A Novel Method for Non-intrusive Measurement of Pressure in Hydraulic Systems

Yu Feng 1Cui Yuliang 2Jin Shijiu 1Li Zhaoqing 1(Shandong Univ. of Science & Technology Taian 271019) 2(Tianjin Univ.,Tianjin 300072,China)  
This new method is based on the determination of ultrasonic wave velocity of oil inside the pipe. The pressure is a function of the measured velocity value and can be calculated by a single-chip microcomputer. The advantage of the method is that the influence of the thickness of the tube is effectively elimina- ted. Tests of prototype non-intrusive pressure measurement system have shown that it is possible to accurately convert the small change of velocity with the pressure into a direct pressure reading. The system is a useful tool for rapid trouble shooting hydraulic systems.
