The carbon monoxide sensor for mining (hereinafter referred to as the "sensor") is mainly used to monitor the concentration of carbon monoxide gas in coal mines. It can continuously and automatically convert the carbon monoxide concentration in the mine into a standard electrical signal and transmit it to the matching equipment, and has the functions of on-site display of concentration value and over-limit sound and light alarm. After being online inspected by the national explosion-proof inspection agency, the sensor can be matched with various types of domestic monitoring systems and is suitable for fixed use in mining working faces, return air lanes, goafs, gas extraction pipelines and other places with spontaneous combustion tendencies.
Sensor explosion-proof type: mining intrinsically safe type; explosion-proof mark: "Ex ia ⅠMa".

Range: (0~500)ppm;

Response time: ≤35s;

Intrinsically safe design, EMC protection design;

Waterproof and dustproof design reaches IP65 protection level;

Four-level alarm time and alarm point: can be set locally or by system.

Working voltage: (9~25V)DC;

Working current: ≤50mA;

Output signal: RS485 as the main signal, supplemented by multiple segmented frequencies.
