Abstract

Capteur de détection de liquide, jonction tubulaire, et ensemble de détection correspondants Ce capteur de détection de liquide (20) comprend un substrat étanche (22) qui est étanche à l’eau et électriquement isolant, un élément absorbant (28) qui est perméable à l’eau et qui est électriquement isolant, et deux fils (36) électriquement conducteurs, logés entre le substrat étanche et l’élément absorbant et disposés à l’écart l’un de l’autre sur toute leur étendue. L’élément absorbant s’applique sur une face (32) du substrat étanche. La face du substrat étanche définit une zone de bord (34) qui est une zone dépourvue d’élément absorbant. L’élément absorbant est adapté pour absorber de l’eau, de sorte que l’eau absorbé créé un pont électrique entre les deux fils. Figure pour l'abrégé : Figure 1
