Earth Pressure Cells

The Earth pressure cells are designed to monitor total pressure in earth fill dams, embankments, and at the interface between structures and soil. Pressure applied to the surface of the pressure cell is transmitted hydraulically to a pressure transducer which can be read with a portable readout or a data logger.
