Description

NextGen offers a variety of Dynamic Triaxial Systems, with capacities ranging from 5kN/5Hz to 50kN/20Hz, designed to meet your specific testing requirements. Whether you're testing small or large specimens, using Bender Elements, or on-sample local strain sensors, our Dynamic Triaxial Systems can be configured to match your needs. The system features a Dynamic Servo Controller that supports up to 8 input channels and various waveforms. It includes adaptive PID control, allowing the system to automatically adjust internal settings to ensure target load and displacement are achieved, even as sample stiffness changes during the test. This ensures consistent, accurate results for dynamic soil testing.

Standard system configurations feature Pressure Volume Controllers for precise Back Pressure and Cell Pressure control. For enhanced cell pressure regulation or dynamic cycling of lateral pressure around the sample, an upgraded Dynamic Cell Pressure Controller is available.

The Clisp Studio software simplifies the entire testing process, covering everything from Saturation to various Consolidation phases (Isotropic, Anisotropic, or K0), Static Loading, Stress Path, and Cyclic Shear (Stress or Strain) tests. With its intuitive interface, Clisp Studio ensures easy setup and efficient execution, streamlining even the most complex geotechnical testing procedures.
