Abstract

Un détecteur de bris pour une goupille de cisaillement ayant un trou central, comprend un élément électriquement conducteur formant une boucle allongée s'étendant sur une longueur du trou de la goupille et ayant des bouts supérieurs définissant des surfaces de contact l'un près de l'autre. Un élément électriquement isolant s'étend dans la boucle, pour empêcher le conducteur de se court-circuiter. Des câbles d'alimentation sont connectés respectivement aux surfaces de contact et sont dotés de connecteurs facilitant la connexion du détecteur de bris à d'autres détecteurs de bris ou à un panneau d'alarme. Un corps électriquement isolant supporte de manière amovible les éléments du détecteur dans le trou de la goupille. Un circuit d'identification ayant un voyant lumineux connecté entre les surfaces de contact et faisant saillie à une extrémité supérieure du corps permet de signaler une rupture de l'élément conducteur provoquée par le bris de la goupille.
