Abstract
A device adapted to measure the wear of a ball-and-socket joint. The ball-and-socket joint comprising a first ring, which delimits a spherical housing, a second spherical ring, which is positioned concentrically in the housing of the first ring, and a lining, which is made from an elastically insulating material and is inserted between the second ring and the spherical housing of the first ring. A wear measuring feature includes at least two electrodes provided to be connected to the first ring and the second ring, respectively, or to the lining, so as to form a capacitor structure and a capacitance measuring device for measuring the capacity of the capacitor thus formed. The device further comprises an electronic circuit, which is a resonant circuit including the capacitor, an inductance and a resistance positioned in series.
