“Fat Back” Pressure (Semiconductor, VW)

The Model 4810 “Fat Back” 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. ‘Ears’ on the cell assist in holding the cell to concrete forms or to retaining walls during installation.*
