Tips: What is a strain gauge?

Strain gauges are object strain used to measure dynamic sensors. Indirectly using strain measurement, they can also be used for stress measurement and load cells.

When the stress inside the structure under test changes, the strain gauge feels the deformation simultaneously, and the deformation is transmitted to the vibrating string through the front and rear end holders to transform it into a change in the stress of the vibrating string, thus changing the vibration frequency of the vibrating string. The electromagnetic coil excites the vibrating chord and measures its vibration frequency. The frequency signal is transmitted to the reading device through the cable, and the internal strain in the structure under test can be measured. At the same time, the temperature value of the buried point can be measured simultaneously.
