摘要
文中介绍了一种由光纤、线阵ＣＣＤ 及浮子组成的液位测试系统。该系统在实现了现场全光无电在线检测的同时，使输出信号与环境光干扰无关，与光源信号漂移无关，且动态范围大，灵敏度高，稳定性好，适合易燃易爆液体贮罐的现场应用。
This paper describes a liquid level measuring system by optic fiber linear array CCD and buoy, The system has achieved that it detects Liguid level signal with light without electric power in the meassuring field. There fore,the output signal has no perturbation motion of environmental light and drift singal of linht source and also a large measuring range,a high measuring sensitivity and stability.Thus it can be applied in arees of storage tank which is easy to explode and burn.
