Pressure Cells
Reliable Earth Pressure Cell and Pore Pressure Gauge for Geotechnical & Structural Projects
Proact IMS offers robust and highly accurate Pressure Cells designed for the measurement of soil pressure, rock stress, and contact pressure in geotechnical and structural monitoring applications. Our pressure cells are built to endure buried environments, high-load zones, and dynamic loading conditions, providing real-time data essential for assessing ground stability, foundation performance, and retaining structures.
With a range that includes earth pressure cells, rock stress cells, and contact pressure sensors, we deliver site-proven solutions for critical infrastructure monitoring.
