Abstract
In this paper, a brief description of evanescent wave fiber optic methane sensor for the detection of methane gas in the range of 0-10% has been given. The Fiber Bragg grating (FBG) based strain sensor for condition monitoring of steel rope has been described. Laboratory model of both the sensors and their results have been enunciated. Fiber optic, being a dielectric, non-metallic, non-sparking, free from electromagnetic interferences is an intrinsically safe media and is ideally suited for the hazardous environment present in mines.
