These load cells are used for checking the stress state in earthfill embankments and for the control of the pressure of earth on structures and foundations.
To obtain a measure with the maximum sensitivity, the cell is very thin (5mm) with respect to the surface (Diameter = 230 mm) and the instrument has the main surfaces free as the measuring transducer is separate.
Total pressure cells have the well known advantages of vibrating wire instruments.
Rectangular section cells are also available for different applications, complete with a device for pressurization after installation (see related datasheet) .
These cells can be equipped with a vibrating wire sensor, electric sensor or strain-gauge for automatic measurement or with a mechanical device for direct manual measurement.
