Abstract
Un dispositif d'alarme de chute de pression comporte un oscillateur 2 monté sur le châssis d'un véhicule à proximité d'une roue, et contenant une bobine 8 et un condensateur 9. Un résonateur 7, monté sur la périphérie de la roue près de la bobine d'oscillation, et possédant une bobine de résonance 5, un condensateur de résonance 6 et un interrupteur 4 qui, en réponse à la chute de pression anormale, fait résonner une énergie magnétique engendrée par la bobine d'oscillation; une partie de traitement de signal et d'alarme 3 détecte une fluctuation de l'oscillation, le signal de sortie est traité pour émettre une alarme. Application notamment à la détection de défaillances des pneumatiques de véhicules routiers.
