Die Erfindung betrifft ein System zur Überwachung von Flächen aller Art bezüglich auftretender Feuchtigkeit oder Leckstellen. Das System besteht aus einer Flächenstruktur, die auf den Oberflächen verklebt wird und von einem elektronischen Sensor überwacht wird.The invention relates to a system for monitoring all types of surfaces for moisture or leaks. The system consists of a surface structure that is glued to the surfaces and monitored by an electronic sensor.

Das System besteht aus einem Flächenmaterial aus Vlies, das mit elektrisch leitfähigen Streifen ausgestattet ist. Das Vliesmaterial ist vollkommen eben, kann auf jeder Oberfläche mit handelsüblichem Klebstoff verklebt werden, oder auch in Verbundmaterialien eingebracht werden.The system consists of a nonwoven surface material equipped with electrically conductive strips. The nonwoven material is completely flat and can be glued to any surface using commercially available adhesives or incorporated into composite materials.

Das Funktionsprinzip beruht auf einer gemäß Bild 1 aufgebauten leitfähigen Struktur. Diese Struktur kann durch individuellen Zuschnitt des in Rollen gelieferten Vliesmaterials jeder benötigten Größe und Form angepasst werden.The functional principle is based on a conductive structure constructed as shown in Figure 1. This structure can be adapted to any required size and shape by individually cutting the nonwoven material supplied in rolls.

Die beiden Teile der Struktur werden mit dem elektronischen Sensor verbunden, der eine Teil mit dem Abschluss C des Sensors, der andere Teil mit einem Eingang des Sensors (hier Eingang 1). Der Sensor überwacht die elektrische Leitfähigkeit zwischen den beiden Teilen der Struktur und meldet ein Überschreiten eines am Sensor eingestellten Wertes.The two parts of the structure are connected to the electronic sensor, one part to the sensor's terminal C, the other part to an input of the sensor (here input 1). The sensor monitors the electrical conductivity between the two parts of the structure and reports when a value set on the sensor is exceeded.

Der Aufbau gemäß Bild 2 ermöglichst die Einteilung der zu überwachenden Fläche (F) in verschiedenen Zonen, die jeweils separat von einem Eingang des Sensors überwacht werden. Damit ist die Möglichkeit einer räumlichen Lokalisierung der Leckstelle gegeben. Für große Flächen können mehrere Sensoren verwendet werden. Eine Beschädigung des Systems durch Nägel/Dübel/Schrauben in haushaltsüblicher Größe wird durch den Aufbau des Vliesmaterials ausgeschlossen. Der elektrische Übergang zwischen Flächenstruktur und elektrischen Kabeln zum elektronischen Sensor wird durch Kontaktfedern oder selbstklebenden Kontaktpads realisiert.The structure shown in Figure 2 enables the area to be monitored (F) to be divided into different zones, each of which is monitored separately by a sensor input. This makes it possible to spatially localize the leak point. Several sensors can be used for large areas. Damage to the system by household-sized nails/dowels/screws is ruled out by the structure of the fleece material. The electrical transition between the surface structure and electrical cables to the electronic sensor is realized by contact springs or self-adhesive contact pads.
