Product Code : DYNTTS-5

 The Advanced Dynamic Triaxial Testing System (DYNTTS) is a high-end testing apparatus combining a triaxial cell with a dynamic actuator capable of applying load, deformation and stresses at up to 5Hz. 

The axial axis is screw-driven from an integral base unit housing the motor drive. Axial force and axial deformation are applied through the base of the cell. 

Key features Benefits to the user
High accuracy electro-mechanical control: The DYNTTS system is capable of very small strain static tests through to large strain dynamic tests.
Interchangeable load cells: Allows user to accommodate very soft to very stiff soils with ranges of 1, 2, 4, 8, 10, 16, 25, 40 and 60kN.
In-built balanced ram (up to 5Hz systems): Keeps cell pressure constant during cycling, meaning a dynamic pressure controller is not required (unless dynamic cycling of cell pressure is required).
Interchangeable pedestals and triaxial extension top caps: Allows testing of 38, 50 and 70mm diameter test specimens in the same cell.
Direct closed loop of axial displacement & axial force: Accurate control in either axial displacement or axial force mode.
