Load sensor diagram

The AC servo motor has a built-in displacement measurement system for measuring the displacement of the beam, and can also approximately replace the deformation of the sample (the beam is thick enough, the lead screw is double nuts, and the system gap is eliminated).

For some metal materials, the testing machine is equipped with an electronic extensometer to measure the deformation of the sample. The double collet of the extensometer holds the two points of the sample marker distance and measures the separation distance between the two points of the sample marker distance in real time, that is, the deformation of the sample.

For non-metallic materials with large deformation, the displacement of the beam can be used to replace the deformation. When you need to measure the deformation accurately, you can also choose a special large deformation extensometer.
