    USE MOUNTING
    • Self-calibrating sensor with microprocessor control for measuring carbon dioxide concentration 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 V AC/DC low-current electric mains.
    DESIGN  
    • 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 an additional fan speed controller with input 0...10 V, for example, VFED).
    • With stepless control the fan speed is changed in proportion to carbon dioxide concentration changes.
    • The CO2 concentration in the air is measured by means of a non-dispersive infrared analyser (NDIR).
