Automated system for direct shear tests. SOILMATIC
Proetisa’s automated direct shear apparatus is a universal shear system capable of performing the consolidation, drained and undrained direct shear or residual shear stages in a completely automated way.
The system consists of a PC controlled desktop unit with PID control to accurately apply vertical and horizontal loads to the soil sample to be tested.
The standard system is delivered together with 5 kN force transducers for horizontal loads and 5 kN force transducers for vertical loads. Both can be easily replaced by another one with more or less capacity, as needed.
This system can perform the consolidation stage defining as many load increments as desired and in a completely automated way. If desired, you will be able to calculate the appropriate shear velocity for the material to be tested using the consolidation curve.
The system displays real time graphs with force, horizontal and vertical strain values, as well as applied load.
Features and advantages
It is possible to choose between several load capacity ranges from 1kN to 20kN. The system is delivered together with the requested force transducers.
Automated or manual operation of all options. Consolidation, Drained or Undrained Direct Shear tests.
EDS Software displays real time graphs with test data and stores them for later processing and analysis, both graphic and numeric.
EDS Software makes possible to calculate the appropriate shear velocity for the material to be tested after the consolidation stage is completed.
Remote access to control the system wherever you are.
Stored graphs and data can be exported to Excel for later processing.
Word format report creation
Selectable velocity from 0.000005 to 9.8 mm/min. Speed ranges can be increased or decreased.
