Abstract:
In this paper, a multi-parameter optical sensor system for vibration, temperature and strain monitoring is presented. It is based on a hybrid singlemode-multimode fiber optic transducer, where the vibration is detected by means of a fiber cantilever beam and extrinsic coupling of light, while two fiber Bragg gratings measure the temperature and strain. Experimental results show good performance for the monitoring of large electric machines.
