光纤液滴传感器实现汽油溶液的鉴别

Differentiating petrol based on optical fiber drop sensor

光纤液滴传感器是利用光纤来监测液滴的增长过程,通过分析随液滴下降过程而变化的光强变化曲线,获得反映液体的物理、化学性质的"光纤液滴指纹图"的测试系统。本文利用光纤液滴传感器测量了不同型号的汽油溶液,同时测量了不同型号的汽油溶液按比例混合后的液滴指纹图,通过对比分析液滴指纹图可以实现汽油溶液的鉴别。

The optical fiber liquid drop sensor is a testing system, which monitors the increasing process of liquid drop to get the FFDT （fiber fingerprint drop trace ） which reflects the physical and chemical performances of liquid sample by analyzing the varieties of the light intensity of liquid drop in the dripping process . Different types of petrol and their mixtures with different mixing ratio are tested using optical fiber liquid drop sensor and the FFDTs are obtained. The conclusion is given that different types of petrol can be differentiated by analyzing the FDTs of them..
