Contact Type (Semiconductor, VW) - Model 4810
<p>The Model 4810 &ldquo;Fat Back&rdquo; Pressure Cell is intended to measure contact earth pressures on the surface of concrete or steel structures. The cell has an extra thick backplate to minimize any point loading effects. &lsquo;Ears&rsquo; on the cell ...
Granular Soil Type (Semiconductor, VW) - Model 4815
<p>The Model 4815 Pressure Cell uses two thick plates welded together at a flexible hinge that helps provide a more uniform pressure distribution, which effectively reduces the severity of point loading when used in granular materials. As with the other models ...
Jackout Type (VW) - Model 4820
<p>The Model 4820 Jackout Pressure Cells are used to measure earth pressures on slurry walls. They are designed to fit inside a plate which is pressed against the side of a slurry wall excavation using a hydraulic jack arrangement. This method of installation ...
NATM Style Shotcrete Stress (VW) - Model 4850
<p>The Model 4850 NATM Style Shotcrete Stress Cells are designed for the measurement of tangential (4850-1) and radial (4850-2) stresses in shotcrete tunnel linings. The cells consist of two rectangular steel plates welded together around the periphery with ...
Push-in Type (VW) - Model 4830
<p>The Model 4830 Push-In Pressure Cell is designed to be pushed in place for the measurement of total pressures in soils and earth fills. Where effective stress is required, the cell is fitted with an integral piezometer. A thread is provided on the end of ...
Standard Type (Semiconductor, VW) - Model 4800
<p>The Model 4800 Earth Pressure Cells are designed to measure total pressure in earth fills and embankments. All cells consist of two circular stainless steel plates welded together around their periphery and spaced apart by a narrow cavity filled with de-aired ...
