Abstract

L'invention concerne un ensemble de mesure pour la détection d'une rotation entre un premier élément de machine (2) et un deuxième élément de machine (3). L'ensemble de mesure selon l'invention comprend un capteur sur roue (10) solidaire en rotation avec le premier élément de machine (2), un capteur absolu (11) solidaire en rotation avec le premier élément de machine (2), un capteur incrémental (27) solidaire en rotation avec le deuxième élément de machine (3) et un capteur absolu (28) solidaire en rotation avec le deuxième élément de machine (3). Le capteur sur roue (10) présente dans la direction circonférentielle une séquence alternante d'évidements (16) et de segments (17). Le capteur absolu (11) est fixé au capteur sur roue (10) et marque une position circonférentielle du capteur sur roue (10). Le capteur incrémental (27) balaie le capteur sur roue (10) et génère un signal incrémental. Le capteur absolu (28) balaie le capteur absolu (11) et génère un signal absolu.
