Description
Goniometeranorenung Bei Goniometern treten bekanntlich verschiedene innere Fellller auf, die auf den mechanischen Aufbau bzw. magnetische Rückwirkungen der Felder oder andere Einflüsse zurückzuführen sind. Die hauptsächlichen inneren Fehler sind sog. Achtelkreisigkeit, Viertelkreisigkeit und Halbkrei sigk eit. Zur Beseitigung der Achtelkreisigkeit und Viertelkreisigkeit sind verschiedene Methoden angegeben worden, jedoch ist es bisher nicht möglich gewesen, die Halbkreisigkeit wirkungsvoll zu beseitigen bzw. den hierdurch auftretenden Fehler in kleinen Grenzen zu halten.Goniometer anorenung It is well known that different goniometers occur inner Fellller on, which on the mechanical structure or magnetic repercussions the fields or other influences. The main internal ones Errors are so-called eighth-circle, quarter-circle and semicircularity. To the Eighth circle and quarter circle elimination are different methods has been specified, however, it has not yet been possible to use the semicircular shape to effectively eliminate or the errors occurring as a result within small limits to keep.
Gemäß der Erfindung wird die Komplensation der Halbkrelsigkeit dadurch vorgekommen, daß in Reihe mit der beweglichen Suchspule eine von der Bewegung der Suchspule in ihrer Lage nicht abhängige, vorzugsweise auswechselbare und umpolbare Hilfsspule liegt, die mit leiner der feststehenden Feldspulen magnetisch gekoppelt ist. According to the invention, the compensation of the half-circle is thereby it has happened that in series with the movable search coil one of the movement of the Search coil, which is not dependent on its position, is preferably exchangeable and polarity reversible Auxiliary coil, which is magnetically coupled to one of the fixed field coils is.
An Hand der beispielsweisen Abbildung ist der Erfindungsgedanke im folgenden erläutert. In der Abb. I bedeuten I bis IV die Feldspulen des Goniometers und S die Suchspule, deren Zuleitungen verdrillt sind. K bedeutet die zusätzliche Koppelspule, deren Zuleitungen gegebenenfalls ebenfalls verdrillt sind und die mit der Suchspule in Reihe liegt. Der Windungssinn und die Windungszahl dieser Koppeispule sind von Fall zu Fall versdhieden und hängen von den Ursachen der zu kompensierenden Halbkreisigkeit ab. On the basis of the exemplary illustration, the inventive idea is in explained below. In Fig. I, I to IV mean the field coils of the goniometer and S the search coil, the leads of which are twisted. K means the additional Coupling coil, the leads of which are possibly also twisted and with the search coil is in series. The sense of turns and the number of turns of this coupling coil differ from case to case and depend on the causes of the compensation Semicircular shape.
Der Kopplungsgrad der Hilfsspule mit der Feldspule ist veränderlich gehalten.The degree of coupling of the auxiliary coil with the field coil is variable held.
Die Kopplungsspule K braucht nicht direkt mit einer der Feldspulen gekoppelt zu sein, sondern es genügt oft, sie im Streufeld der Feldspulen anzuordnen. In der Abb. I sind verschiedene Fälle für derartige Spulenanordnungen gezeigt und mit I bis 4 bezeichnet. The coupling coil K does not need to be connected directly to one of the field coils to be coupled, but it is often sufficient to arrange them in the stray field of the field coils. Various cases for such coil arrangements are shown in FIG labeled I to 4.
Abb. 2 zeigt verschiedene Fälle der auftretenden Halbkreisigkeit für die in Abb. I angegebenen Kopplungsmglichkeiten I bis 4.Fig. 2 shows different cases of semicircularity for the coupling options I to 4 shown in Fig. I.
In den gezeigten Kurven ist jedesmal der Fehler in Grad über dein Peilwinkel von o bis 3600 aufgetragen. Es zeigt sich, daß sich die Halbkreisigkeit entsprechend der veränderten Kopplung I bis 4 in der Richtung der Abszisse verschiebt. Eine Umpolung der Koppelspule K würde die Halbkreisigkeit um 1800 um die Abszisse als Achse herumklappen. Durch die Anordnung einer zusätzlichen Koppelspule und durch die Erkenntnis der Verschiebung der Halbkreisigkeit durch Art und Grad der Kopplung ist es möglich, jede auftretende Art der Halbkreisigkeit zu kompensieren bzw. den durch sie auftretenden Fehler in erträglichen Grenzen zu halten.In each of the curves shown, the error in degrees is above yours Bearing angles from 0 to 3600 are applied. It turns out that the semicircular shape shifts according to the changed coupling I to 4 in the direction of the abscissa. Reversing the polarity of the coupling coil K would make the semicircular shape around 1800 around the abscissa fold around as an axis. By arranging an additional coupling coil and by the knowledge of the displacement of the semicircular shape through the type and degree of coupling it is possible to compensate for every occurring type of semicircular shape or the to keep errors that occur as a result of them within tolerable limits.
