Study on a Fiber Optic Sensor for CH4 in Mine

The detection of CH 4 gas is very important for the prediction of fire in mine. In this paper a technology of CH 4 sensor on the disturb mode of optic fiber is introduced. It is showed that CH 4 can be detected by the flow of light energy in optic fiber, which is caused by the disturbing technology....

Summary:The detection of CH 4 gas is very important for the prediction of fire in mine. In this paper a technology of CH 4 sensor on the disturb mode of optic fiber is introduced. It is showed that CH 4 can be detected by the flow of light energy in optic fiber, which is caused by the disturbing technology. The experiments showed that the sensibility and the selectivity for the detection of CH 4 are researched. The optic fiber sensor for CH 4 is simple and reliable and will have wide application in mine safe.
