Description
Einrichtung zur Herbeiführung von Kontaktbetätigungen elektrischer Meßgeräte an beliebiger, aber vorgeschriebener Stelle des Bießbereichs. Die den Gegenstand der Erfindung bildende Einrichtung hat die Aufgabe, mit Hilfe eines Meßwerks, z. B. eines Fernthermometers, Kontakte zu betätigen, die je nach dem Verlauf eines Prozesses an den verschiedenartigsten Stellen des Meßbereiches ansprechen müssen. Schleifkontakte kommen hierbei wegen der geringfügigen Drehkräfte derartiger Meßwerke nicht in Frage, und nebenein.-andergelagerte, etwa mit Hilfe eines Fallhebels zu betätigende Kontakte verhindern durch ihre eigene räumliche Ausdehnung die beliebige Verteilung der Kontakte, abgesehen davon, daß in manchen' Fällen die lange Zeitdauer zwischen zwei Hebelschlägen nicht in Kauf genommen werden kann.Device for bringing about contact actuations electrical Measuring devices at any, but prescribed, point in the biting area. The den The object of the invention forming device has the task, with the help of a measuring mechanism, z. B. a remote thermometer to operate contacts, depending on the course of a Process must respond at the most diverse points in the measuring range. Sliding contacts come here because of the slight torsional forces of such measuring mechanisms out of the question, and juxtaposed, for example with the help of a drop lever actuating contacts prevent arbitrary ones by their own spatial expansion Distribution of contacts, apart from the fact that in some cases the long duration cannot be accepted between two lever strokes.
Erfindungsgemäß wird die bei Meßinstrumenten an sich bekannte Einrichtung der von Hand verstellbaren Kontakte benutzt, jedoch in der Weise, daß diese Verstellung mit Hilfe eines besonderen Hilfsmeßwerks erfolgt.According to the invention, the device known per se for measuring instruments the manually adjustable contacts used, but in such a way that this adjustment takes place with the help of a special auxiliary measuring mechanism.
Die Abb. i veranschaulicht in schematischer Darstellung das Wesentliche der Erfindung. Es bedeutet darin z den Zeiger eines Meßwerks, dessen bewegliches System d, -etwa eine Drehspule - sich um die Achse a, dreht. Der um die gleiche mathematische Achse, jedoch in besonderer Lagerung um die Systemachse a, drehbare Hebelarm h trägt eine Kontaktgabel mit den Kontakten c" c_, die über Leitungen L" 1, zu Relais oder sonstigen Schaltvorrichtungen geführt sind. dz ist das bewegliche System des Hilfsmeßwerks, z. B. ebenfalls eine Drehspule, deren Bewegung dadurch von außen gesteuert wird, daß dem Meßwerk verschiedenartige Stromstärken zugeführt werden können. Letzteres kann z. B. in bekannter Weise durch einen von dem Uhrwerk i4 verschiedenartig geschalteten Widerstand y geschehen.Fig. I illustrates the essence of the invention in a schematic representation. There it means z the pointer of a measuring mechanism, the moving system d, - for example a rotating coil - rotates around the axis a. The lever arm h , which can be rotated around the same mathematical axis, but in a special bearing around the system axis a, carries a contact fork with the contacts c "c_, which are led via lines L" 1 to relays or other switching devices. dz is the moving system of the auxiliary measuring mechanism, e.g. B. also a moving coil, the movement of which is controlled from the outside by the fact that various currents can be supplied to the measuring mechanism. The latter can e.g. B. done in a known manner by a resistor y connected differently from the movement i4.
An Stelle der Kontaktgabe mit festen Abständen c" c2 können verschiedenartige Gabelgrenzen hergestellt werden, dadurch, daß die beiden Kontakte sich einzeln, je an einem besonderen Hilfsmeßwerk befinden.Instead of making contact with fixed distances c "c2, various Fork limits are made by the fact that the two contacts are individually, are each located on a special auxiliary measuring mechanism.
Im Gegensatz zu den schon erwähnten Mißlichkeiten, bei Schreibgeräten mit Fallbügel feste Kontaktabschnitte anzubringen, läßt sich ntmmehr gemäß der Erfindung eine sehr wertvolle Kontrolle der zu überwachenden Vorgänge mit der Regulierung verbinden. Man kann nämlich mit Hilfe eines gleichen Fallbügels f (Abb. z) nicht nur das Spiel des Zeigers z verfolgen, sondern man`erhält auch, indem man die Kontakte c, und c. gleichzeitig in Form von Druckzeigern z" z, auslaufen läßt, eine Markierung der jeweiligen Sollstellung und damit eine Kontrolle über den vorschriftsmäßigen Ablauf des Vorganges. Aus der in Abb. 2 beispielsweise dargestellten Markierung ist also zu ersehen, daß bei k, innerhalb der planmäßigen, Gabelstellung und in gleicher Weise bei k= bei der nun veränderten Gabelstellung Kontaktstellung eintreten wird, daß aber nach dem Kontaktschluß k.. ein jäher, nicht vorgesehener Abfall der Temperatur, der auf irgendeine Störung zurückzuführen war, eingetreten ist.In contrast to the previously mentioned inconveniences with writing implements Attaching fixed contact sections with drop stirrups can be done according to the invention a very valuable control of the processes to be monitored with the regulation associate. You cannot use the same drop bracket f (Fig. Z) only follow the play of the pointer z, but you can also get it by looking at the contacts c, and c. at the same time in the form of pressure pointers z "z, can run out, a marking the respective debit position and thus a control over the regular Course of the process. From the marking shown in Fig. 2, for example it can therefore be seen that at k, within the planned fork position and in in the same way at k = in the now changed fork position contact position occur becomes that but after the contact closure k .. a sudden, unexpected drop in the Temperature caused by some malfunction has occurred.
