Details• Sisgeo Hydraulic Pressure Cells designed to measure stress in mass concrete or placed at the interface between the structure and the wall of excavation.
• The pressure pad consists of two steel plates welded together around their periphery and spaced apart by a narrow cavity saturated under vacuum with de-aired oil which guarantee maximum rigidity.
• A length of high-pressure rilsan tubing connects the cavity of the pressure pad to the pressure transducer.
• A repressurizing device is available for expanding the cell after the concrete has cured.
• Readings are obtained with portable readout units or dataloggers.
