Description

Vorrichtung zum Anzeigen von Flüssigkeitsständen Es wurde gefunden, daß man bei Vorrichtungen zum Anzeigen von Flüssigkeitsständen in Flussigkeitsstandrohren aus nichtmagnetischem Werkstoff mit Hilfe eines magnetischen Schwimmers, der außerhalb des Standrohres betindliche Stromkreise beeinflußt, eine besonders genaue Anzeige erhält, wenn man die Anzeigestromkreise als Sxchwingungskreise mit einer Glimmlampe uls .Anzeigeglied ausbildet. Zu diesem Zwecke schaltet man eine oder mehrere einfache Spulen L s. Nhh. 1 mit je einer Glimmlampe G parallel und schließt sie über je einen Kondensator C an eine Welchselstromquelle N an. Die einzelnen Teile müssen dabei so gegeneinander ahgestimmt sein, daß erst beim Einführen des Einsenkernes E in die betreffende Spule die Zündspannung der zugehörigen Glimmlampe erreicht wird und diese Glimmlampe zum Aufleuchten kommt.Device for displaying liquid levels It was found that one with devices for displaying liquid levels in liquid standpipes made of non-magnetic material with the help of a magnetic float, the outside of the standpipe influences relevant circuits, a particularly accurate display obtained if the display circuits are used as oscillating circuits with a glow lamp uls. Indicator element trains. For this purpose one switches one or more simple ones Bobbins L see Nhh. 1 each with a glow lamp G in parallel and closes them via one each Capacitor C to a alternating current source N. The individual parts must be there be so mutually attuned that only when inserting the indented core E in the coil in question has reached the ignition voltage of the associated glow lamp and this glow lamp lights up.

Abb. 2a. 2b und 3 zeigen die Zusammenfassung der Spulen L, Glimmlampen G und Kondensatoren G zu Einheiten, von denen beliebig viele s. Abb. 3' an einem Flüssigkeisstandrohr angebracllt werden können. Fig. 2a. 2b and 3 show the combination of the coils L, glow lamps G and capacitors G to form units, of which any number (see Fig. 3 ') on one Liquid standpipe can be attached.

Als Eisenkern dient z.B. ein mit Eisen bewehrter oder aus dünnem Eisenblech geformter Schwimmer, der von der zu Messenden Flüssigkeit getragen wird.An iron core or thin sheet iron, for example, serves as the iron core shaped float that is carried by the liquid to be measured.

Zur Abgleichung der verschiedenen Zundspannungen, die die Anzeigeglimmlampen infolge ungenauer herstellung oft haben, kann man in die gemeinsame Rückleitung noch eine weitere Glimmlampe Gs, die zweckmäßig verdeckt ist. einschalten (Abb. 41, Neben den Glimmlampen können noch elektrische Spannungsmesser zur Anzeige der Spanungsunterschiede verwendet und Relais zu Steuerung von Signalen, Pumpen oder Ventien ausgeschlossen vwerden. To balance the different ignition voltages that the indicator glow lamps as a result of inaccurate production, you can often have it in the common return line yet another glow lamp Gs, which is expediently covered. switch on (Fig. 41, In addition to the glow lamps, electrical voltmeters can also be used to display the Used voltage differences and relays to control signals, pumps or Ventien be excluded.
