Patentiert im Deutschen Reiche vom 15. Juni 1913 ab.Patented in the German Empire on June 15, 1913.
Um das Eindringen von Wasser in geschlossene Räume, z. B. in Schiffe, anzuzeigen, sind Einrichtungen bekannt, bei denen das eindringende Wasser Elektroden, die zunächst durch eine nichtleitende Masse voneinander getrennt waren, leitend miteinander verbindet, wodurch dann ein auf eine Anzeigevorrichtung wirksamer Stromkreis entsteht. Der Nachteil dieser Einrichtungen besteht darin, daß derTo prevent water from entering closed spaces, e.g. B. in ships, to indicate facilities are known in which the penetrating water electrodes that initially were separated from each other by a non-conductive mass, conductively connected to each other, which then creates a circuit that is effective on a display device. The disadvantage of these facilities is that the
ίο Alarmstromkreis erst im Gefahraugenblick durch das eindringende Wasser geschlossen wird, und daß infolgedessen verhältnismäßig große Elektroden, starke Batterien oder überaus empfindliche Anzeigeapparate bedingt werden, welche die Anschaffungskosten sehr erhöhen. Man hat versucht, die nichtleitende Masse, welche die Elektroden voneinander trennt, mit Salzen zu imprägnieren; bei diesem Verfahren, das aber gleichfalls umständlich und nicht zuverlässig erscheint, soll dann durch das Eindringen der Flüssigkeit ein für gewöhnlich zur wirksamen Erregung eines Relais nicht ausreichender, ständig fließender Strom so weit verstärkt werden, daß das Relais ansprechen und den betreffenden Alarm-. apparat einschalten kann.ίο Alarm circuit only in the moment of danger is closed by the penetrating water, and that as a result relatively large electrodes, strong batteries or extremely sensitive display devices are required, which increase the acquisition costs very much. You tried the non-conductive Impregnating the mass separating the electrodes with salts; at this one Procedure, which also seems cumbersome and unreliable, should then the penetration of the liquid usually causes a relay to be energized effectively insufficient, constantly flowing current to be amplified so much that the relay address and the relevant alarm. can switch on the device.
Gemäß der Erfindung ist nun die Einrichtung in einfacher Weise derart getroffen, daß zu einem Widerstand, der im Ruhezustand den ein Relais durchfließenden Dauerstrom auf der für die wirksame Relaiserregung nicht ausreichenden Höhe hält, Elektroden parallel gelegt sind, welche beim Eindringen von Feuchtigkeit durch diese überbrückt werden und dabei die zum Ansprechen des Relais erforderliche Verstärkung des Relaiserregerstromes veranlassen.According to the invention, the device is now made in a simple manner such that to a resistance, which in the idle state the continuous current flowing through a relay at a height not sufficient for effective relay excitation, electrodes parallel are placed, which are bridged when moisture penetrates them and the amplification of the relay excitation current required for the relay to respond cause.
Die Anordnung ist in der beiliegenden Zeichnung beispielsweise dargestellt.The arrangement is shown in the accompanying drawing, for example.
In den zu schützenden Räumen werden Widerstände α untergebracht, zu denen Elektroden b parallel geschaltet sind. Die Widerstände β sind einerseits mit einem Pol der Batterie c, andererseits mit je einem Relais d verbunden. Der Gesamtwiderstand des Stromkreises ist so bemessen, daß die Relais in der Ruhelage von einem Ruhestrom durchflossen werden, welcher ihre Anker e nicht zum Ansprechen bringt. Sobald in einen der geschützten Räume Wasser eindringt und die Platten b bedeckt, bilden diese einen besser leitenden Nebenschluß zu dem Widerstand a, so daß nun der Strom verstärkt durch das betreffende Relais fließen kann und dieses seinen Anker e anzieht, und z. B. eine Glühlampe f einschaltet. Das Aufleuchten der Lampe zeigt den gefährdeten Raum an.In the spaces to be protected, resistors α are accommodated, to which electrodes b are connected in parallel. The resistors β are connected on the one hand to one pole of the battery c and on the other hand to a relay d each. The total resistance of the circuit is dimensioned so that the relays are traversed by a quiescent current in the rest position, which does not cause their armature e to respond. As soon as water penetrates into one of the protected spaces and covers the plates b , they form a more conductive shunt to the resistor a, so that now the current can flow through the relevant relay and this attracts its armature e , and z. B. turns on an incandescent lamp f. The lighting of the lamp indicates the endangered room.
