reliable way of incorporating demand controlled ventilation into a building’s HVAC strategy. It measures the CO2 in a range of 0 to 2,000 ppm with a field selectable output of 0-5 or 0-10 VDC.
The non-dispersive infrared (NDIR) technology has been optimized for areas that are periodically unoccupied and features automatic background calibration over a long time period to reduce drift. The sensor is also altitude compensated for long-term accuracy and stability. Changing air pressure, due to altitude or weather patterns, can change the output of most CO2 sensors by as much as 17%. The BAPI unit has a built-in barometric sensor that continuously compensates the output for accurate readings despite inclement weather or the altitude of the installation.
The unit can be ordered as CO2 alone, or with optional temperature sensing, temperature setpoint, occupant override and humidity sensing. The large format display is easy to read and alternates between the measured values (CO2, Temperature or Humidity). The display is also field adjustable between °F or °C and all the displayed values may be turned on or off by an HVAC technician.
Optional indication of the CO2 level as “Good, Fair or Poor” is available as a three-color LED on the unit or as an arrow on the display.
