Control Hire’s Total Earth Pressure Cell provides reliable measurement of soil pressure and stress distribution in a wide range of civil and geotechnical projects. Designed to capture both effective stress and pore water pressure, it ensures accurate real-time data for excavation stability, retaining walls, embankments, and tunnel linings.
Constructed with corrosion-resistant stainless steel and a hydraulic fluid-filled sensing element, the unit offers long-term stability and precision in harsh environments. It is available in multiple pressure ranges and diameters to suit diverse monitoring needs.
Key Applications
- Pressure monitoring in diaphragm and slurry walls
- Retaining wall stability assessment
