ETD10.180 - Ring Shear Tester
ETD10.180 - Ring Shear TesterETD10.180 - Ring Shear Tester
for shear testing on circular samples
The circular ring shear tester ETD10.180 is a laboratory test device for determining the shear strength and residual shear strength of cohesive and non-cohesive specimens. Similar to a direct shear tester, the sample is installed in a shear box consisting of a lower and upper part but this shear box has an annular geometry. After a consolidation phase, the sample is sheared by rotating the lower shear box around the central axis.
- intuitive operation and easy handling with 4,3” touch screen with separate function keys and haptics
- precision electromechanical drive for controlled normal stress generation
- precision electromechanical drive for controlled torsional / shear stress generation
- rugged and functional construction, all surfaces in contact with the sample and all water-swept parts of the shear device are made of stainless steel, incl. porous discs
- testing with constant volume conditions / dilatancy-free testing
- measurement of a external analog signal (e.g. temperature sensor)
- serial interface for PC-controlled testing with data logging; cyclic measurement data logging with GeoDESC software, displaying and transfering to Microsoft EXCEL for advanced evaluation purposes
