Testing system of hydraulic tester

The utility model discloses a testing system of a hydraulic tester. The testing system comprises a hydraulic sensor, a displacement sensor, a data acquisition and processing unit and a display unit, wherein the hydraulic sensor is arranged at an oil inlet pipe of a working oil cylinder of the hydraulic tester; the displacement sensor is arranged between a big cross beam and a small cross beam of the hydraulic tester; the data acquisition and processing unit is respectively connected with the hydraulic sensor and the displacement sensor; and the display unit is connected with the data acquisition and processing unit. According to the testing system of the hydraulic tester, the hydraulic sensor and the displacement sensor have relatively high measurement precision; and meanwhile, oil pressure signals acquired by the hydraulic sensor and displacement signals acquired by the displacement sensor are processed by the data acquisition and processing unit and then directly displayed in the display unit, so that manua
