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.
