There are two collets on the device, which are connected with the photoelectric encoder installed on the top of the measuring device through a series of transmission mechanisms. When the distance between the two collets changes, the axis of the photoelectric encoder is driven to rotate, and the photoelectric encoder will have a pulse signal output. Then the processor can process the signal and get the deformation of the sample.
