摘要
基于光纤反射式强度调制的机理和双金属片良好的温度特性,提出了一种新型的光纤温度传感器结构,研究了基于这种传感器的智能型光纤温度检测系统。该光纤温度传感器具有现场不带电、动态范围宽、适用范围广、安装方便等一系列优点,检测系统的准确度优于±0.2℃。
A fiber-optic temperature measuring system which can be used for measuring the temperature in many occasions is presented.The measuring system is of reflective type and composed of thermostatic bimetal-plate,lever-piston framework,optical grating and optical fiber probes.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℃ with the accuracy of ±0.2℃.
