TOTAL EARTH PRESSURE CELLS
In stock
TPC-4000 series Total Earth Pressure cells are designed to measure total pressure (effective stress and pore water pressure) in soils and at the interface between structures and the wall of excavation.
Models 4010 and 4020 are designed to measure soil pressures on structures. They are fitted with an extra thick back plate on one side which is placed against the structure so as to avoid any warping of the cell. The other side has a thin plate welded to the back plate which provides sensitive measurement of soil pressures.

PUSH-IN PRESSURE CELL
In stock
A Push-in Pressure Cell, also called Spade Cell, is designed to be pushed into the ground where it can measure total earth pressure and pore water pressure within the soil. It can be used as a site investigation tool to determine the in-situ stress state, both vertical and horizontal, depending on the direction of installation. In addition, it can be used to monitor the change in active and passive pressure around retaining structures (diaphragm walls etc) as well as in tunnelling, and other earthworks. Typical installations are in fine grained cohesive soils, including very soft to stiff clays.
JACKOUT PRESSURE CELL
In stock
VWJPC-4500 Jackout Pressure Cells are used to measure active and passive pressures on diaphragm walls during excavation. They are installed within the diaphragm wall cage to monitor pressure on the walls. Any build-up of excessive pressure can be detected in time for remedial measures to be carried out.
The Pressure Cell itself is constructed of two circular, stainless steel plates welded around their periphery. The space between the two plates is filled with an incompressible fluid. A transducer is connected to this space and measures the pressure exerted on the incompressible fluid.
For measuring total stresses in soils and concrete.
