Description

Kompensierendes Meßgerät Die Erfindung betrifft eine Einrichtung zur Einstellung eines Kompensators in Abhängigkeit von der Stellung eines Zeigers, bei welcher der Zeiger zeitweilig senkrecht zur Ausschlagsrichtung gegen den einen oder anderen von zwei Winkelhebeln gedrückt wird, die über mechanische - Zwischenstücke ein Verstellorgan einstellen. ' Gemäß der Erfindung ist das Verstellorgan als eine hin und her gehende Schiene oder als eine zur Zeigerachse vorzugsweise koaxial" drehbar gelagerte Scheibe mit einer Verzahnung ausgebildet, in welche zwei an den mechanischen Zwischenstücken befestigte Schaltklinken eingreifen. Wird dabei in bekannter Weise die zur Kompensation dienende Gegenkraft durch Änderung der Spannung einer Feiler erzeugt, so kann ferner gemäß der Erfindung die Richtkraftfeder des Meßinstrumentes mit ihrem 'einen Ende an der Kompensationsscheibe selbst befestigt sein. Durch diese Anordnungen wird ein besonders einfacher, konstruktiver Aufbau_ der Kompensationsvorrichtung erreicht.Compensating measuring device The invention relates to a device for Adjustment of a compensator depending on the position of a pointer, at which the pointer is temporarily perpendicular to the direction of deflection against the one or the other is pressed by two angled levers, via mechanical - intermediate pieces adjust an adjuster. 'According to the invention, the adjusting member as a rail going back and forth or as a rail preferably coaxial to the pointer axis " rotatably mounted disc formed with a toothing, in which two to the Engage pawls attached to mechanical spacers. Is used in as is known, the counterforce used for compensation by changing the voltage a Feiler generated, so can furthermore according to the invention, the directional force spring of the Measuring instrument with its' one end attached to the compensation disc itself be. These arrangements result in a particularly simple, constructive structure. reached the compensation device.

In der Zeichnung ist ein Ausführungsbeispiel dargestellt. Der an einem ortsfesten Teil angelenkte Fallbügel f wird in bekannter Weise, z. B. durch einen Motor, angetrieben und vollführt periodisch auf- und abwärts gehende Bewegungen. Ändert sich die Meßgröße, so wird die Kompensation gestört und der'Zeiger weicht aus der dargestellten Stellung ab und kommt über ein Zwischenstück bekannter Form, hier den Winkelhebel a oder b, die -um ortsfeste Achsen drehbar gelagert sind, zu stehen. Beim folgenden Niedergang des Fallbügels und - damit des elastischen Zeigers bekannter Art macht der betreffende Winkelhebel numehr eine nickende Bewegung. ' An seinem freien Hebelarm befindet sich je eine Schaltklinke c bzw. d. Die Schaltklinken greifen in den gezahnten Rand einer Scheibe g. -Die Scheibe wird. dadurch in rechts- öder linksläufigem Sinne gedreht, je nachdem ob die Meßgröße sich nach oben oder unten verändert. Die Scheibe trägt nun unmittelbar den eigentlichen in. der Zeichnung nicht dargestellten Kompensator.An exemplary embodiment is shown in the drawing. The one on one fixed part hinged drop bracket f is in a known manner, for. B. by a Motor, driven and performs periodic upward and downward movements. If the measured variable changes, the compensation is disturbed and the pointer deviates from the position shown and comes via an intermediate piece of known shape, here the angle lever a or b, which are rotatably mounted about fixed axes, too stand. With the following decline of the drop bar and - with it the elastic pointer known type makes the angle lever concerned numehr a nodding movement. ' A pawl c or d is located on its free lever arm. The ratchets grip into the toothed edge of a disc g. -The disc will. thereby in legal or counter-clockwise, depending on whether the measured variable is up or changed below. The disk now immediately bears the actual one in the drawing compensator not shown.

Will man mechanisch kompensieren, so kann das in der Weise geschehen, daß- etwa das äußere Ende h der-Richtkraftfeder eines Drehspulentneßwerkes mit der Scheibe fest verbunden ist: -Die Drehung der Scheibe spannt oder entspannt dann diese Feder so lange, bis ihr mechanisches Drehmoment dem elektrischen Drehmoment der Meßwerkspule in der Mittelstellung zwischen a und b das Gleichgewicht hält: In dieser Stellung geht der Zeiger wieder frei, und die Scheibe kommt bis zur' nächsten Schwankung der Meßgröße zum Stillstand. In sinngemäß ähnlicher Weise läßt sich mit der Scheibe auch der Richtkraftträger anderer Meßwerke, beispielsweise einer Membran oder Waage eines hydraulischen oder pneumatischen Instrumentes o. dgl., kuppeln. Soll elektrisch kompensiert werden, wie es bei Thermoclementen häufig erwünscht ist, so treibt die Scheibe g den bekannten Schiebe-oder Schleifwiderstand an, durch den die die Thermokraft kompensierende Gegenspannung verändert wird.If you want to compensate mechanically, this can be done in the way that about the outer end of the directional force spring of a Drehspulentneßwerkes with the Disc is firmly connected: -The rotation of the disc then tensions or relaxes this spring until its mechanical torque equals electrical torque the measuring coil in the middle position between a and b keeps the equilibrium: In this position the pointer goes free again and the disc moves to the next one Variation in the measured variable to a standstill. In a similar manner, you can use the disk also the directional force carrier of other measuring mechanisms, for example a membrane or the balance of a hydraulic or pneumatic instrument or the like., couple. Intended to be electrically compensated, as is often desired with thermocouples, the disk g drives the known sliding or drag resistance through which the counter-voltage compensating for the thermal force is changed.

Die Stellung der Scheibe g ist unmittelbar ein Maß für die Meßgröße. Sie kann infolgedessen direkt mit Zeiger z und Skala s oder einer Registriervorrichtung für die Meßgröße versehen werden.The position of the disk g is a direct measure of the measured variable. As a result, it can be used directly with the pointer z and scale s or a recording device for the measurand.

Es ist nicht erforderlich, daß der Kompensationsträger g die Form einer runden Scheibe besitzt. In manchen Fällen ist ein Kreisausschnitt dafür ausreichend. Auch eine gezahnte Stange ist verwendbar, die statt einer drehenden eine Hinundherbewegung ausführt.It is not necessary that the compensation carrier g has the shape a round disc. In some cases a section of a circle is sufficient for this. A toothed bar can also be used, which has a reciprocating motion instead of a rotating one executes.
