Abstract

L'invention concerne une sonde destinée à indiquer le niveau d'un liquide. Cette sonde comprend une thermistance entourée d'un capuchon métallique placé à la partie inférieure 2 d'un boîtier 1 et coincée par un ressort entre cette partie 2 et le capuchon, un conducteur de masse 10 longeant la surface du boîtier 13 à l'intérieur de la sonde, qui relie le capuchon à la prise de masse et un second conducteur 12 placé contre la surface 13 -également à l'intérieur de la sonde - qui relie la partie inférieure 2 du boîtier, contre laquelle est appliqué le ressort 15, à une autre pièce de connexion 10. Application à la détection du niveau et éventuellement de la température de l'huile d'un moteur de véhicule automobile.
