    Wirbelstrom-Gesehivindigkeitsniesser.   
 EMI1.1 
 keitsmessers besteht darin, dass der Rückschlusskörper eine über der Anzeigescheibe befindliche Ringscheibe mit einem den radialen Polausschnitt des Ringmagneten   entsprechenden     Ausschnitt bildet,   der durch Drehung der Ringscheibe so eingestellt werden kann. dass er sieh mit dem Polausschnitt deckt oder diesem gegenüber verschoben ist. 



   Gemäss der Erfindung ist diese Rüekschlussseheibe durch einen Hülsenförmigen gewindetragenden Ansatz zu einer schraubbaren Kappe ausgebildet, die sieh um den zur Abdeckung des Polausschnittes erforderliehen Winkel und zugleich axial   zum Ringmagneten verstellen lässt. wodurch   die Dichte des 
 EMI1.2 
 weitesten Grenzen geändert werden kann. 



   Ferner ist bei dieser Ausbildung des   Rücksehlusskörpers   der Vorteil gegeben. Dass derselbe kurz geschlossen ist. 



   Ausserdem wird durch die gleichmässige Massenverteilung des Rückschlusskörpers eine Zentrifugalwirkung, die ein Verstellen oder Loslösen desselben zur Folge haben könnte, nicht ausgelöst. 



   Schliesslich werden bei dieser Anordnung Befestigungsschrauben vermieden und die hiedureh   gegebene Möglichkeit ausgeschlossen,   dass sieh der Rüeksehlusskörper beim Lockern der Befestigungsschrauben verstellen konnte. 



   In der Zeichnung ist ein der Erfindung gemäss ausgebildeter Wirbelstrom-Geschwindigkeitsmesser beispielsweise veranschaulicht, u.   zw.   zeigt :
Fig. 1 denselben im Schnitt, teilweise in Ansicht, und 
 EMI1.3 
 gleichen   Aussengewinde   versehenen Trommel 4 aufgeschraubt, die in bekannter Weise fest an der Antriebswelle 3 sitzt und den Ringmagneten 5   aufnimmt.

    Eddy current social nourishment.
 EMI1.1
 keitsmesser consists in that the return body forms an annular disc located above the indicator disc with a cutout corresponding to the radial pole section of the ring magnet, which can be adjusted by rotating the annular disc. that it coincides with the pole section or is shifted in relation to it.



   According to the invention, this return disk is formed by a sleeve-shaped thread-bearing extension to form a screwable cap which can be adjusted by the angle required to cover the pole section and at the same time axially to the ring magnet. whereby the density of the
 EMI1.2
 broadest limits can be changed.



   Furthermore, the advantage is given in this design of the return body. That it is short-circuited.



   In addition, due to the uniform mass distribution of the return body, a centrifugal effect, which could result in an adjustment or loosening of the same, is not triggered.



   Finally, with this arrangement, fastening screws are avoided and the possibility given here that the back body could be adjusted when the fastening screws are loosened is excluded.



   In the drawing, an eddy current speedometer designed according to the invention is illustrated, for example, u. between shows:
Fig. 1 the same in section, partially in view, and
 EMI1.3
 The same external thread provided drum 4 is screwed, which sits firmly in a known manner on the drive shaft 3 and receives the ring magnet 5.
