Abstract

L'invention concerne la transmission de signaux vers une machine tournante. Il est décrit un dispositif de transmission de signal numérique pour appareillage tournant, caractérisé par le fait qu'il comprend deux bobines coaxiales à proximité immédiate l'une de l'autre et centrées sur l'axe de rotation de l'appareillage, l'une de l'autre et centrées sur l'axe de rotation de l'appareillage, l'une des bobines étant solidaire du rotor, et l'autre du stator, et une des bobines étant alimentée par un signal à transmettre, et l'autre bobine servant de récepteur.
