Earth Pressure Cells

Model SIS-1100 Series Earth Pressure Cells are used to measure total pressure in soils and embankments, at the interface of two different materials or measurement of stress in concrete. They are also used for measurement of contact pressures on retaining walls, buildings, bridge abutments, tunnel linings etc.

The Pressure Transducer consists of a rigid cylindrical housing having inside it with vibrating wire sensor with the resonant frequency of vibration of a tensioned steel wire is proportional to the strain or tension in the wire. This fundamental relationship is utilized in a variety of configurations for the measurement of pressure. Vibrating wire sensors are well known for their long term stability.
