Advantages
Large operation range (variable diameters and measuring lengths)
✓ High reproducibility
✓ Application and disassembling also during the test
✓ Conception for mobile tasks (transport box)
Working Principle
The double extension sensor with the desired measuring lenght is applied to the specimen. It is fixed by the springs. At this procedure the precise extension sensors are blocked at neutral position. After the adaption they will be delocked and a zero adjustment (ZERO potentiometer) will be performed. The compression test will be done; before rupture of the specimen the extensiometer should be removed. The removement can be performed even when sample is under load.
