The external CO2 sensor with its own alarm transmitter, status LEDs and test button is optimized as an accessory for the SCHABUS gas warning devices GX-HS and GX-A1+. Its warning levels and IP54 protection class are based on the Beverage Dispensing Systems Ordinance. For use in the catering industry, this NDIR sensor was designed for an alarm threshold of 1.5% vol. CO2 for pre-alarm, 3.0% vol. CO2 for main alarm.
The detected CO2 concentration is transmitted to the warning device via an analog voltage, which can then switch a potential-free changeover relay when the alarm threshold is reached.
The connecting cable of the sensor can be extended. The following minimum cross-sections apply depending on the length of the cable: Cable cross-section 3 x 0.75 mm²: maximum length 10 m Cable cross-section 3 x 1.5 mm²: maximum length 20 m A high-tech membrane is located behind the housing openings to keep water away from the electronics. Although the sensor is not waterproof, it is not immediately damaged when water splashes from normal cleaning activities hit the sensor.
