Application of Fiber Optical Sensor in Thickness Measurement of Mechanical Seal

Abstract:

Due to film thickness is one of important parameters which has great influence on the performance of mechanical seal, the accuracy of thickness measurement is significant on mechanical seal condition monitoring and performance study. Some limitations were faced when common sensors were used under water of seal face. As new type sensor, FOS has many advantages such as smaller diameter, higher sensitivity, better anti-jamming ability, larger applicable scope than common sensors. In this paper, an enclosed and rotatable calibration test-bed was designed to imitate seal structure by which the feasibility and specifications of FOS application to measuring the seal film thickness had been discussed
