High cost performance brick pressure testing machine, automatic pressure strength testing machine

The cost-effective brick pressure testing machine (electrohydraulic servo pressure testing machine) is mainly used for the compressive strength test of brick, stone, cement, concrete and other materials, and also for the compressive performance test of other materials. The series of pressure strength testing machine developed by Liangong adopts computer automatic control. The measurement sensors (pressure sensor, displacement sensor, deformation extensometer), servo valve, controller (signal conditioning unit), and servo amplifier form multiple closed loops. realizes the closed-loop control function of the test force, cylinder piston displacement, and deformation of the sample; it has multiple control modes such as constant-rate test force, constant-rate cylinder displacement, and constant-rate strain. And can achieve the smooth switching of the control mode, so that the system has greater flexibility.
