Abstract

Système d'alarme signalant la présence d'humidité, doté d'un système de détection s'étendant sur une surface à surveiller, ainsi que d'un dispositif de détection recevant des signaux du système de détection. Ledit système de détection comporte des conducteurs séparés dans l'espace en contact conducteur avec une matière absorbant l'humidité. L'emplacement de la fuite est déterminée par interrogation sélective de paires de conducteurs. Les conducteurs peuvent être disposés dans une matrice orthogonale (A1...X1; A2...X2), chaque conducteur (10, 11) étant associé à une bande (12, 13) absorbant l'humidité.
