Main Features


  • Capability to perform Static (effective stress and stress path), Dynamic and Unsaturated soil triaxial tests
  • Three axis closed loop control for axial load or displacement, cell and back pressure
  • Automatic compensation of cell/back pressure during dynamic stage
  • Nominal operating frequency up to 10 Hz (depending on the test condition) 
  • Complete test automation of all test stages using an high sensitivity closed loop P.I.D. feedback 
  • Dynamic load/displacement options: up to ±25 mm with ±5 kN double-effect actuator
  • Available upgrade for Bender element testing and Local strain measurement
  • Standard and user defined wave shapes also derived from in situ measurements (from violent earthquakes to sedate ocean waves)
  • Test set-up by unique programmable Multi stage test procedure: during the test run, acces to all controls to expand and modify the stages according to the response of the soil specimen
  • Manual and automatic Emergency air shut-off function

  • tecnical specifications
    • Scroll the table
      • Dynamic load capacity: ±5 kN 
      • Static load capacity: 50 kN ( 100 kN available on request) 
      • Nominal operating frequency: up to 10 Hz (depending on soil and  test conditions)
      • Max diameter sample: up to 150 mm  
      • Max cell and back pressure: depending on max working pressure of air supply
