Abstract

Dispositif permettant le raccordement électrique isolé d'une électrode sonde métallique dans l'ouverture d'un logement, de préférence une électrode destinée à mesurer le niveau d'un contenu. Le dispositif comporte une électrode à tige métallique et une électrode de garde métallique où sont disposés deux cônes de fermeture séparés l'un de l'autre qui, grâce à la présence de couches isolantes, isolent électriquement et ferment hermétiquement l'électrode à tige par rapport à l'électrode de garde et les deux électrodes par rapport audit logement. Les deux électrodes sont raccordées avec un circuit électronique au moyen d'une connexion isolée.
