Abstract

An acoustic transducer for indicating a maximum permissible level of a conducting fluid in a container is esp. applicable but not limited to measuring bath tub water levels. It does not require mains power but an easily changed battery (22) whose voltage is too low to constitute a danger. The transducer (21) and battery (22) are mounted in a watertight housing (111). The measurement current circuit, is completed externally. For this purpose two electrodes (211,212) protrude through the housing base (1111) to contact the fluid when the appropriate level is reached. The housing has a bell-shaped cover (112) detachably mounted on the bath wall by magnets or suction pads (24). Between the housing and cover is a seal (23). The device is also applicable to explosive areas or wells.

Description

Akustischer Signalgeber zur Anzeige desAcoustic signal generator to display the

maximal zulässigen Füllstandes von leitfähigen Flüssigkeiten in Behältern Beschreibung Die Erfindung betrifft einen akustischen Signalgeber zur Anzeige des maximal zulässigen Fullstandes von leitfähigen Flüssigkeiten in Behältern.maximum permissible level of conductive liquids in containers description The invention relates to an acoustic signal generator for displaying the maximum permissible Full level of conductive liquids in containers.

Ein Bedarfsfall für ein solches Gerät ist die Anzeige des zulässigen bzw. gewünschten FUllstandes des Badewassers in Badewannen. Daraus ergibt sich eine Mindestanforderung an das Gerät. Es muß unabhängig vom Netz sein und die erforderliche Spannung muß so niedrig sein, daß eine Gefährdung von Personen ausgeschlossen ist.A need for such a device is the display of the permissible or desired fill level of the bath water in bathtubs. This results in a Minimum requirements for the device. It must be independent of the network and the required The voltage must be so low that there is no danger to people.

Erfindungsgemäß wird dem Rechnung tragend ein solches Gerät vorgeschlagen, das aus einem in einem flüssigkeitsdichten Gehäuse befindlichen, batteriegespeisten Signalgeber besteht, dessen unterbrochener Stromkreis in zwei aus dem Gehaiuseboden herausragenden Elektroden ausläuft.According to the invention, such a device is proposed to take account of this, from a battery-powered in a liquid-tight housing There is a signaling device whose interrupted circuit is divided into two from the bottom of the housing protruding electrodes leaks.

Im Falle der tiberwachung einer Badewannenfüllung wird das Gerät an der Wannenwandung in einer Höhe angeordnet, bei der sich die aus dem Boden des Gerätes herausragenden Elektroden etwa im Niveau des gewünschten Wasserstandes in der Wanne befinden. Sobald das Wasser dieses Niveau erreicht hat, wird der Stromkreis, in dem sich der Signalgeber und die ihn speisende Batterie liegt, kurzgeschlossen und der Signalgeber ertönt. Bei Entnahme des Gerätes aus der Wanne wird der Stromkreis ohne weiteres wieder unterbrochen. Im Bedarfsfall wird das Gerät sodann wieder installiert.In the case of monitoring a bathtub filling, the device is switched on the tub wall arranged at a height at which the out electrodes protruding from the bottom of the device at about the level of the desired water level are in the tub. Once the water reaches this level, the circuit will in which the signal transmitter and the battery supplying it are located, short-circuited and the signal generator sounds. When the device is removed from the tub, the circuit is interrupted again without further ado. If necessary, the device is then reinstalled.

Die Anwendung des Gerätes ist nicht auf Badewannen beschränkt Es kann gleichermaßen zur Signalisierung des zulässigen bzw.The application of the device is not limited to bathtubs. It can equally for signaling the permissible or

gewünschten FUllstandes in beliebig anderen Behältern dienen, die dann auch beliebig andere leitfähige Flüssigkeiten aufnehmen können. Das Gerät bietet sich insbesondere auch rür den Einsatz in explosionsgefährdeten Bereichen an. Ein weiterer Anwendungsfall ist die Püllstandsmessung in Brunnen oder dergleichen, wobei das Gerät an einer Meßschnur in den Schacht hinabgelassen wird.desired fill level in any other container that can then also absorb any other conductive liquids. The device offers particularly suitable for use in potentially explosive areas. A Another application is the level measurement in wells or the like, where the device is lowered into the shaft on a measuring cord.

Wesentlich ist, daß der Signalgeber und die ihn speisende Batterie in dem sie aufnehmenden Gehäuse flUssigkeitsgeschützt untergebracht sind. Gleichwohl soll die Batterie leicht auswechselbar sein.It is essential that the signal transmitter and the battery feeding it they are housed in a liquid-proof manner in the housing that accommodates them. Nevertheless the battery should be easily replaceable.

Dem wird in weiterer Ausgestaltung der Erfindung dadurch Rechnung getragen, daß das den Signalgeber und die Batterie aufnehmende, von oben zugängliche Gehäuse von einem glockenartigen, mit dem Gehäuse lösbar verbundenen Deckel Ubergriffen ist, der nach Art einer Taucherglocke das Innere des Gehäuses den Zutritt von Flüssigkeit abschirmt. Zwischen Gehäuse und Deckel kann zusätzlich eine Dichtung eingefügt sein. Zur vorübergehenden Installation des Gerätes können an der Deckelseitenwandung Haftmagnete oder Saugnäpfe vorgesehen sein, die es ermöglichen, das Gerät in der jeweils gewUnschten Höhe an der Behälterinnenwandung anzuordnen.This is taken into account in a further embodiment of the invention worn that the signal transmitter and the battery receiving, accessible from above The housing is overlapped by a bell-like cover that is detachably connected to the housing is that, like a diving bell, the interior of the housing allows liquid to enter shields. A seal can also be inserted between the housing and the cover. For temporary installation of the device, holding magnets can be attached to the side wall of the cover or suction cups can be provided, which make it possible to use the device in the desired manner To be arranged height on the inner wall of the container.

In der Zeichnung ist die Erfindung an Hand eines ganz schematisch dargestellten Ausführungsbeispieles weitergehend erläutert. Es zeigen: Figur 1 das Gerät in einem Vertikalschnitt, Figur 2 ein in einer Badewanne angeordnetes Gerät.In the drawing, the invention is very schematic on the basis of one illustrated embodiment explained in more detail. They show: Figure 1 that Device in a vertical section, Figure 2 a device arranged in a bathtub.

Kernstück des Gerätes 11 ist der von einer auswechselbaren Batterie 22 gespeiste akustische Signalgeber 21, dessen unterbrochener Stromkreis in zwei im Abstand voneinander angeordnete Elektroden 211, 212 ausläuft.The heart of the device 11 is that of a replaceable battery 22 fed acoustic signal generator 21, the interrupted circuit in two electrodes 211, 212 arranged at a distance from one another runs out.

Signalgeber 21 und Batterie 22 sind in einem von oben zugänglichen Gehäuse 111 angeordnet, durch dessen Boden 1111 sich die Elektroden 211, 212 des Signalgebers 21 flüssigkeitsdicht abgedichtet nach außen erstrecken. Das Gehäuse 111 ist von einem sich bis in den Bereich des Gehäusebodens 1111 erstreckenden Deckel 112 übergriffen, wobei zwischen Gehäuse 111 und Deckel 112 eine Dichtung 23 eingefügt sein kann. An der Deckelseitenwandung 1121 sind Saugnäpfe 24 angeordnet.Signal transmitter 21 and battery 22 are in one accessible from above Housing 111 arranged, through the bottom 1111 of the electrodes 211, 212 of the Signal transmitter 21 extend liquid-tight sealed to the outside. The case 111 is from a cover that extends into the area of the housing bottom 1111 112 overlapped, a seal 23 being inserted between housing 111 and cover 112 can be. Suction cups 24 are arranged on the cover side wall 1121.

Im Bedarfsfall wird das Gerät 11 etwa an der Badewannenwandung 311 angesetzt, und zwar in einer solchen Höhe, daß die aus dem Gehäuseboden 1111 herausragenden Elektroden 211, 212 geringfügig unterhalb der gewünschten FUllhöhe H der Wanne 31 mit Badewasser 41 enden. Erreicht das in die Wanne 31 eingelassene Wasser 41 die Elektroden 211, 212, wird der Stromkreis, in dem der Signalgeber 21 liegt, kurzgeschlossen, und ein akustisches Signal ertönt, das den erreichten Füllstand anzeigt.If necessary, the device 11 is attached to the bathtub wall 311, for example attached, and at such a height that the protruding from the housing bottom 1111 Electrodes 211, 212 slightly below the desired filling height H of the trough 31 end with bath water 41. If the water 41 let into the tub 31 reaches the Electrodes 211, 212, if the circuit in which the signal generator 21 is located is short-circuited, and an acoustic signal sounds indicating the level reached.
