Abstract

Un transducteur de déplacement équipe un moteur à combustion interne pour surveiller sa rotation angulaire. Un disque rotatif 2 à périphérie crénelée tourne avec le moteur, et des première et seconde bobines 11 et 13 montées sur le moteur et espacées l'une de l'autre sont couplées inductivement de telle sorte que, lors de la rotation du moteur, les créneaux du disque interrompent le couplage. Une des bobines reçoit une oscillation électrique 16, et induit dans la seconde un signal de sortie. Des organes sensibles au signal de sortie 19 délivrent un signal de commande lié à l'amplitude moyenne de sortie, et un comparateur 22 compare l'amplitude de crête du signal de sortie au signal de commande de façon à indiquer le début et la fin des interruptions. Application notamment aux allumages électroniques.
