Abstract

DISPOSITIF DE MESURE DE VITESSE A PARTIR D'UN CABLE COAXIAL DE MESURE A L'AME CENTRALE ROTATIVE. LE DISPOSITIF COMPREND UN RACCORD PRINCIPAL 120 PRESENTANT UN EVIDEMENT AXIAL, MOBILE EN ROTATION, ENGAGEE DANS L'EVIDEMENT AXIAL DU RACCORD ET RENDUE SOLIDAIRE DE L'EXTREMITE DE L'AME DU CABLE COAXIAL. LES PIECES 120, 110 SONT PERCEES DE CANAUX 125, 115 PERPENDICULAIRES A LEUR AXE. LE CANAL 115 PEUT VENIR EN ALIGNEMENT AVEC LE CANAL 125 LORS DE LA ROTATION DE LA PIECE CYLINDRIQUE. UNE SOURCE DE LUMIERE FIXE 140 ET UN ELEMENT PHOTOSENSIBLE FIXE 150 MONTES DANS UN CIRCUIT ELECTRONIQUE PERMETTENT DE DELIVRER DES IMPULSIONS A CHAQUE RECEPTION DE RAYONNEMENT LUMINEUX DUE A LA MISE EN ALIGNEMENT DES CANAUX 115, 125. APPLICATION NOTAMMENT AUX MESURES DE VITESSE ET DE DISTANCE PARCOURUE SUR LES VEHICULES AUTOMOBILES.
