EVT5 - Laboratory Vane Tester
EVT5 - Laboratory Vane TesterEVT5 - Laboratory Vane Tester
for determining the undrained shear strength of soils acc. DIN 4094-4 and ISO 22476-9
Automatic laboratory vane shear tester for determining the undrained shear strength of soils with a viscous to stiff consistency
- intuitive operation and easy handling with 4,3” touch screen with separate function keys and haptics
- high speed multi-core-system with bus coupling, control loop with 1 ms sampling time
- precision electromechanical drive for generating the shear stress
- robust construction with a very stiff measuring frame and height-adjustable measuring crossbeam
- low-friction bearing of the entire vane drive, so that frictional forces, gear efficiency or bearing friction have no influence on the torque measurement
- torque measurement by precision sensors made in Germany
- tare function for torque measurement
- vane assembly using a clamping device
- large base plate to accommodate nozzles and other sample containers up to Ø 210 mm
- height-adjustable cross yoke, sample containers with a length of up to 400 mm can be used
- practical quick-release device with one-hand operation for holding and fixing the sample container
- 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
- after the test has started, cyclical recording and display of the measured values in the GeoDESC program and online data transfer to Microsoft EXCEL for extended evaluation and presentation purposes
- test evaluation with protocol printout EXL.EVT
