Description

Elektrische Treibstoff-Standanzeiger für Fahrzeuge, bei denen ein Schwimmer einen ohmschen Widerstand verstellt, dessen jeweiliger Wert oder eine ihm proportionale Größe durch ein Meßgerät am Armaturenbrett des Fahrzeuges angezeigt wird, sind bekannt. Ferner ist die zusätzliche Einrichtung -einer Warnlampe bekannt, die aufleuchtet, wenn der Stand des Betrieb&stoffes im Vorratsbehälter ein Minimum erreicht hat, um die Notwendigkeit einer Wiederauffüllung anzuzeigen. Bei derartigen Einrichtungen sind zwischen dem Geberwiderstand und dem Meßgerät bzw. zwischen dem am Geber befindlichen Schaltkontakt für die Warnlampe und der Warnlampe im Meßgerät je eine Verbindungsleitung, im ganzen also zwei Leitungen notwendig. Electric fuel level indicators for vehicles that have a Float adjusts an ohmic resistance, its respective value or a proportional size indicated by a measuring device on the dashboard of the vehicle is known. Furthermore, the additional device -a warning lamp is known, which lights up when the level of the material in the storage container is at a minimum has reached to indicate the need for replenishment. With such Facilities are between the transmitter resistor and the measuring device or between the Switching contact located on the encoder for the warning lamp and the warning lamp in the measuring device One connecting line each, so a total of two lines are required.

Die Erfindung betrifft eine Einrichtung der genannten Art, die derart geschaltet ist, daß nur eine einzige Verbindungsleitung zwischen dem Geber und dem Meßgerät mit Warnlampe erforderlich ist. The invention relates to a device of the type mentioned, the such is connected that only a single connection line between the encoder and the Measuring device with warning lamp is required.

Zu diesem Zweck ist die Warnlampe im Meßgerät mit diesem in Reihe geschaltet und der Warnkontakt im Geber derart angebracht, daß der Schleifer des Geberwiderstandes bei Berührung des Warnkontaktes den restlichen Geberwiderstand kurzschließt und damit den Meßstrom derart erhöht, daß die Warnlampe aufleuchtet. Dabei ist der Kaliwiderstand der Glühlampe klein gegen die Größe des Restgeberwiderstandes, so daß das Auswechseln der Glühlampe keine unzulässige Änderung der Anzeige am Meßgerät hervorruft. In der Zeichnung ist eine Skizze der Schaltung dargestellt.For this purpose, the warning lamp in the measuring device is in series with it switched and the warning contact mounted in the encoder in such a way that the wiper of the Encoder resistance when touching the warning contact the remaining encoder resistance short-circuits and thus increases the measuring current so that the warning lamp lights up. The potassium resistance of the incandescent lamp is small compared to the size of the residual sensor resistance, so that changing the light bulb does not inadmissibly change the display on the measuring device evokes. A sketch of the circuit is shown in the drawing.

Auf dem Geberwiderstand I von etwa IOO Ohm bewegt sich der geerdete bzw. an den Minuspol der Fahrzeugbatterie angeschlossene Schleifkontakt 2, der durch einen nicht gezeichneten Schwimmer bekannter Art verstellt wird. Bei einer Stellung des Schleifkontaktes, der beispielsweise einem Restinhalt des Vorratsbehälters von 3 bis 4 1 entspricht, befindet sich ein Kontakt 3, bei dessen Berührung durch den Schleifkontakt 2 der restliche Widerstand von etwa 40 Ohm kurzgeschlossen wird. Vom Geber zum Meßgerät führt eine einzige Leitung 4, und zwar zunächst zu der in das Meßgerät 5 eingebauten Warnlampe 6 und dann zu den Spulen des Meßgeräts, das seinerseits an den Pluspol der Fahrzeugbatterie angeschlossen ist.The earthed one moves on the encoder resistance I of about 100 ohms or sliding contact 2 connected to the negative pole of the vehicle battery, through a not shown float of a known type is adjusted. At one position of the sliding contact, for example, a remaining content of the storage container of 3 to 4 corresponds to 1, there is a contact 3, when touched by the Sliding contact 2 the remaining resistance of about 40 ohms is short-circuited. A single line 4 leads from the encoder to the measuring device, initially to the in the measuring device 5 built-in warning lamp 6 and then to the coils of the measuring device that in turn is connected to the positive terminal of the vehicle battery.
