Standard Type (VW) | Model 4800
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 oil. Changing earth pressure squeezes the two plates together causing a corresponding increase of fluid pressure inside the cell. A vibrating wire pressure transducer converts this pressure into an electrical signal which is transmitted to the readout location.
Standard Ranges¹
|
70, 170, 350, 700 kPa; 1, 2, 3, 5, 7.5, 20 MPa
|
Over Range
|
1.5 × rated pressure
|
Resolution
|
0.025% F.S.
|
Accuracy²
|
±0.1% F.S.
|
Temperature Range¹
|
−20°C to +80°C
|
Height × Diameter¹

¹Other ranges and sizes available on request.
²Transducer accuracy established under laboratory conditions.
Total system accuracy (pressure transducer + pressure cell) is subject to site-specific variables.
*Please Note: Models are also available (3500 Series) with semiconductor pressure transducers to enable measurement of dynamic pressures (please contact GEOKON, INCORPORATED for details).
