Description

Die Erfindung bezieht sich auf eine Registriervorrichtung für Meßgeräte od. dgl., bei der eine an Spannung liegende Elektrode, meist ein dünner Wolframdraht, einen dem zu markierenden wertentsprechenden Punkts aus einem dünnen Metallbelag eines Registrierplap,iers herausbrennt. Für solche Zwecke kann das gleiche Papier verwendet werden wie für Papierkondensatoren mit aufgedampftem Belag. The invention relates to a recording device for measuring devices or the like, in which a live electrode, usually a thin tungsten wire, a point corresponding to the value to be marked made of a thin metal coating a registration board that burns out. For such purposes, the same paper can be used can be used as for paper capacitors with a vapor-deposited coating.

Versuche haben gezeigt, daß beispielsweise die aufgezeichnete Kurve oft eine größere Strichstärke hat als erwünscht ist, daß die Ränder des Striches mitunter nicht genügend scharf sind und daß sich an einzelnen Stellen der Kurve, oft unglücklicherweise an den für die Ablesung maßgebenden Umkehrstellen, Reste des ausgebrannten Meballbelages, wahrscheinlich Metalloxyde, festsetzen und dadurch die Genauigkeit der Ablesung beeinträchtigen. Diese Reste setzen sich im Laufe der Registrierung an der Elektrode fest und lagern sich von Zeit zu Zeit auf dem Registrierpapier ab. Tests have shown that, for example, the recorded curve often has a larger line width than is desired that the edges of the line are sometimes not sharp enough and that at individual points on the curve, often unfortunately at the reversal points, which are decisive for the reading, residues of the burnt-out meball coating, probably metal oxides, and thereby affect the accuracy of the reading. These remnants settle in the course of the Registration on the electrode and settle on the registration paper from time to time away.

Die Erfindung beseitigt diese Mängel und ergibt eine scharfrandige, genügend dünne und von Absetzungen freie Registrierung. ErfiNdungs,gemläß wird der aus der Elektrode und Metallbefag be stehende Kontakt mit an sich bekannten Funkenlöschmitteln versehen. Dem Kontakt wird beispielsweise ein kleiner Kondensator parallel geschaltet, der den t5:ffnungsfunken schluckt, und dem Ganzen ein Widerstand vorgeschaltet, der den Energienachschub aus der Spannungsquelle begrenzt. Doch können. alle die anderen bekannten Mittel zur Unterdrückung des Kontaktfeuers bei Schaltern, Relais od. dgl. verwendet werden. The invention eliminates these deficiencies and results in a sharp-edged, sufficiently thin registration free of deposits. According to the invention, the from the electrode and Metallbefag be standing contact with known spark extinguishers Mistake. For example, a small capacitor is connected in parallel to the contact, who swallows the t5: opening spark and precedes the whole thing with a resistor, which limits the energy supply from the voltage source. But can. all of them other known means for suppressing contact fire in switches, relays or the like. Can be used.

Die Erfindung wird an Hand des in der Zeichnung dargestellten Schaltbeispiels näher erläutert. The invention is based on the circuit example shown in the drawing explained in more detail.

Auf einem mit Metall bedampfen Registrierstreifen I, auf dessen Metallbelag eine an den einen Pol einer Stromquelle angeschlossene Kontaktrolle 2 läuft, wird mittels eines dünnen Wolframdrahtes 3, der beispielsweise von einem Meßgerät geführt ist, eine Kurve geschrieben. Dieser Draht 3 islt über einen Widerstand 4 an den anderen Pol der Stromquelle angeschlossen. Zu den Teilen 2, 3 liegt ein kleiner Kondensator 5 parallel. Größenordnüngsmäßig wird man bei einer Spannung von etwa ao V einen Widerstand mit etwa 300. bis 400 Ohm und einen Kondensator von einigen Tausend Pikofarad verwenden. Da die Strombelastung -der Elektrode sehr klein ist, können auch der Widerstand und der Kondensator sehr klein gehalten werden lassen sich also beispielsweise leicht im Meßgerät selbst unterbringen. On a register strip I vaporized with metal, on its metal coating a contact roller 2 connected to one pole of a power source is running by means of a thin tungsten wire 3, which is guided, for example, by a measuring device is written a curve. This wire 3 islt over a resistor 4 to the connected to the other pole of the power source. For parts 2, 3 there is a smaller one Capacitor 5 in parallel. In terms of magnitude, one becomes at a voltage of about ao V a resistor of about 300th to 400 ohms and a capacitor of a few Use a thousand picofarads. Since the current load of the electrode is very small, the resistor and the capacitor can also be kept very small So, for example, easily accommodate in the measuring device itself.
