Description
Einrichtung zur Abtastung des Zeigerausschlages von Meßgeräten Bei der Anwendung von Meßgeräten ist es häufig notwendig, die Erreichung eines bestimmten Zeigerausschlages durch Kontakte zu signalisieren. Man verwendet hierfür häufig, insbesondeie bei schwachen Meßgeräten, eine fremde Energiequelle, die durch mechanische Einrichtungen den Zeigerausschlag abtastet. Es ist- auch eine- Einrichtung zur Abtastung des Zeigerausschlages von Meßgeräten bekannt, bei der ein durch eine periodisch arbeitende Vorrichtung (Fallbügel) betätigter Kippschalter vorgesehen ist, der je nach der Stellung des Zeigers in einer waagerechten Lage gehalten oder nach der einen oder anderen Seite gekippt wind. und dadurch den gewünschten Schaltvorgang herbeiführt.Device for scanning the pointer deflection of measuring devices the use of measuring instruments, it is often necessary to achieve a certain To signal pointer deflection by contacts. One often uses for this especially with weak measuring devices, an external energy source that is generated by mechanical Facilities scans the pointer deflection. It is also a device for scanning of the pointer deflection of measuring devices known, in which a periodic working device (drop bar) actuated toggle switch is provided, which ever held in a horizontal position after the position of the pointer or after the one side or the other tilted wind. and thereby the desired switching process brings about.
Bei der vorliegenden Erfindung handelt es sich um die Lösung einer Spezialaufgabe, die darin besteht, das Erreichen gewisser Extremlagen einer Betriebsgröße und damit des Zeigers eines Meßgerätes zu signalisieren oder bei Erreichung dieser Extremlage im Betriebe gewisse Größen zu regeln. Außerdem soll noch die Tatsache der Überschreitung gewisser Extremlagen in einfacher Weise registriert werden. In der beiliegenden Zeichnung ist eine Einrichtung schematisch dargestellt, die diese Aufgabe in exakter und wirtschaftlich einfacher Weise zu lösen gestattet.The present invention is a solution to a Special task, which consists in reaching certain extreme situations of a company size and thus to signal the pointer of a measuring device or when this is reached Extreme situation in the company to regulate certain parameters. Also, the fact should be added the exceeding of certain extreme positions can be registered in a simple manner. In the accompanying drawing is a device is shown schematically, this Allowed to solve the task in an exact and economically simple manner.
Es ist i der bewegliche Teil eines Meßgerätes, z. B. eines Galvanometers oder eines Elektrometers, dessen Zeiger 2 sich über der Skala 3 bewegt. Die Achse q. des Meßgerätes ist nach unten fortgesetzt und trägt dort eine Scheibe 5, deren Durchmesser auf einen bestimmten Winkelbetrag vergrößert ist, so daß ein Ansatz 6 entsteht.It is i the moving part of a measuring device, e.g. B. a galvanometer or an electrometer, the pointer 2 of which moves over the scale 3. The axis q. of the measuring device is continued downward and carries a disk 5 there, whose Diameter is enlarged to a certain angular amount, so that an approach 6 is created.
Zu beiden Seiten der Scheibe 5 sind zwei Hebel ; und 8 drehbar gelagert, die durch Exzenter oder Kurvenscheiben 9 und io auf und ab bewegt werden (Wippen). Die Scheiben 9 und io befinden sich auf einer Achse i i, die über ein Zahnradgetriebe 12 und 13 und einen Schnurlauf 14 von einem Motor 15 gedreht wird, so daß die Hebel 7 und 8 sich periodisch auf und ab bewegen. Bei der Mittellage des Zeigers 2 werden sich die Wippen 7 und 8 frei bewegen können. Bei gewissen Extremlagen des Zeigers 2 wird jedoch der Ansatz 6 der Scheibe 5 die eine öder andere der beiden Wippen in ihrer Bewegung hemmen.On both sides of the disc 5 are two levers; and 8 rotatable, which are moved up and down by eccentrics or cam disks 9 and io (rocking). The disks 9 and io are located on an axis i i, which is via a gear train 12 and 13 and a line 14 is rotated by a motor 15 so that the lever 7 and 8 move up and down periodically. At the middle position of the pointer 2 will be the rockers 7 and 8 can move freely. At certain extreme positions of the pointer 2, however, the approach 6 of the disc 5 is one or the other of the two rockers inhibit their movement.
Über der Scheibe 5 befindet sich nun ein um die Achse 20 drehbar gelagerter Doppelhebel 2i, auf dem eine Quecksilberröhre 22 befestigt ist. Statt der Quecksilberröhre 22 könnten auch offene Kontakte in bekannter Weise verwendet werden. Die nach rückwärts geführten Fortsätze des Doppelhebels 21 werden von den Wippen 7 und 8 bei jeder Periode in die gezeichnete Mittellage gedrückt. Steht nun der Ansatz 6 der Scheibe 5 z. B. zwischen der Wippe B und dem linken Fortsatz 21, so wird der Doppelhebel 21 von der Wippe 7 gekippt, und es kommt an der Quecksilberröhre 22 ein. Kontakt zustande. Durch Kurvenscheiben 23 und 24, die sich auf der Achse 25 befinden, wird. der Doppelhebel2i nach einer bestimmten Zeit wieder in seine Mittellage gebracht und damit der Kontakt an der Röhre 22 unterbrochen.A rotatably mounted about the axis 20 is now located above the disc 5 Double lever 2i on which a mercury tube 22 is attached. Instead of the mercury tube 22 open contacts could also be used in a known manner. The backwards guided extensions of the double lever 21 are of the rockers 7 and 8 at each Period pressed into the drawn central position. Now is the approach 6 of the disc 5 z. B. between the rocker B and the left extension 21, the double lever 21 tilted by the rocker 7, and it arrives at the mercury tube 22. Contact conditions. By cams 23 and 24, which are on the axis 25 are located. the double lever 2i returns to its position after a certain time Brought to the central position and thus the contact on the tube 22 is interrupted.
Auf der Achse 2o des Doppelhebels 2 1 ist noch ein Zeiger 3o befestigt, der an seinem unteren Ende einen Schreibstift oder eine Schieibfeder 3 1 trägt, die auf einem Papierblatt 32 eine Kurve schreibt, welche erkennen läßt, wann der Hebel.2i von der Einrichtung gekippt wurde. Die Kurvenscheibe 32 wird über ein Getriebe 33 ebenfalls von dem Motor 15 angetrieben.On the axis 2o of the double lever 2 1, a pointer 3o is attached, which at its lower end carries a pen or a sliding spring 3 1, which writes a curve on a sheet of paper 32 which shows when the lever.2i of the device was tipped. The cam 32 is also driven by the motor 15 via a gear 33.
Durch Wahl des Übersetzungsverhältnisses der Räder 12 und 13 kann man es so einrichten, daß z. B. die Wippen 7 und 8 alle 6 Sekunden die Lage der Scheibe 5 abtasten, während die Rückführung des Doppelhebels 2i nur in a mal 6 Sekunden geschieht, wobei. a in ziemlich weiten Grenzen gewählt werden kann, so daß man es in der Hand hat, die Dauer der Kontakte der Röhre 22 den Betriebsverhältnissen anzupassen.By choosing the gear ratio of the wheels 12 and 13 can you set it up so that z. B. the rockers 7 and 8 every 6 seconds the location of the Scan disk 5, while the return of the double lever 2i only takes a times 6 seconds happens where. a can be chosen within fairly wide limits, so that one can do it has in hand to adapt the duration of the contacts of the tube 22 to the operating conditions.
Die Einrichtung gestattet also, den Gang einer Betriebsgröße am Zeiger 2 zu beobachten, gewisse Überschreitungen durch die Röhre 22 zu signalisieren oder durch die Röhre 22 die Betriebsgröße selbst zu regeln. Ferner gibt das Diagramm der Scheibe 32 einen Aufschluß über den zeitlichen Verlauf der Betriebsgröße.The device thus allows the progress of a company variable on the pointer 2 to be observed, to signal certain exceedances by the tube 22 or through the tube 22 to regulate the operating size itself. The diagram also gives the disk 32 provides information about the time course of the operating size.
