Paper Abstract

A complex sensor of synchronous measurement of temperature and displacement with optical fiber is proposed in this paper. It can be used in the real-time measurement of temperature of turbine and longitudinal displacement of the leaf. The Measured temperature range is 300~800°C and the resolution is 1°C. The measured displacement range is 0~5rnm and the resolution is 0.01mm. The two signals can be discriminated by using four channels of quartz optical fiber and narrow-band filtering. By operation of the ratio between measurement signal and reference signal, the accuracy can be assured. The experiment results show that the sensor presented has properties such as fast response, good repetition stable work and good reliability.
