Description

Meßwertaufnehmβr für magnetisch-induktive Durchfluß- meßgeräteSensor for magnetic-inductive flowmeters
Die Erfindung betrifft einen Meßwertaufnehmer für magnetisch-induktive Durchflußmeßgeräte, bestehend aus einem in einem Stahlgehäuse angeordneten und mit Meßelektroden .ausgerüsteten Meßrohr, auf dem diametral gegenüberliegend zwei Matnetspulen angeordnet sind, die jeweils mit einem bolzenartigen Spulenkern versehen sind, der mit einem flanschartig erweiterten Fuß gegen das Meßrohr anliegt, mit seinem Kopfende am Stahlge¬ häuse befestigt ist und eine Wickelspule aus einem dielektrischen Werkstoff besitzt.The invention relates to a transducer for electromagnetic flowmeters, consisting of a measuring tube arranged in a steel housing and equipped with measuring electrodes. On the diametrically opposite two magnet coils are arranged, each of which is provided with a bolt-like coil core, which has a flange-like widened foot against the measuring tube rests, is attached with its head end to the steel housing and has a winding spool made of a dielectric material.
Bei einem bekannten Meßwertaufnehmer dieser Art ist die zuvor mit dem Spulendraht bewickelte Wickelspule auf den bolzenartigen Spulenkern aufgesteckt. Zur Be- festigung der Magnetspule im Stahlgehäuse und der Siche¬ rung der Wickelspule gegen axiale Verschiebung ist unter Zwischenlage einer Füllscheibe ein Deckelteil auf das Kopfende des Spulenkerns aufgesteckt, der mittels eines in eine Ringnut des Stahlgehäuses eingreifenden Spreng- rings fixiert ist; diese Befestigung mit Hilfe mehrerer Bauteile ist umständlich, teuer und für eine Band- Roboter-Montage ungeeignet.In a known transducer of this type, the winding coil previously wound with the coil wire is attached to the bolt-like coil core. To fasten the magnetic coil in the steel housing and to secure the winding coil against axial displacement, a cover part is placed on the head end of the coil core with the interposition of a filler disc, which is fixed by means of a snap ring engaging in an annular groove of the steel housing; this attachment with the help of several components is cumbersome, expensive and for a tape Robot assembly unsuitable.
Der Erfindung liegt die Aufgabe zugrunde, einen Me߬ wertaufnehmer der gattungsgemäßen Art derart auszu- bilden, daß bei einem einfachen Aufbau eine besonders einfache Montage ermöglicht wird, die bedarfsweise auch für den Einsatz von Robotern geeignet ist.The invention is based on the object of designing a sensor of the generic type in such a way that, with a simple structure, particularly simple assembly is made possible, which, if necessary, is also suitable for use with robots.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß am Kopfende des Spulenkerns ein Flansch ange¬ bracht ist und die Wickelspule aus zwei halbschalen- förmigen, um den Spulenkern liegenden Spulenteilen besteht, auf denen der Spulendraht aufgewickelt ist.This object is achieved in that a flange is attached to the head end of the coil core and the winding coil consists of two half-shell-shaped coil parts lying around the coil core, on which the coil wire is wound.
Mit Hilfe des Flansches, der beispielsweise beim Gießen des Spulenkerns angeformt wurde, lassen sich die vorge¬ fertigten Magnetspulen am Stahlgehäuse durch Schweißen o. dgl. befestigen. Da durch diese Ausbildung des Spu¬ lenkerns die Wickelspule nicht mehr auf den- Spulenkern axial aufsteckbar ist, ist eine Längsteilung der Wickel¬ spule vorgesehen, die eine radiale Anlage der beiden halbschalenförmigen Spulenteile erlaubt. Der Spulen¬ draht wird auf die zuvor um den Spulenkern gelegte Wic elspule gewickelt. Durch die Flanschverbindung und deren unmittelbare Anlage gegen das Stahlgehäuse entsteht ein besonders guter Rückschluß zwischen den beiden Magnetspulen.With the help of the flange, which was formed, for example, when casting the coil core, the prefabricated magnet coils can be attached to the steel housing by welding or the like. Since the winding spool can no longer be axially plugged onto the spool core as a result of this design of the spool core, a longitudinal division of the winding spool is provided which allows the two half-shell-shaped spool parts to rest radially. The coil wire is wound on the winding coil previously placed around the coil core. The flange connection and its direct contact with the steel housing create a particularly good conclusion between the two solenoids.
Vorzugsweise besteht der Flansch des Spulenkerns aus zwei angeformten, diametral gegenüberliegenden Armen, deren äußeres Ende mit einem gegen das Stahlgehäuse anliegenden Schenkel versehen ist. Die Schenkel ge¬ statten eine gute Anlage am Gehäuse und eine gute Ver¬ schweißung. Um die beiden Spulenteile der Wickelspule in ihrer Anlageposition zu verbinden, können diePreferably, the flange of the coil core consists of two integrally formed, diametrically opposite arms, the outer end of which is provided with a leg abutting against the steel housing. The legs allow good contact with the housing and good welding. To connect the two coil parts of the winding coil in their contact position, the
Spulenteile mit teilweise überlappenden Endflanschen versehen sein, die sich durch Schnappriegel o. d.gl. verriegeln. Eine hohe Packungsdichte der Spulen läßt sich dadurch erzielen, daß der Mantel der Wickelspule mit Führungsrillen für denSpulendraht versehen ist. Außerdem wird durch die exakte Führung des Spulen¬ drahtes die Gerätekonstante verbessert. Zweckmäßig sind an einen Endflansch der vorzugsweise aus Kunst¬ stoff gespritzten Wickelspule zwei Drahtklemmen für die Enden des Spulendrahtes angeformt, so daß eine genaue Fixierung der Drahtenden erzielbar ist.Coil parts with partially overlapping end flanges be provided, or the like by snap bolts. lock. A high packing density of the coils can be achieved in that the jacket of the winding coil is provided with guide grooves for the coil wire. In addition, the device constant is improved by the exact guidance of the coil wire. Two wire clamps for the ends of the coil wire are expediently molded onto an end flange of the winding spool, which is preferably injection-molded from plastic, so that the wire ends can be precisely fixed.
