Stress Path Triaxial Testing System

The Stress Path Triaxial Testing System is based on the TKA designed stress path triaxial rheological testing software, TKA stress path triaxial rheological cells and 3x3MPa/250cc standard pressure/volume controllers. Three of these pressure controllers link the computer to the test cell as follows:
one for axial strain and axial displacement control
one for cell pressure control
one for setting back pressure and measuring volume change

Large monochromatic graphic display 192*64 pixel to view data recording in real time. Meanwhile, testing data can be saved through the spreadsheet software.
Features:

1. Adjust the area automatically. The system can automatically work out the sample average area by the volume change and axial displacement, and is widely used in all the controlling calculation. (The average area is defined as the cross-sectional area of the cylinder which has the equal height and volume to the deformed specimen)
2. Pore pressure is measured by the pore pressure sensor which connects with the pedestal
3. Resolution ratio for the test of volume change is 1mm3
4. The underwater load cell can eliminate the friction force of axial load cell and pressure chamber
5. Axial displacement is measured by 2 way independently: measured by sensor directly, indirectly by the volume change of the cell
