For measuring total stresses in soils
The standard total pressure cell measures total pressure (effective stress minus pore water pressure) and is installed within fills to determine its distribution, magnitude and direction.
They are also available with an extra thick back plate to minimize any point loading effects and avoid any warping of the cell. The “Thick Back” Pressure Cells are used to measure contact earth pressures on the surface of concrete or steel structures.
Sensor outputs include vibrating wire and analogue 4-20mA and can be read with a portable readout or connected to a data logger for automatic data acquisition
