Description
Bei kontaktloser Drehzahlentnahme vermittels eines Oszillators mit veränderlicher Stromentnahme ist es manchmal wünschenswert, daß das Ein- oder Aussetzen des Oszillators von einer verhältnismäßig kleinen Blende gesteuert wird. Ein typisches Beispiel 5 dafür ist die Benutzung des oben zitierten Oszillators als Impulsquelle für die Fernübertragung von elektrischen Größen, ein sogenanntes Fernmessen in der Energetik. Bisher wurden für diesen Zweck Fotozellen verwendet, welche abwechselnd von einer Glühlampe belichtet wurden, deren Licht durch einen schmalen, vermittels einer sich drehenden, mit Ausschnitten versehenen Scheibe abwechselnd geblendeten Spalt hindurchging. Diese Ausschnitte sind in gegebenem Falle etwa 3 mm breit.With contactless speed extraction by means of an oscillator with variable current consumption it is sometimes desirable that the on or off of the oscillator be relatively small aperture is controlled. A typical example of this is the use of the oscillator cited above as a pulse source for the remote transmission of electrical quantities, a so-called remote measurement in the Energetics. So far, photocells have been used for this purpose, which alternate with an incandescent lamp whose light was exposed through a narrow, by means of a rotating, with cutouts Disc alternately blinded gap went through. These excerpts are in the given case about 3 mm wide.
Für diesen Zweck wurde gemäß der Erfindung im Oszillationskreis eine Einrichtung laut Zeichnung vorgesehen. Ein aus einem Werkstoff hoher Permeabilität hergestelltes Joch 1 ist mit zwei Spulen versehen, die eine Rückkopplungs- und Oszillationswicklung bilden. Dem Joch sind zwei Polansätze 2 angelegt, welche auf einer oder zwei Schirmplatten 4 aus leitendem Werkstoff, z. B. Aluminium, eng anliegen. Zwischen diesen Schirmplatten ist ein Spielraum, in welchem sich die Steuerblende 7 bewegt. Die Schirmplatten sind mit geschlossenen öffnungen 6 versehen, durch welche das Joch hindurchgeht. Diese öffnungen sind durch je einen schmalen Ausschnitt verlängert, welchem die Polansätze anliegen. Beide Spulen 3 können bloß vermittels der öffnung in der Schirmplatte über das Joch und die Polansätze gekoppelt werden, denn die Schirmplatte bildet für das übrigbleibende Streufeld eine Kurzschlußwicklung. Im Falle, daß ein Teil des Ausschnittes 6 unter den Polansätzen geblendet wird, verringert sich der Kopplungsgrad zwischen den beiden Spulen.For this purpose, according to the invention, a device according to the drawing was provided in the oscillation circuit. A yoke 1 made of a material of high permeability is provided with two coils, which form a feedback and oscillation winding. Two pole attachments 2 are attached to the yoke, which on one or two shield plates 4 made of conductive Material, e.g. B. aluminum, fit tightly. Between these faceplates there is a margin in which the control panel 7 moves. The shield plates are provided with closed openings 6, through which the yoke passes. These openings are each extended by a narrow cutout, which the pole approaches lie. Both coils 3 can merely by means of the opening in the faceplate be coupled via the yoke and the pole approaches, because the shield plate forms for the remaining Stray field a short-circuit winding. In the event that part of the cutout 6 is blinded under the pole approaches the degree of coupling between the two coils is reduced.
Durch die Anordnung gemäß der Zeichnung wurde eine verläßliche Funktion des Oszillators beim Steuern vermittels Scheibe mit einem 3 mm Spielraum und Blenden erzielt. Die Funktion ist ähnlich wie beim Fotozellenentnehmer, jedoch die Benutzung von Glühlampen und Fotozellen entfallen, d. h. also jene Bestandteile, welche der Abnutzung unterliegen. Die Lebensdauer bei Benutzung eines Transistors ist theoretisch unbegrenzt. Hierbei wird eine weit bessere energetische Bilanz der ganzen Einrichtung erzielt.The arrangement according to the drawing enabled the oscillator to function reliably during control achieved by means of a disc with a 3 mm clearance and diaphragms. The function is similar to that of the Photocell removers, but the use of light bulbs and photocells is not required, d. H. so those components which are subject to wear and tear. The service life when using a transistor is theoretically unlimited. This results in a far better energy balance for the entire facility.
