RADIAL DISPLACEMENT MAGNETIC DETECTOR DEVICE FOR A ROTOR

摘要

IN THE CANADIAN PATENT AND TRADEMARK OFFICE PATENT APPLICATION entitled : Radial displacement magnetic detector device for a rotor. Inventors : Maurice BRUNET and Jean-pierre JOLIVET Applicant : SOCIETE EUROPEENNE DE PROPULSION The magnetic detection device comprises inductive elements, each one being constituted by a magnetic circuit the cross-section of which inside an axial plane is U-shaped, and a coil situated in a radial plane which constitutes a plane of symmetry for the corresponding magnetic circuit. Each of said inductive elements extends over an arc of circle of about 120.degree. and are distributed in pairs of diametrically opposite elements. The pairs of inductive elements are angularly offset and situated in separate adjacent planes in which are situated the reference rings integral with the rotor.
