Stress Path Bishop & Wesley Triaxail Testing System

This high quality stress/path triaxial system is consisting basically of a Bishop & Wesley cell, three pressure/volume controller, internal submersible load cell to measure axial load, a pressure transducer to measure pore water pressure and a linear displacement transducer to measure vertical displacement.

Thanks to the integrated software and also keyboard controller (pressure/volume system), the operation of the device is very user-friendly. Exchangeable, pre-calibrated measuring sensors guarantee high accuracy over a wide measuring range.

All the tests are running under PC control like stress path, K0, slow cyclic.

Options:

  • Local strain measurement
  • Unsaturated testing system
  • Bender element test

 


  • An improved Bishop & Wesley triaxial samples with pedestal, top cap
  • Internal submersible load cell to measure and closed-loop control of axial load
  • Pressure transducer to measure pore water pressure and B-value check
  • Linear displacement transducer to measure vertical displacement
  • Automatic pressure/volume controller for closed-loop control of axial stress and strain
  • Automatic pressure/volume controller for cell pressure control and back pressure control
  • Optional advanced data acquisition system for additional transducer
  • A complete PC with user friendly software enables all kinds of stress paths to control automatic pressure volume systems and to acquire all the sensors
  • All devices include a serial RS232 and Ethernet port
