数字式光纤浓度传感器的研制

Research on a digital fibre-optic concentration transducer

本文介绍了一种新型光纤浓度传感器。该光纤浓度传感器基于被测介质的折射率取决于其浓度和温度的原理 ,采用光纤传光和CCD检测 ,采用PC机进行数据处理和温度补偿 ,具有很高的测量精度。

This paper presents a new photoelectric concentration transducer,which works on the principle of the refractive index of a measured medium to be dependent on its concentration and temperature.It has adopted some new techniques such as optical fibre,CCD,data fusion,etc,thus having a high accuracy,high reliability and very high anti jamming capability.
