Beschreibung
Zusammenfassung:A device for checking the electrical conductivity of tyres for vehicle wheels comprises: a first electrode (17) configured for resting against a surface of a component of a tyre (2); a second electrode (18) configured for closing an electrical circuit with the component of the tyre (2); a meter (19) operatively connected to the first electrode (17) and to the second electrode (18). The meter (19) is configured for generating a voltage between the first electrode (17) and the second electrode (18) and obtaining an electrical resistance between them. The first electrode (17) has, at least when it is resting against the surface of the component, at least one contact portion (23) more yielding than the component and electrically conductive and configured for copying concavities of the aforementioned surface.
