Dynamometrical sensor device, manufacturing process and detection system therefrom

Described herein is a magnetic dynamometric sensing device of the type comprising means (10; 40; 50; 70; 80) for sensing a magnetic field imposed on said sensor means (10; 40; 50; 70; 80) by a magnetisation (M) of a movable structure (32; 42; 52; 72; 82) associated to a source of magnetic field, said sensor means (10; 40; 50; 70; 80) detecting, through variations in said magnetic field, displacements of said movable structure (32; 42; 52; 72; 82) originated by the application of dynamometric quantities (P, A). Said movable structure (32; 42; 52; 72; 82) comprises at least an elastically deformable magnetic part which provides said source of magnetic field.
