Introduction to strain gauge of electro-hydraulic servo tensile tester

Electro-hydraulic servoTension testerIt is an instrument and equipment that is automatically controlled, measured and displayed on the screen by electro-hydraulic servo. Our company has introduced the following information on the strain gauge sensitivity coefficient of the servo tensile tester:

The sensitivity coefficient refers to the ratio of the relative resistance change caused by the strain gauge installed on the part to be tested on the servo tensile tester when it is subjected to unidirectional stress in axial direction to the axial strain on the surface of the specimen caused by this unidirectional stress.

In addition, using servoTension testerWhen the word "thermal lag" will also be encountered. Thermal hysteresis refers to the installation in

The strain gauge of the servo tensile tester, whose test piece can be expanded freely and not affected by external forces, and when the temperature is increased and decreased between room temperature and the limit working temperature, the difference in strain is indicated at the same temperature.
