Description

Einrichtung zur Fernregistrierung von Seismographen und Erschütterungsmessern. jeder moderne Seismograph ist mit einer Dämpfungsvorrichtung (Luft- oder Flüssig keitsdämpfung, abgesehen von der magne-. tischen Dämpfung, die hier nicht in Frage kommt) versehen, bei der sich eine oder mehrere mit dem Seismographen verbundene Flächen in bezug auf- feststehende Flächen bewegen. Es sollen nun bei der vorliegenden Einrichtung diese Flächensysteme aus Metallplatten oder metallisierten Platten hergestellt, als Systeme voneinander elektrisch isoliert und in ihren Abmessungen gegeneinander so gewählt werden, daß bei einer Bewegung des Pendelkörpers und somit auch der damit verbundenen beweglichen Flächen der Dämpfungsvorrichtung, deren Abstand von den festen Flächen desselben abweicht, was naturgemäß gleichphasig mit der Pendelbewegung geschieht. Eine solche Anordnung ist damit zugleich als veränderlicher Kondensator anzusehen. In der Abbildung stellt i den Pendelkörper dar, 2 das bewegliche Plattensystem, 3 das Gelenk, in dem der Hebelarni von 2 mit denl Verbindungsarm von i zusammentrifft, q. ist das feste Plattensystem. Befindet sich nun z. B. Öl zwischen den Plattensystemen 2 und q., so stellt die Anordnung 2, 3, 4 eine in der Literatur bekannte Form der Dämpfungseinrichtung vor. Nunmehr wird die Eigenschaft- dieses Systems, zugleich ein veränderlicher Kondensator zu sein, in der Wdise benutzt, daß dieser Kondensator beispielsweise in eine K,tpazitätsmeßbrückenr anordnung eingeschaltet wird. In der Abbildung ist 5 ein Drehkondensator zum Abgleichen, 6 und 7 sind feste Kondensatoren, 8 ist ein Galvanometer, 9 ein Transformator und io eine Wechselstromquelle geringer Energie. Ändert sich nun durch Bewegung von i die Lage der Fläche 2 gegen q., so wird, wenn vorher der Brückenstrom durch 5 auf Null abgeglichen war, nunmehr das Galvanometer 8 einen Ausschlag zeigen, der in rechnerisch streng erfaßbarer Beziehung iur Verschiebung von 2 gegen q. und damit von i gegen die Ruhelage steht. Auf diese Weise ist es aber möglich, die durch irgendeine Bodenbewegung hervorgerufene Pendelbewegung mit Hilfe dieses speziell angegebenen Dämpfers elektrisch zu registrieren.Device for remote registration of seismographs and vibration meters. every modern seismograph is equipped with a damping device (air or liquid damping, apart from the magnetic. table cushioning, which is out of the question here comes), in which one or more connected to the seismograph Move surfaces in relation to fixed surfaces. It should now be with the present Set up these surface systems made of metal plates or metallized plates, as systems electrically isolated from one another and from one another in their dimensions be chosen so that with a movement of the pendulum body and thus also the one with it connected movable surfaces of the damping device, the distance of which from the solid surfaces of the same deviates, which is naturally in phase with the pendulum movement happens. Such an arrangement is thus also a variable capacitor to watch. In the figure i represents the pendulum body, 2 the movable plate system, 3 the joint in which the lever arm of 2 meets the connecting arm of i, q. is the fixed plate system. Is now z. B. Oil between the plate systems 2 and q., The arrangement 2, 3, 4 represents a form known in the literature the Damping device before. Now the property of this system becomes at the same time to be a variable capacitor, in the Wdise that this capacitor is used is switched on, for example, in a K, tpacitysmeßbrückenr arrangement. In the Figure 5 is a variable capacitor for balancing, 6 and 7 are fixed capacitors, 8 is a galvanometer, 9 is a transformer and io is an alternating current source Energy. If the position of surface 2 changes towards q. By moving i, then if the bridge current was previously adjusted to zero by 5, now that Galvanometer 8 show a deflection in a strictly computational relationship i for shifting 2 against q. and so stands from i against the rest position. To this It is possible, however, to use the pendulum motion caused by any movement of the ground to register electrically with the help of this specially specified damper.

Statt der Meßbrückenanordnung kann selbstverständlich auch irgendeine andere Meßanordnung gewählt werden, wie diese in der Wechselstrom- und Hochfrequenztechnik gebräuchlich sind, also z. B. etwa auch ein Hochfrequenzschwingungskreis zu drahtloser übefnüttlung. Um den Plattensystemen ein geringeres Gewicht zu geben, was namentlich bei Erschütterungsmessern u. a. auch aus Transportrücksichten von Wert ist, kann man auch die Platten z. B. aus Kork herstellen, sie galvanisieren oder in diese Korkplatten Drähte in Windungen einbetten.Instead of the measuring bridge arrangement, any one can of course also be used other measuring arrangements can be selected, such as those used in alternating current and high-frequency technology are common, so z. B. about a high-frequency oscillating circuit too wireless overfilling. In order to give the plate systems a lower weight, something specifically for vibration meters, etc. is also of value for transport considerations, can one also the plates z. B. made of cork, galvanize them or in them Cork sheets embed wires in turns.
