When the diagnostic device is used, the measuring head or the sensor should be removed from the mechanical installation position of the device, and the way of keeping the measuring head or the sensor cable access meter and the pneumatic circuit access device unchanged, and fixing it to the corresponding device On the fixture or bracket, make the measuring contact contact with the measuring surface on the micrometer measuring rod, rotate the differential cylinder on the micrometer, compare the value displayed on the digital micrometer with the indication value on the measuring instrument, and repeat the operation to check the repeatability and linearity. For some measuring heads or sensors with pneumatic push or electromagnet pull-in function, the function of pneumatic push or electromagnet pull-in is used to check the repeatability and the difference is read on the gauge. Rotate the micro-cylinder on the micrometer and move a certain range to compare with the indication on the gauge to achieve the purpose of checking the linearity.
The illustrated device can test the measuring head or sensor away from the original installation position of the device, completely eliminate the cause of the mechanical mechanism of the device and the influence of the cause of the hidden fault of the device on the measurement result of the measuring head or the sensor, making it difficult to distinguish and judge. The technical problems have become very easy.
