Related Factors Affecting The Tensile Testing Machine

1. A sensor. Because the quality of the sensor determines the accuracy of the Tensile Testing Machine and the stability of the force measurement, if the accuracy of the strain gage is not high or the anti-aging ability of the rubber for the fixed strain gage is not good or the material of the sensor is not good, the accuracy of the sensor will be affected precision and service life.

2 Ball screw, because the test data will be made in the future if there is a gap between the screw, it will directly respond to the maximum deformation and elongation after the test. The friction is relatively large and the service life is short.

3 transmission systems, some electronic tensile machines on the market currently use reducers, and some use ordinary leather to drive, the main drawbacks of these two transmission methods: the former requires regular lubrication, the latter can not guarantee the synchronization effect of the transmission test results.

The measurement and control system of the Electronic Tensile Test Machine, the current measurement and control system of some electronic tensile machines on the market is controlled by 8-bit single-chip microcomputer, the sampling rate is low, and the anti-interference ability is poor. In addition, the AD converter has the number of bits of the AD converter. If the resolution is low, then the measurement will not be accurate.
