The Enviko SK-EP vibrating wire earth pressure cell measures the contact pressure of fill against retaining walls, bedrock and other boundaries, as well as earth pressure within fill, embankments and soft foundations. An extra-thick back plate reduces the effect of point loads. A built-in temperature sensor records the temperature at the installation point.
