Abstract

L’invention concerne une turbomachine (10) équipée d’un système (40) de mesure de vitesse de rotation d’un arbre d’un rotor, comportant : - en aval dudit rotor (12, 16), un carter intermédiaire (50), comportant au moins une paroi extérieure cylindrique (52), une paroi intérieure cylindrique (54), et un passage coaxial (56) pour une veine (37) de flux primaire, traversé par un bras radial creux (60), - une roue phonique (62), solidaire de l’arbre, - un capteur (64) à reluctance variable oblong et sensiblement tubulaire, traversant radialement le carter intermédiaire (50) et son bras (60), dont une extrémité active (70) s’étendant à proximité de la roue phonique (62) selon un entrefer (e) déterminé, caractérisée en ce qu’elle comporte un fourreau (76) tubulaire axial sensiblement complémentaire du capteur (64).
