ACE - Model 1910 & 1920 VW -Earth Pressure Cells

• The cell is installed with its sensitive surface in direct contact with the soil. External pressure acting on that surface is balanced by an equal pressure induced in the internal fluid.
• This pressure is converted by the pressure transducer into a frequency signal to the readout.
• Correct record is provided by sensors, and sensors are operated automatically, within water pressure chamber, it is
• individually inspected, so confidence is guaranteed.
• The pressure transducer is equipped with a temperature device for compensating for temperature variations.

• Stability and reliability in extreme environment
• Not affected by cable length and resistance change, Reproducibility and repeatability are very excellence
• Possible to automatic measurement

The VW earth pressure cells are used to verify design assumption and excess pressure on the structures. They also measure the combined pressure of effective stress and total pressure.

• Collection data to determine the distribution of, orientation of magnitude of total stress o Measurement of the contact pressure on and foundations
• Measurement of total pressure on the structures during heave
• Checking of density of fills in dams
