The electronic universal testing machine sensor is an important part of the electronic universal testing machine, but the sensor is damaged due to improper operation or the sensor has been used for a long time, the electronic components are aging and the force measurement is not as accurate as before. The sensor must be replaced.
The sensors of the electronic universal testing machine are calibrated by the manufacturer using special measuring devices before leaving the factory and the testing accuracy is guaranteed. Even if it is the same sensor, the test value is not the same. So if youwant to change the sensor, you need to find the testing machine manufacturer and send someone to recalibrate, otherwise the test result may have a large error compared to the actual value. Cause the test results to differ from previous test results.
The recalibration of the replaced sensor is therefore a point to be considered when maintaining the electronic universal testing machine. In addition, after long-term use of the sensor, due to the aging of electronic components, it also needs to be recalibrated, and the sensor needs to be recalibrated about every two years.
