Abstract

Dispositif permettant de détecter toute variation de vitesse relative entre plusieurs pièces en mouvement de rotation. Il comprend des capteurs transformant des vitesses de rotation en fréquence/tension, des moyens d'intégration d'équilibrage, de comparaison de ces tensions de déclenchement d'alarme réglable et éventuellement d'amplification. L'invention peut être utilisée comme instrument de sécurité détectant : - un éventuel dégonflage de pneumatique monté sur véhicule (poids lourds, automobiles, avions, etc.); - tout écart de synchronisme entre plusieurs arbres en mouvement de rotation.
