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 introduces a fiber level test system suitable for flammable and explosive liquid storage tank. Compared with the pressure type fiber optic liquid level sensor, this system achieves on-line all-optical non-electricity on-line detection and its output signal has nothing to do with the light intensity change. Has good stability and anti-interference ability.
