ABSTRACT:
A strain gauge element in which the compression forces applied by at least one of the pressure members are transmitted to a first surface of the strain gauge by a cross formed by two cylindrical rods, the contact between the strain gauge (or the said pressure member) and the cross being exerted on a generating line of one of the rods (or the other rod) of the cross, permitting the said pressure member to carry out a tilting movement about the said rod (or the other rod).
The reactionary compression forces applied to a second surface of the strain gauge are applied either by at least one cross or by rods.
