Abstract

L'invention concerne la mesure des vitesses. Elle a pour objet un dispositif de mesure de la vitesse de rotation d'un organe tournant entraînant un disque 10. Un capteur 14 émet une impulsion à chaque passage d'une encoche 11, 12, 13 du disque. Un compteur 16 compte les impulsions émises par un générateur 18 entre les instants de passage des encoches 11 et 12 à chaque tour du disque. Le résultat du comptage est comparé à des valeurs fixes dans un comparateur 20, lequel est suivi d'un circuit de traitement 22 optimisant la mesure pour les diverses zones de vitesse de rotation du disque 10. Application à la mesure de la vitesse de rotation d'organes tournants à vitesse variable.
