Abstract: The Abstract Hydraulic pressure gauge is designed by the comprehensive verification device of the hydraulic pressure gauge,and based on cascading verification model.It's discussed the mechanism and the control program of the verification process, such as the efficient and precise generation and control of gas-induced liquid pressure. The technical design of the component which uses gas to induce liquid pressure and the design of automatic verification software structure. After experimental testing, features of the device include higher pressure-generation speed, higher precision and greater stability. It can be realized quick and automatic verification of different hydraulic pressure gauge simultaneously. The equipment can be classified as grade-0.05, and the efficiency increases 5 times as compared with the manual verification.
