利用惠斯通电桥测液位
Using Wheatstone Bridge to Measure Liquid Level
摘要
Abstract
Wheatstone bridge can accurately measure the resistance. This paper presents a design plan of experimental devices featuring the change of the liquid level into the change of the potentiometer resistance, and then deduces the relationship between the liquid level and the potentiometer resistance, and finally measures the liquid level for experimental verification by using Wheatstone bridge to measure the resistance change. The measured data show that the means of measurement is a viable method of measuring the liquid level.关键词
