BPC-series Balanced passive triaxial cell

Description


The BPC-series balanced passive triaxial cells are designed for specialized compression testing of rock samples under consistent confining pressures and axial compressive forces. To apply the axial forces, a separate external load frame is necessary. One standout feature of the cell is its self-adjusting axial load ram, which neutralizes the upward force generated by the internal cell pressure. This not only spares the external load frame from bearing the cell's pressure load but also decreases the overall capacity needed from the load frame to achieve the desired deviatoric stress. This design also eliminates any fluctuations in confining pressure during axial loading. Within the cell, rock samples are encased in a Teflon sleeve and flanked by hardened steel end caps. This assembly is then submerged in oil under pressure for confining the specimen. Integrated electrical connectors at the base of the cell make it possible to install a range of internal monitoring instruments, including devices for measuring axial and radial deformations, ultrasonic platens, and various specialized transducers. The cell's design incorporates both upper and lower fluid ports for conducting pore pressure tests, an integral part of its architecture. It comes equipped with a low-friction loading piston, and customization options include different sizes of platens, pistons, and additional electrical connectors for specialized testing. A heating system can also be added to the cell upon request.
