THM ENVIRONMENTAL TRIAXIAL TESTING SYSTEM

This high-quality stress path high-pressure temperature-controlled triaxial test system is a fully automatic system that uses an active triaxial cell with a built-in axial loading mechanism (based on Bishop & Wesley cell type) that controls stress directly on the sample. In Addition to the active cell, the system includes three high-pressure volume pressure controllers (VPC), an internal submersible load cell to measure axial load, a pressure transducer to measure pore water pressure, a linear displacement transducer to measure vertical displacement, a lifting mechanism, and temperature controlling unit.

The triaxial cell is made from stainless steel and specifically designed for high-pressure tests under various temperature conditions and has an internal submersible load cell for axial load measurement. This system needs 3 Advanced volume pressure controllers for the axial load (lower chamber), cell pressure and one for back pressure.
