摘要

Abstract: This paper presents a fiber-optic temperature measuring system which can be used for measuring the temperature in many occasions. The system is of reflective type and composed of thermostatic bimetal-plate, lever-piston framework, optical grating and optical fiber probes. When the temperature changes, the thermostatic bimetal-plate deforms. Through lever-piston framework, the optical grating produces displacement in the upright direction. Thus the change of the temperature is transformed into the upright displacement of the optical grating. Optical fiber probes are used for detecting the number of streak lines of the optical grating's displacement depending on the change of temperature. The detected signal can be transmitted to the control center through optical fiber cable up to distance of 1km. The measurable range of this system reaches 100 degrees C with accuracy of $POM 0.2 degrees C. !3
