摘要
介绍水银包层光波导作为测温探头的新型光纤温度传感器的探头结构及测温原理。与 80 98单片机相结合 ,实现信号探测及数据处理。这种新型光纤温度传感器结构简单 ,理论分析的相对测量精度可达 0 .0 2 %。实验表明 ,在 2 0~ 10 0°C的温度范围内 ,测量精度为 0 .1°C。对诸如油库等易燃。
This article describes the probe construction and the principle of NOTS,the mercury cladding optical waveguide to be made as its temperature probeWith 8098 microprocessor,we implement the signal detection and data processNOTS has simple construction,its relative precision can attain 002%,and its absolute precision is 01 °C at the temperature range 20~100 °C.It is very important for the temperature measurement of the flammability and explosive place such as oil warehouse and so on
