Geführter Glasschwimmer mit Metallband zum Schalten und Regeln durch Lichtschranken und magnetische Wegaufnehmer Guided glass float with metal band for switching and regulating through light barriers and magnetic displacement sensors
Im technischen Glasapparatebau werden häufig Lichtschranken zur Niveauhaltung durch Zweipunktregelung eingesetzt. Ein durch die Flüssigkeit getragener abgedunkelter Schwimmer unterbricht dabei den Lichtstrahl vom Sender zum Empfänger oder gibt ihn frei.In technical glass apparatus construction, light barriers are often used to maintain levels through two-point control. A A darkened float carried by the liquid interrupts the light beam from the transmitter to the receiver or releases him.
Das Arbeitsprinzip des magnetischen Wegaufnehmers ist analog; der Schwimmer muß lediglich eine ferromagnetische Metalleinlage enthalten.The working principle of the magnetic displacement transducer is analogous; the swimmer only needs a ferromagnetic metal insert contain.
Bei diesen bekannten Regelvorrichtungen kommt es häufig vor, daß der Schwimmer infolge seiner ungenauen Lage den Lichtstrahl zwischen Sender und Empfänger nicht völlig unterbricht, sondern beispielsweise durch Reflektion einen Teil des Lichtes auf den Smpfänger fallen läßt.In these known regulating devices, it often happens that the float, due to its imprecise position, the light beam between the transmitter and receiver is not completely interrupted, but rather some of the light is reflected on the, for example Drops receiver.
Bei der Arbeitsweise des magnetischen Wegaufnehmers kann es vorkommen, daß der freischwebende Schwimmer sich zu weit vom Wegaufnehmer entfernt und damit der gleiche Zustand erreicht wird, als ob der Schwimmer nicht im Strahlungsfeld des Wegaufnehmers stünde.When the magnetic displacement transducer works, it can happen that the floating swimmer is too far away from it Displacement transducer is removed and the same state is achieved as if the swimmer was not in the radiation field of the displacement transducer would stand.
Durch dieses Verhalten ergeben sich in der Punktion einer Licht-This behavior results in the puncture of a light
schranke bzw. eines magnetischen Wegaufnehmers große Unsicherheiten. Dies führt dazu, daß nachgeschaltete Punktionen ihren Dienet versagen können.barrier or a magnetic displacement transducer great uncertainties. This leads to the fact that downstream punctures their Serve can fail.
Die vorliegende Neuerung vermeidet diese lachteile· Sie !Teuerung ist dadurch gekennzeichnet, daß der Schwimmer in dem Gehäuse auf einem Führungestab gleitet, und daß er in seinem Inneren ein lichtundurchlässiges Blech trägt.The present innovation avoids these disadvantages · you! is characterized in that the float slides in the housing on a guide rod and in that it slides inside carries an opaque sheet metal.
Die Neuerung ist beispielsweise in der Zeichnung dargestellt. In dem Glasgehäuse 1 befindet sich der hohle Schwimmer 2, der ebenfalls aus Glas ist und eine in Richtung der Längsachse des Glasgehäuses verlaufende, durchgehende zentrische Bohrung aufweist.The innovation is shown, for example, in the drawing. In the glass housing 1 is the hollow float 2, the is also made of glass and has a continuous central bore running in the direction of the longitudinal axis of the glass housing.
Dieser Schwimmer 2 gleitet auf einem Führungsstab 3, der an seinem oberen und unteren Ende durch beliebige geeignete Vorrichtungen, z. B. durch Qiierstäbe 4 in seiner Position gehalten wird.This float 2 slides on a guide rod 3, the its upper and lower ends by any suitable device, e.g. B. held in position by Qiierststab 4 will.
Im Inneren trägt der Schwimmer ein Blech 5» das bei Verwendung des Schwimmers in Kombination mit einem magnetischen Wegaufnehmer aus ferromagnetische!!! Material besteht.Inside the float carries a sheet metal 5 »which, when the float is used in combination with a magnetic displacement transducer made of ferromagnetic !!! Material consists.
Das Element 6 ist im Falle von Lichtschranken die Lichtquelle, das Element 7 der Lichtempfän^er. Bei magnetischen Hegelvorrichtungen stellt 6 den magnetischen Wegaufnehmer dar.In the case of light barriers, element 6 is the light source, element 7 is the light receiver. In the case of magnetic levitation devices, 6 represents the magnetic displacement transducer.
