The pressure cell is designed to measure total pressure in earth fills and embankments; as well as pressure on the surface of retaining walls, buildings, bridge abutments, and tunnel linings. Pressure Cells are also used to measure stress in mass concrete. Encardio-Rite is the world’s leading manufacturer and supplier of Pressure Cells.
Encardio-rite essentially has six different types of Pressure Cells largely being put into geotechnical monitoring and surveying.
Model EPS-30V-C Concrete Pressure Cell to measure the orientation and the magnitude of total pressure and stress distribution within the dam embankments and the interface of soil and concrete.
The Model EPS-30V-I Soil and Rock-Concrete Interface Pressure Cell to determine the contact pressure on retaining and diaphragm walls, piers and abutments.
The Model EPS-30V-J Jack Out Pressure Cell to measure the total stress i.e. the effective stress due to the soil together with the pore water pressure in the voids between soil grains. It is suitable for measuring static or slowly varying stresses only.
The Model EPS-30V-S Earth Soil Pressure Cell to measure pressure on and within the lining of underground excavations. It also monitors stress in the rock walls of unlined caverns and tunnels.
The Model ESC-30V and Model ESC-30V-R Shotcrete-Concrete Stress Cell to measure radial and tangential stresses in shotcrete tunnel linings. They are often used in conjunction with the EDS-80 tape extensometer and EDS-64 borehole extensometer to measure the performance of the lining and to determine whether the lining is thick enough to maintain stability.
The applications of pressure cells include:
