The EPS-30V-S earth pressure cell is used to measure total pressure in the earth fills and embankments. Two stainless steel discs welded around the periphery forms a flexible, circular and flat pressure pad.


The pressure pad is connected to an electron beam welded vibrating wire pressure sensor with a 6 mm diameter x 165 mm long stainless tube. The narrow cavity between the pressure pad and the tube is filled with de-aired fluid. Pressure applied by the earth on the capsule is transmitted through the fluid to the vibrating wire pressure sensor, which converts it into an electrical signal.
