Advanced Triaxial System

These advanced rock testing plants enables our customers to meet all test requirements in rock or high pressure material testing and research.

The modular constructed system can be configured with different types of hydraulic frames with different load ranges, a variety of test jigs, triaxial cells with different specimen diameters and pressure ranges, pressure controllers, different sensors with attachments, advanced software packages and further accessories to suit your specific testing needs. The systems are capable to test variety range of materials from soft sandstone to high-strength brittle rock or building materials.

As example different jigs and attachments for performing uniaxial compressive strength, triaxial strength, post failure, bending, indirect tensile, direct tensile, fracture toughness, creep, flexural and cyclic loading tests are available.

 


  • Fitted frame sizes and load ranges from 500 to 10.000 kN with different actuators for each test requirement
  • Dynamic high speed closed-loop control of load, displacement, position and volume or flow
  • Expandable real time high resolution data acquisitionand closed-loop control system up to 21 bit with unlimited number of control axis and sensor channels
  • Different types and ranges of high quality transducers for external or internal on-specimen use like strain measurement, wave velocity, acoustic emission and electrical impedance measurement are available
  • Flexible controlling software for nearly unlimited test procedures of all uniaxial, triaxial or polyaxial test applications with pore pressure and permeability
  • Different types and ranges of high quality transducers for external or internal on-specimen use are available, such as strain measurement, wave velocity, acoustic emission and electrical impedance measurement.
  • Advanced high quality hydraulic power packs with high-quality noise protection, different emergency functions or cyclic test procedures
  • Digital setting of PID parameters to test parameter optimization and tuning
  • Freely programmable test stages with interactive, calculated parameter and test procedures
  • Real-time graphics with zoom and freeze functions for printer output at any time
