电子万能试验机形变丈量标准

Standard for deformation measurement of electronic universal testing machine

通过形变丈量装置来丈量，它是用来丈量试样在试验历程中爆发的形变。

It is used to measure the deformation of the specimen during the test.

该装置上有两个夹头，经过一系列传动机构与装在丈量装置顶部的光电编码器连在一起，当两夹头间的距离爆发变革时，发动光电编码器的轴旋转，光电编码器就会有脉冲信号输出。再由处理器对此信号进行处理，就可以得出试样的变形量。

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.
