VW Earth Pressure Cell
VW Earth Pressure Cell is crafted for the precise measurement of total pressure within earth fills and embankments. It comprises two circular stainless steel plates, welded around their edges, housing a narrow chamber filled with de-aired oil. Variations in earth pressure compress the plates, increase oil pressure accordingly. This pressure change is detected by a vibrating wire pressure transducer, connected to the plates through a short length of steel tubing.
