Automatic Triaxial System Manufacturer,Supplier and Exporter in India
Product Code : TVT-STE-10571
The Automatic Triaxial System is a fully automated, computer-ready triaxial testing system that combines a Triaxial Loading Frame and an Advanced Pressure Volume Controller to run the full range of consolidated and unconsolidated triaxial shear strength tests on soil specimens.
How It Works
The Triaxial Loading Frame and Pressure Volume Controller each carry an LCD graphical display and panel keypad, and can be run as part of a computer-controlled system or as stand-alone units. Axial load is measured by force sensors and axial deformation by a high-precision displacement sensor, while a stepper-motor-and-worm-gear drive gives rigid, low-noise, smooth-running platen movement; an over-force protection device automatically stops the machine if the axial force exceeds the load sensor's measuring range. The pressure-volume controller channels are pre-calibrated and can generate confining/back pressure up to 2000 kPa (20 bar), with volume measured to a resolution of 0.001 ml.

Applications
The system runs the standard triaxial shear strength test suite used in geotechnical design: unconsolidated-undrained testing per ASTM D2850 / IS 2720 (Part 11), consolidated-undrained testing per ASTM D4767 / IS 2720 (Part 12), and consolidated-drained testing per ASTM D7181. Results are used to determine shear strength parameters (cohesion and angle of internal friction) for foundation, embankment and slope stability design.

Frequently Asked Questions
What triaxial test types does this system run?
It runs the full range of unconsolidated-undrained (UU), consolidated-undrained (CU) and consolidated-drained (CD) triaxial tests, along with back-pressure saturation and consolidation stages.
What sample sizes does it accept?
It accepts cylindrical soil specimens from 38 mm to 50 mm in diameter.
Can it be operated without a computer?
Yes, the Triaxial Loading Frame and Pressure Volume Controller can each be run as stand-alone units via their own LCD display and keypad, or integrated into a computer-controlled system.
