Abstract

Détection électrique de la situation d'une pièce. Le dispositif comporte : une enveloppe 1 hermétiquement close formant ampoule; au moins deux éléments 2, 3 conducteurs de l'électricité, fixés côte-à-côte à l'intérieur de l'enveloppe et isolés l'un de l'autre ; un organe de pontage 4 propre à se déplacer librement à l'intérieur de l'enveloppe pour établir une connexion électrique entre lesdits deux elements 2, 3 en un point qui dépend de ladite situation; et au moins deux connexions électriques reliant les deux éléments électriques 2, 3 au milieu extérieur de l'ampoule. Application à la mesure d'une position ou d'une accélération.
