電子萬能試驗機形變測量標準

Standard for deformation measurement of electronic universal testing machine

通過形變測量裝置來測量，它是用來測量試樣在試驗過程中產生的形變。

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

該裝置上有兩個夾頭，經過一系列傳動機構與裝在測量裝置頂部的光電編碼器連在一起，當兩夾頭間的距離發生變化時，帶動光電編碼器的軸旋轉，光電編碼器就會有脈沖信號輸出。再由處理器對此信號進行處理，就可以得出試樣的變形量。

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.
