Abstract

Appareil de détection de particules électriquement conductrices aimantables dans un milieu fluide non conducteur. Il comprend un dispositif de détection produisant un flux magnétique sur un trajet s'étendant entre deux électrodes 21, 23 séparées isolées électriquement l'une de l'autre et pouvant être reliées à un circuit de signalisation d'un état dans lequel un trajet électriquement conducteur est formé entre les deux électrodes. Les lignes de force 20 de ce flux s'étendent d'une électrode à l'autre sensiblement suivant des lignes droites. Applications notamment aux boîtes de vitesses et transmissions de machines agricoles et de terrassement.
