Mine Gas

At present , the catalytic combustion type gas sensors is still used in our country which is the extensive use of underground coal mine gas detection instrument , this kind of sensor slow response, calibration cycle is short, and the apparatus for the selectivity of methane is poor. Thus it can be seen that develop a safe and reliable, selective, high sensitivity of gas concentration measurement system that for mine safety operation, the personal safety and environment protection has a very important social significance and economic significance. Optical fiber sensing monitoring system according to the gas absorption spectrum principle with double light path structure on the mine gas online monitoring the concentration of the gas, has avoid the explosion, dust and so on many special advantages.
