CGEO-PC1/PC2 Vibrating Wire Earth Pressure Cell

Description

CGEO-PC1 Vibrating Wire Earth Pressure Cell is used to measure soil pressure in soft foundations such as fills and embankments. The instrument is made of special steel, making it suitable for use in various harsh environments.

CGEO-PC2 Vibrating Wire Earth Pressure Cell is used to measure the contact pressure of fill against retaining wall surfaces or interfaces. The pressure box features an extra-thick backplate to minimize the impact of any point loads.

Applications

Concrete, Embankment and Tailings Dams

Diaphragm or Sheet Pile Wall

Retaining Wall

Operation

The Vibrating Wire Pressure Cell is used to measure total pressure, particularly in earth or rockfill structures.

The Model CGEO-PC1 Pressure Cell is constructed from two thin pressure sensitive plates. They can be positioned in the fill at different orientations so that soil pressures can be measured in two or three directions. Special armored cables are 

recommended in earth dam applications. 

The Model CGEO-PC2 Pressure Cell is designed to measure soil pressures on structures. The back plate of the cell which bears against the external surface of the structure is thick enough to prevent the cell from warping. The other plate is thin and is welded to the back plate in a manner which creates a flexible hinge to provide maximum sensitivity of changing soil pressures.

The change in pressure is converted by the VW transducer into an electrical signal and may be remotely read using a VW readout or Datalogger
