Abstract: Position sensor for a mechanical device, including: an optical emitter arranged for projecting an incident radiation on a positioning track of the mechanical device provided with multiple optical sections; an optical detector arranged for detecting a reflected radiation coming from the positioning track and for generating a corresponding measurement signal; an electronic processing unit arranged for calculating, on the basis of such measurement signal, a reflectance value indicative of the reflectivity of the zone of the positioning track hit by the incident ray so as to distinguish the different optical sections of the positioning track. The position sensor also comprises a signaling module arranged for sending a warning signal as a function of the reflectance value, in order to provide to the user indications relative to the level of deterioration of the optical sections of the positioning track.

Abstract: System for measuring the position of a mechanical member, which comprises an optical detection system and a positioning track arranged on two mechanical members of a mechanical device. The positioning track is provided with a succession of multiple sectors, each of which comprises a first delimitation section and a second delimitation section spaced from each other, and a first identification section and a second identification section which are provided with a different optical contrast with respect to the first delimitation section and to the second delimitation section. In each sector, the first identification section is delimited between the first delimitation section and the second delimitation section. In addition, the length of the identification sections of each sector is different from the length of the identification sections of each other sector of the succession, so as to unequivocally identify the corresponding sector.
