摘要
本文从液压力大小与钢管外径变形量成正比的概念出发，提出了采用变间距式电容传感器测量液压力。不需开测压孔，并对该测压仪的机械部分进行了设计计算，对误差进行了分析，说明该测压仪适合于工程机械和矿山机械液压系统的故障诊断测试。图３，表２，参３。
This paper has studied out a method for measuring hydraulic pressure by the capactive sensor in terms of the idea that the hydraulic pressure is direct ratio with outer diameter deformation of the steel tube. The mechanical part of the pressure meter is designed and the error is analysised. This paper proved that the pressure meter can be used to diagnose the fault of the hydraulic system of the minenral and construction machineries.3figs.,2tabs., 3refs.
