Laser methane sensor for mines is suitable for underground mining working faces, electromechanical chambers, return air tunnels and other locations in coal mines with gas and coal dust explosion hazards. It is used to detect methane concentration and automatically and continuously convert methane concentration into standard electrical signal transmission.

Explosion-proof form: mining intrinsically safe type; Explosion-proof mark: Ex ia I Ma.

[Technical indicators]:

High precision (0-1%: error 0.06%, 1-100%: error 6%)

Full range measurement (0-100% CH4);

Response time is no more than 25s

High reliability, intrinsic anti-interference (no response to non-methane gases);

No intrinsic zero drift, no calibration required during service life;

No external temperature compensation required, linear output of concentration value;

Ultra-fast response time, T90≤25s;

Intrinsically safe design, EMC protection design;

Waterproof and dustproof design reaches IP65 protection level;

Four-level alarm time and alarm point: (0.00%~100)%CH4 can be set arbitrarily, can be set locally or by the system;

Working voltage: (9~25V)DC; Working current: ≤50mA

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