Elektronisches LeckwarnsystemElectronic leak warning system

Die !Teuerung "bezieht sich auf ein Leekwarnsysteni insbesondere für ffeizöl-Yorratsbehälter. Ein so lches Leckwarngerät muß über Jahre hinaus, möglichst ohne Wartung, funktionsfähig bleiben.

Diese Aufgabe wird neuerungsgemäß dadurch gelöst, indem eine isolierende Schicht auf die Innenseite des Stahltanks aufgetragen wird. Auf diese Isolierschicht wird eine leitende Schicht aufgetragen. Diese leitende Schicht, in Verbindung mit der Stahltanluvand, "bildet dann ein Electrodenpaar, das voneinander durch die dazwischen liegende Isolierung getrennt ist« Ein so ausgerüsteter Stahltank kann dann durch Widerstandskontrolle elektronisch überwacht werden, indem ein transistorisiertes Tiarngerät angeschlossen wird-, das so ausgelegt ist,, daß ein Warnsignal gegeben wird, wenn der Isolationswiderstand zrwischen den beiden Elektroden einen vorbestimmten Wert unterschreitet» Diese Isolationsänderung kommt in der Praxis vor., nachdem die Außenwände durch leuchtiglteitseinflüsse porös geworden ist» Die korro«·* dierenden Flüssigkeiten dringen dann in das isolierende . Material hinein. Um die Möglichkeit zu habeny die Lage der schadhaften Stelle am Tanfc festzustellen soll die leitende Schicht In Bahnen oder Felder unterteilt und so angeschlossen werden, daß der Widerstand zwischen den einzelnen Bahnen oder Feldern und der Tankwand getrennt gemessen werden kann« Die leitende Schicht wird durch eine zweite Isolierschicht von dem Öl getrennt. gchutzansprücheiThis object is achieved according to the invention in that an insulating layer is applied to the inside of the steel tank. A conductive layer is applied to this insulating layer. This conductive layer, in conjunction with the steel tanluvand, "then forms a pair of electrodes that are separated from one another by the insulation in between "That a warning signal is given if the insulation resistance between the two electrodes falls below a predetermined value" This change in insulation occurs in practice after the outer walls have become porous due to the influence of light. "The corrosive liquids then penetrate the insulating one In order to be able to determine the position of the damaged area on the tank, the conductive layer should be divided into tracks or fields and connected in such a way that the resistance between the individual tracks or fields and the tank wall can be measured separately Shift is separated from the oil by a second insulating layer. protection claims 1.)
