基于光纤形状改变实现的液位传感器实验

Liquid level sensor based on the change of fiber shape

利用光纤自身形状的变化制作的传感器是一种新型液位传感器.本文介绍了光纤液位传感器的实验原理、光纤尖的制作方法,并利用光纤液位传感器实验系统测量了光纤尖在空气、甘油、酒精和水中不同位置的反射光功率.

The new type of liquid level sensor makes use of the self-change of fiber shape. In this paper, the experimental principle of fiber liquid level sensor and preparation of fiber tip are introduced. By using the experimental system of liquid level sensor, the reflection power is measured when the fiber tip is placed at different position in air, glycerin, alcohol and water.
