The Digital Transformation Of The Material Testing Machine

The material testing machine digitized transformation is installs the sensor on the hydraulic pressure type or the mechanicaltype testing machine, transforms the strength signal into theelectrical signal, through the data acquisition system transformationis the digital signal, thus transforms it the electronic testing machine.The material testing machine digitized transformation may enhance the testing machine the precision, the feasibility, may realize theautomatic computation, the memory, the judgment, the printing, enhances the user the working efficiency, but also may for realize the test chamber microcomputer networking and the hydraulic pressure servo testing machine transforms builds the foundation.The paper mainly after enhances the transformation the testing machine to show the value accuracy and the stability as a goal, carries on the testing machine the digitized transformation.First, through to the material testing machine oil duct system principle of work analysis, pointed out because the pressure transmitter to install the position not to be correct but creates shows the value unstable reason, has discovered the best position which the pressure transmitter installed; then, through the analysis should the variant pressure transmitter structure and the principle of work, had expounded should the variant pressure transmitter characteristic, analyze the influence pressure transmitter output signal stable primary factor, and discussed the temperature with emphasis to the pressure transmitter influence, introduced carried on temperature compensation to the pressure transmitter the method, has chosen the appropriate pressure transmitter in this foundation, and inspected its temperature characteristic and linear through the experiment, Proved it conforms to the requirement completely;...
