Carbon monoxide concentration sensor CSCO-2 is a stationary device for measuring carbon monoxide content in explosion hazard areas in underground coal mines. It cooperates with telemetric central station CST-40(A) through analogue station CSA-1 and CSA-2. It may also cooperate with other devices provided that the terminal of the feeder-measurement line is compatible.
The CSCO-2 sensor has two measuring ranges: 0-200 and 0-1000 ppm CO. It is power-supplied from an intrinsically safe source with voltage of 12 V. The measured and processed value of CO concentration is sent to analogue output which generates a signal of 0.4 to 2V. Additionally, by modulating the analogue value, the output may also work in serial digital mode transmission. The output in digital mode has one measuring range of 0-1000 ppm CO and may send (via the CSA-1 or CSA-2 station) the serial number of the sensor and other diagnostic information.
The CSCO-2 sensor is a device of M1 category and may thus be used in all underground mines with possible methane or coal dust explosion hazard.
