Our Products
Our product range contains a wide range of Shotcrete Stress Cell and Total Pressure Cells
Shotcrete stress cells are designed to measure radial and tangential stresses in shotcrete linings in tunnels. This instrument provides the most significant data for determining thickness and stability of shotcrete lining in NATM (New Austrian Tunneling method). These cells consist of two rectangular stainless steel plates, welded together around their periphery and spaced apart by a narrow cavity filled with de-aired fluid and connected by a stainless steel tubing to a pressure transducer. The cell has a length of re-pressurising tube to restore contact between concrete and cell after the concrete has set. Provision of gas discharge tube protects the sensor against surge and lightning.
These are used for measurement of total pressure in earth fills and embankments, at the interface of two different materials or measurement of stress in concrete. Also used for measurement of contact pressures on retaining walls, piles and tunnel linings.
These cells consist of circular stainless steel plates, welded together around their periphery and spaced apart by a narrow cavity filled with de-aired fluid and connected by a stainless steel tubing to a pressure transducer. Provision of gas discharge tube protects the sensor against surge and lightning.
