Total Earth Pressure Cell
Total Earth Pressure Cells are designed to measure stress acting on plane surfaces.

Earth Pressure Cells are designed to measure total pressure in earth fills and embankments. All cells consist of two circular stainless steel plates welded together around their periphery and spaced apart by a narrow cavity filled with de-aired oil. Changing earth pressure squeezes the two plates together causing a corresponding increase of fluid pressure inside the cell. The vibrating wire pressure transducer converts this pressure into an electrical signal which is transmitted as a frequency via cable to the readout location.

Pressure Cell is intended to measure contact earth pressures on the surface of concrete or steel structures. The cell has an extra thick backplate to minimize any point loading effects. 'Ears' on the cell assist in holding the cell to concrete forms or to retaining walls during installation
