<p>The device has a cylinder chamber (41) having parts (47, 50) with variable volume based on displacement of a piston (46). One of the parts with a supply outlet (43) is filled with incompressible fluid. A connection unit connects an end (49) of a control rod (48) with the piston, so that the rod is partially set in the other part not having supply outlet. A control unit (60) controls translation of the rod along longitudinal axis (42) so as to slide the piston in the chamber with predetermined quantity. Cells (11-13) of a tri-cellular probe (10) have walls made of elastic rubber. The incompressible fluid is water and gas.</p> |
