The electric pressure cell PR310 was designed to measure the ground total pressures in order to evaluate the interaction between the ground and the structures above. The instruments consist of a membrane uniformly loaded, which works on the first part of its elasticity curve. The pressure cell is produced in several versions in order to allow versatility to every possible application and montage:

• With hydraulic tube allowing loading the cell, with pressure sensor directly mounted either to the cell or to the tube;
• Without hydraulic tube, with pressure sensor directly mounted to the cell either horizontally or vertically.

Upon request, it can be also supplied a piston in order to have a better contact between the cell and the ground. Great attention was made to the mechanical parts during design and production, allowing the membrane to have high accuracy and the instrument to be robust.
