CO2 Duct Sensors



Automated Logic’s CO2 Duct Sensors are an accurate and reliable way of incorporating demand-controlled ventilation. They measure the CO2 in a range of 0 to 2,000, 0 to 5,000, 0 to 10,000, and 0 to 50,000 ppm with a field selectable output of 0 to 5 or 0 to 10 VDC.


The non-dispersive infrared (NDIR) technology of the “24/7” units has been optimized for areas that are continuously occupied. They feature a dual-channel optical system and three-point calibration process for enhanced stability, accuracy, and reliability.


These units also have continuous automatic air pressure compensation. Air pressure changes from altitude or weather patterns can affect the output of CO2 sensors, even putting them outside of their specified accuracy. These units have a built-in barometric sensor that continuously compensates the output for accurate readings despite the weather or the altitude of the installation.


The unit samples duct air using an aspiration tube.


Optional indication of the CO2 level as “Good, Fair or Poor” is available as a 3-color LED for 0 to 2,000 ppm range units.
