Bishop and Wesley Triaxial Testing Device
This high-quality stress path triaxial system is a fully automatic system consisting basically of a Bishop & Wesley cell which controls stress directly on the sample, three volume pressure controller(VPC), an 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 the keyboard controller (volume pressure controller), 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 etc.
