Description
Die Erfindung betrifft eine Vorrichtung zum induktiven Messen der elektrischen Leitfähigkeit einer Flüssigkeit mit wenigstens zwei mit je einer Wicklung versehenen Ringkernen und einer die Flüssigkeit führenden, aus einem Zufluss, zwei durch die Ringkerne geführten Zweigen und einem Abfluss bestehenden Leiterschleife.The The invention relates to a device for inductive measuring of the electrical conductivity a liquid with at least two ring cores provided with one winding each and one the liquid leading, from a tributary, two branches led by the toroidal cores and a drain existing conductor loop.
Eine
derartige Anordnung ist aus der
Bei derartigen Vorrichtungen ist jeweils ein Zweig der die Flüssigkeit führenden Leiterschleife durch einen der Ringkerne geführt. Der eine der beiden Ringkerne trägt eine Erregerspule, der andere eine Empfangsspule. Der Widerstand der Flüssigkeit der die beiden Ringkerne miteinander koppelnden Leiterschleife ist ein Maß für die zu ermittelnde Leitfähigkeit der Flüssigkeit.at Such devices each have a branch of the liquid leading Conductor loop passed through one of the toroidal cores. The one of the two ring cores wears a Excitation coil, the other a receiving coil. The resistance of the Liquid the the two ring cores coupling conductor loop is a Measure for that too determining conductivity the liquid.
Ein Nachteil dieser Vorrichtungen besteht darin, dass diese von Gegenständen, die der Vorrichtung unmittelbar benachbart angeordnet sind, erheblich beeinflusst werden.One Disadvantage of these devices is that these objects, the the device are arranged immediately adjacent considerably to be influenced.
Aus
der
Der Erfindung liegt die Aufgabe zugrunde, die bekannte Vorrichtung dahingehend weiterzubilden, dass diese von außen weniger gestört werden kann.Of the Invention is based on the object, the known device to the effect to further educate that they can be disturbed less from the outside.
Erfindungsgemäß wird diese Aufgabe dadurch gelöst, dass die Leiterschleife in Form einer Acht ausgebildet ist und jeder der beiden einander kreuzenden Zweige der Leiterschleife durch beide Ringkerne geführt ist.According to the invention this Task solved by that the conductor loop is in the form of a figure eight and each one of the two crossing branches of the conductor loop through both ring cores guided is.
Durch diese Ausbildung der Leiterschleife, bei der jede der beiden einander kreuzenden Zweige der Leiterschleife sowohl durch den mit der Erregerspule versehenen Ringkern, als auch durch den mit der Empfangsspule versehenen Ringerkern geführt sind, werden störende Einflüsse kompensiert, die Vorrichtung ist gegenüber Störungen weniger anfällig.By this training of the conductor loop, where each of the two each other crossing branches of the conductor loop by both the excitation coil provided toroidal core, as well as by the provided with the receiving coil Ring core are guided, be disturbing influences compensates, the device is less susceptible to interference.
Die Erfindung wird im folgenden anhand einer Zeichnung erläutert. Dabei zeigt:The Invention will be explained below with reference to a drawing. there shows:
Die Anordnung besteht aus zwei je mit einer Wicklung versehenen Ringkernen und einer die Flüssigkeit führenden, aus einem Zufluss A, zwei durch die Ringkerne geführten Zweigen und einem Abfluss B bestehenden Leiterschleife. Die Leiterschleife ist in Form einer Acht ausgebildet, jeder der beiden einander kreuzenden Zweige der Leiterschleife sind durch beide Ringkerne geführt.The Arrangement consists of two each provided with a winding ring cores and one the liquid leading, from a tributary A, two branches led by the toroidal cores and a drain B existing conductor loop. The conductor loop is formed in the form of an eight, each of the two intersecting Branches of the conductor loop are guided through both ring cores.
