Constant Pressure System - Air/water

The air/water constant pressure system in a triaxial test system is used to apply and maintain a stable confining pressure around the soil sample, which is crucial for conducting triaxial tests. Used in applying Confining Pressure and maintaining Pressure Stability. A consistent confining pressure is essential for accurate measurement of stress-strain relationships and other soil properties. By keeping the confining pressure constant, the system aids in analyzing the effective stress when combined with pore pressure data (from a pore pressure measurement device). This combination provides insight into the strength and deformation characteristics of the soil sample under controlled stress conditions.
