Description
Elektrometer zur Bestimmung des Verlaufs, von elektrischen Potentialflächen Verfahren, luftelektrische Potentialflächen in der Natur mit Hilfe eines Elektrometers und eines davon getrennten Kollektors zu bestimmen, sind bereits bekannt. Alle diese Verfahren benutzen einen Elektrometer oder einen sonstigen Spannungsanzeiger, der mit einem davon getrennten Kollektor verbunden ist. Es ist bekannt, daß jeder dieser beiden Teile die Potentialflächen in seiner Nähe stört und außerdem eine unerwünschte hohe Kapazität der Gesamtanordnung hervorruft, die durch geeignet hohe Aufladegeschwindigkeit der Kollektoren wieder' aufgehoben werden muß; außerdem leidet darunter noch die Bequemlichkeit des Arbeitens. Beide Nachteile will die nachstehend beschriebene Erfindung verringern dadurch, daß sie einen Teil des Elektrometers selbst durch Form oder Eigenschaften so ausbildet, daß er als Kollektor wirkt. Einmal kann dadurch die Kapazität stark herabgesetzt werden, andererseits fallen die Deformationen der Äquipotentialflächen durch den Kollektor und seine leitende Verbindung mit dem Elektrometer fort. Nebenbei wird noch die Bequemlichkeit des Arbeitens erhöht, da sich der ganze _Apparat äußerst kompendiös bauen läßt. Eine beispielsweise Ausführung zeigt Abb. i. Hier ist a ein stabförmiger Körper, der durch Spitzenwirkung oder Aktivierung an seinem Ende als Kollektor wirkt. Als Gegenkollektor dient der nach unten gerichtete Zeiger b, der ebenfalls an seiner Spitze aktiviert ist, so daß bei passender Anordnung das Potentialgefälle zwischen zwei Flächen gemessen wird, deren Abstand voneinander durch die räumliche Entfernung der Enden von Stab a und Zeiger b gegeben ist. Eine ähnliche Anordnung zeigt Abb. 4, wo der Zeiger a als Kollektor analog dem eben beschriebenen ausgebildet ist, und Abb. 3 bei der mit den beiden Elektroden, zwischen denen die Elektrometernadel sich bewegt, zwei stabförmige Kollektoren verbunden sind, so daß auch hier das Potentialgefälle zwischen den beiden Punkten gemessen wird, die durch die Enden der beiden Kollektorenstäbe-bezeichnet sind. Eine gleiche Anordnung in Form eines Quadrantenelektrometers zeigt Abb. 2.Electrometers for determining the course of electrical potential surfaces, methods to determine air-electrical potential surfaces in nature with the help of an electrometer and a collector separated therefrom are already known. All of these methods use an electrometer or other voltage indicator connected to a separate collector. It is known that each of these two parts disturbs the potential surfaces in its vicinity and also causes an undesirably high capacity of the overall arrangement, which must be canceled again by a suitably high charging speed of the collectors; in addition, the convenience of working suffers. The invention described below aims to reduce both disadvantages by designing a part of the electrometer itself by shape or properties in such a way that it acts as a collector. On the one hand, this can greatly reduce the capacitance, on the other hand, the deformations of the equipotential surfaces caused by the collector and its conductive connection with the electrometer are eliminated. In addition, the convenience of working is increased, since the entire apparatus can be built extremely compensated. An example embodiment is shown in Fig. I. Here, a is a rod-shaped body that acts as a collector through tip action or activation at its end. The counter-collector is the downward pointing pointer b, which is also activated at its tip, so that with a suitable arrangement the potential gradient between two surfaces is measured, the distance between which is given by the spatial distance between the ends of rod a and pointer b . A similar arrangement is shown in Fig. 4, where the pointer a is designed as a collector analogous to the one just described, and Fig. 3 in which two rod-shaped collectors are connected to the two electrodes between which the electrometer needle moves, so that here too Potential gradient is measured between the two points, which are designated by the ends of the two collector rods. The same arrangement in the form of a quadrant electrometer is shown in Fig. 2.
