Paper Abstract

The author in the paper fabricates a novel type of chirped fiber Bragg grating (CFBG) vibration sensor with symmetrical push-pull configuration. It is a typical mass-spring system mainly made up of CFBG, steel tube, mass block. A push-pull configuration design makes it have not only high sensitivity but also function of temperature self-compensation. Using CFBG instead of FBG as a sensing element makes its measuring range increase by a big margin. Adopting matching demodulation technology solves availably the problem of demodulation speed. The sensor has excellent sensing properties and been successfully applied to vibration monitoring and fault diagnosis on large rotating machinery.
