Abstract

Abstract: We design an online monitoring system for mechanical and electrical equipment based on fiber Bragg grating sensing technology. Test results show that it has better frequency response and repeatability. We apply the system to the vibration monitoring for a turbine and implement realtime and online status monitoring for an electrical and mechanical equipment. Its detection result is basically identical to those of a standard acceleration sensor and a handset speedometer. Longterm application shows that it has higher accuracy and stability.

Key words: vibration, mechanical and electrical equipment, status monitoring, fiber Bragg grating
