FüllstandsgeberLevel sensor

Die Erfindung betrifft einen Füllstandsgeber gemäß dem Oberbegriff des Anspruchs 1.The invention relates to a level sensor according to the preamble of claim 1.

Derartige Füllstand ^geber sind an einem Deckel angebracht, der gleichzeitig bei der Montage den Tank nach oben abdichtend verschließt. Such level sensors are attached to a cover, the at the same time during assembly the tank closes sealingly at the top.

Nachteilig bei diesem Stand der Technik ist, daß die örtliche Lage des Geberelementes bezüglich des Schwimmers durch den Deckel des Tankes fixiert wird. Im Falle von Wärmungsausdehnung kommt es zu einem Ausbeulen des Tankbodens, wodurch relativ zum Deckel der Flüssigkeitsspiegel absinkt, obwohl der Flüssigkeitsinhalt unverändert geblieben ist. Aufgrund des größeren Abstandes des Spiegels zum Deckel sinkt der Schwimmer relativ zum Deckel, wodurch eine Fehlinformation bei der Tankinhaltsanzeige erhalten wird.The disadvantage of this prior art is that the local position of the transmitter element with respect to the float by the Lid of the tank is fixed. In the case of thermal expansion the bottom of the tank bulges, which causes the liquid level to drop relative to the lid, although the Fluid content has remained unchanged. Because of the larger At a distance between the mirror and the lid, the float sinks relative to the lid, which causes incorrect information on the tank content display is obtained.

Aufgabe der Erfindung ist es, die Genauigkeit der Anzeige zu verbessern.The object of the invention is to improve the accuracy of the display.

Die Aufgabe wird gelöst durch den Anspruch 1. Erfindungsgemäß ist vorgesehen, den Geber nicht starr mit dem Oeckel zu verbinden, sondern das Geberelement, das gleichzeitig der Anlenkungspunkt für den Schwimmer ist, starr mit dem Tankboden zu verbinden. Damit wird erreicht, daß bei einem Auswölben des Bodens nach unten der Anlenkungspunkt für dew Schwimmer sich nach unten verschiebt und somit das Absinken des Flüssigkeitsspiegels durch dieses Absenken des Schwimmeraufhängungspunktes kompensiert wird.The object is achieved by claim 1. According to the invention It is provided that the encoder is not rigidly connected to the Oeckel, but rather the encoder element, which is also the point of articulation for the float is to be rigidly connected to the bottom of the tank. This ensures that when the bottom bulges downwards the pivot point for the swimmer moves downwards and thus the lowering of the liquid level is compensated by this lowering of the float suspension point.

Eine bevorzugte Ausführungsform der Erfindung ist im Anspruch 2 beschrieben.A preferred embodiment of the invention is in the claim 2 described.

Im folgenden wird die Erfindung detailliert dargestellt anhand der einzigen Figur.The invention is illustrated in detail below with reference to the only figure.

Mit dem Bezugszeichen 10 ist schematisch ein Tank dargestellt, der einen Einfüllstutzen 12 besitzt. In dem Tank befindet sich Flüssigkeit mit einem Flüssigkeitsspiegel 14.A tank which has a filler neck 12 is shown schematically with the reference numeral 10. In the tank is Liquid with a liquid level 14.

Mit 16 ist ein im unteren Bereich des Tankes befindlicher Schwalltopf, beispielsweise mit einem Sieb versehen, dargestellt, der gleichzeitig eine Halterung 18 trägt, die als aufrechtstehender Stab ausgebildet ist. Am Ende der Halterung 18 befindet sich ein Geberelement 20, das ein Gestänge 22 trägt. Das Gestänge 22 ist um einen Drehpunkt 24 drehbar, das eine Ende des Gestänges 22 trägt einen Schwimmer 30, der auf dem Flüssigkeitsspiegel 14 aufschwimmt, das andere Ende des Gestänges 22 ist mit einem Schleifer 26 versehen, der über eine Potentiometerbahn 28 schleift. Über die Potentiometerbahn 28 läßt sich ein Widerstandswert abgreifen, der von der Stellung des Armes 26 und somit von der Stellung des Gestänges 22 abhängig ist, letztlich also von der Höhe des Schwimmers 30, die unmittelbar an die Höhe des Flüssigkeitsspiegels 14 gekoppelt ist. Über ein Kabel 32 läßt sich die Information über den Wert des Widerstandes der Widerstandsbahn 28 an einen Anschluß 34 herausführen, von wo aus eine weiter Verarbeitung des Informaticr.swertes möglich ist.At 16 is a surge pot located in the lower area of the tank, For example, provided with a sieve, shown, which also carries a holder 18, which as an upright Rod is formed. At the end of the bracket 18 is located a transmitter element 20, which carries a linkage 22. The linkage 22 is rotatable about a pivot point 24 which is one end of the Linkage 22 carries a float 30 which floats on the liquid level 14, the other end of linkage 22 is provided with a grinder 26 which grinds over a potentiometer track 28. Via the potentiometer track 28 can be a Pick up resistance value, which is dependent on the position of the arm 26 and thus on the position of the linkage 22, ultimately that is, from the height of the float 30, which is directly coupled to the height of the liquid level 14. About a Cable 32 can lead out the information about the value of the resistance of the resistance track 28 to a connection 34, from where further processing of the information value is possible is.

Erfindungsgemäß ist nun vorgesehen, daß die Haltp^ung 18 am Boden des Tankes 10 oder an dem mit dem Boden des Tankes 10 verbundenen Schwalltopf 16 befestigt ist. Dehnt sich nun das Volumen des Tankes 10 beispielsweise durch Wärmeeinwirkung aus, führt dies zu einem Ausbauchen des Bodens, wodurch der Boden absinkt und sich der Flüssigkeitsspiegel 14 im Tank senkt. DiesAccording to the invention it is now provided that the Haltp ^ ung 18 on Bottom of the tank 10 or on the one with the bottom of the tank 10 connected surge pot 16 is attached. If the volume of the tank 10 expands, for example due to the action of heat, this leads to a bulging of the bottom, as a result of which the bottom sinks and the liquid level 14 in the tank lowers. this

umso mehr, als der Ausdehnungskoeffizient des sich über dem Flüssigkeitsspiegel 14 befindlichen Gases sehr viel größer ist als der Ausdehnungskoeffizient der Flüssigkeit.all the more so as the expansion coefficient of the Liquid level 14 located gas is very much greater than the expansion coefficient of the liquid.

Bei bisher üblichen Tanks, bei denen das dem Bauteil 20 entsprechende Geberelement am Deckel befestigt ist, entfernt sich somit der Flüssigkeitsspiegel 14 von dem Geberelement trotz gleichbleibender Flüssigkeitsmenge durch die Ausbauchung des Bodens, so daß eine Fehlanzeige erhalten wird.In the case of tanks that have been customary up to now, in which the component 20 corresponding Transmitter element is attached to the cover, the liquid level 14 thus moves away from the transmitter element despite the fact that it remains the same Amount of liquid through the bulge of the bottom, so that a false indication is obtained.

Erfindungsgemäß jedoch ist das Geberelement 20 starr mit dem Boden des Tankes 10 verbunden, so daß ein Ausbauchen des Bodens nach unten zu einer gleichzeitigen Absenkung des Geberelementes 20 führt, so daß die relative Stellung des Gestelles 22 zum Geberelement 20 im wesentlichen unverändert bleibt und somit der Fehler, der durch Temperaturänderungen auftreten könnte, kompensiert wird.According to the invention, however, the transmitter element 20 is rigidly connected to the bottom of the tank 10, so that a bulging of the bottom leads to a simultaneous lowering of the transmitter element 20, so that the relative position of the frame 22 to the transmitter element 20 remains essentially unchanged and thus the error that could occur due to temperature changes, is compensated.
