Abstract

La présente invention concerne les dispositifs chargés d'assurer la détection du degré d'humidité du linge contenu dans une machine de séchage en vue d'en commander le fonctionnement automatique. Le dispositif objet de l'invention comporte au moins une électrode interne isolée par rapport à la paroi conductrice du tambour tournant de la machine afin de permettre l'établissement d'un pont résistif à travers la masse du linge humide, le dispositif étant caractérisé par le fait qu'il comporte essentiellement un circuit oscillant parallèle pourvu d'une part de moyens de couplage électromagnétique et d'adaptation électrique avec ledit pont résistif et, d'autre part, des moyens électroniques créant aux bornes dudit circuit oscillant une impédance créant aux bornes dudit circuit oscillant une impédance négative d'entretien dont la valeur absolue est réglable par un potentiomètre de consigne.
