pendulum CO2 sensor AERASGARD® RPCO2
The RPCO2 air quality sensor detects the CO2 concentration of the ambient air in the range of 0-10000 ppm via a non-dispersive infrared sensor (NDIR) and converts this measured value into a linear output signal 0-10 V or 4-20 mA. The transmitter is simply suspended as a pendulum in the room, which ensures an accurate measurement result in high rooms.
As an option, the air quality sensor has a potential-free changeover contact and a backlit display. There are 3 different scalings (0-2000 ppm, 0-5000 ppm, 0-10000 ppm) which can be selected via DIP switches.
Zero adjustment in relation to the actual ambient conditions can be performed by manual calibration on the instrument. The air quality sensor performs an automatic self-calibration at regular intervals, ensuring a long-term stable CO2 measurement.
