Abstract

Une sonde de détection d'humidité est utilisée dans une structure de bâtiment pour détecter la pénétration de l'humidité. La sonde est un ruban adhésif plat d'un substrat de matériau diélectrique hydrophobe. Trois ou quatre sondes allongées et parallèles sont fixées à la surface supérieure et une couche protectrice de matériau non hygroscopique et perméable à l'eau est fixée sur deux des conducteurs de sorte qu'ils sont exposés à l'humidité de la surface. Un ou deux des conducteurs sont recouverts par une couche isolante pour empêcher l'accès à l'humidité. Des paires de sondes d'humidité le long de la longueur du ruban pénètrent dans la couche isolante, les conducteurs respectifs et le substrat, et se prolongent dans un élément de construction auquel le substrat a été collé. Un dispositif de guidage de diode permet à une unité de surveillance de surveiller les sondes exposées afin de détecter l'humidité de surface et les conducteurs pénétrés afin de détecter l'humidité dans le composant en inversant la polarité de la tension aux bornes des conducteurs.
