摘要
本文介绍了一种适合于易燃易爆液体贮罐的光纤液位测试系统。与压力型光纤液位传感器相比,该系统在实现了现场全光无电在线检测的同时,其输出信号与光强变化无关。具有很好的稳定性和抗干扰能力。
This paper describes a fibre optic liquid level measuring system.It is applicable to the storage tank that is easy to burn and explode.Compared with a pressure type fibre optic liquid level sensor,this system is independent of the variations in the lighthing power when it has completed the on line detection with light and without electric power in the measuring field.This system is provided with excellent stability and anti jamming capability.
