Abstract

Die Erfindung betrifft eine Kontroll- und Überwachungseinrichtung zur Vermeidung von Schäden durch Überhitzungen bei flexiblen, textilen Flächenheizelementen, die aus mindestens zwei sich gegenüberliegenden Kontaktleitern (3.1, 3.2) aus elektrisch leitfähigen, unisolierten Fasern oder Drähten, zwischen denen mehrere Heizleiter (8) verlaufen, welche mit den Kontaktleitern (3.1, 3.2) und einer Strom-Spannungsquelle elektrisch leitend verbunden sind, und aus einem Grundmaterial bestehen. Dabei ist mindestens ein elektrischer Zusatzleiter (1) entlang mindestens einem Kontaktleiter über die Heizleiter (8) geführt, wobei der Zusatzleiter (1) mit einem Überzugsmaterial elektrisch isoliert und mit einer elektrischen oder elektronischen Auswerteschaltung (11) verbunden ist, dass das Überzugsmaterial einen Schmelzpunkt oder Erweichungsintervall aufweist, das oberhalb der üblichen Heiztemperatur des Flächenheizelementes aber unterhalb einer zulässigen thermischen Grenztemperatur der umliegenden Materialien und des Grundmaterials (12) liegt, wobei im Falle einer Überhitzung das Überzugsmaterial schmilzt und die Heizleiter (8.1, 8.2) mit dem Zusatzleiter einen elektrischen Kontakt bilden, über den für die Kontrolle der Überhitzung ein Strom zur elektrischen oder elektronischen Auswerteeinheit fließt, die mit der Strom-Spannungsquelle verbunden ist.

The invention relates to a monitoring and control device for preventing damage caused by overheating in flexible, textile Flächenheizelementen consisting of at least two opposing contact conductors (3.1, 3.2) of electrically conductive, uninsulated fibers or wires, between which a plurality of heating conductors (8) extend, which are electrically connected to the contact conductors (3.1, 3.2) and a current-voltage source, and consist of a base material. At least one additional electrical conductor (1) is led along at least one contact conductor via the heating conductors (8), wherein the additional conductor (1) is electrically insulated with a coating material and connected to an electrical or electronic evaluation circuit (11), that the coating material has a melting point or softening interval, which is above the usual heating temperature of the Flächenheizelementes but below a permissible thermal limit temperature of the surrounding materials and the base material (12), which melts in the case of overheating the coating material and the heating conductors (8.1, 8.2) with the additional conductor an electrical contact form over which flows to control the overheating a current to the electrical or electronic evaluation unit, which is connected to the current-voltage source.
