Description
Die Erfindung bezieht sich auf einen Kondensator zur Verwendung in einem kapazitiven Flüssigkeitspegelmeßsystem, in welchem ein langgestrecktes inneres Armaturelement von einem röhrenförmigen mittleren Armaturelement umgeben ist, das wiederum von einem rohrförmigen äußeren Element umgeben ist-, und die drei Elemente koaxial zueinander abgestützt sind, wobei die inneren und äußeren Elemente miteinander elektrisch verbunden und von dem mittleren Element isoliert sind und Durchgänge zum Durchfluß der Flüssigkeit in die Zwischenräume zwischen den Elementen vorgesehen sind.The invention relates to a capacitor for use in a capacitive liquid level measuring system, in which an elongated inner armature element is separated from a tubular central one Fitting element is surrounded, which in turn is surrounded by a tubular outer element, and the three elements are supported coaxially with each other, the inner and outer elements with each other are electrically connected and isolated from the central element and have passages for flow through of the liquid are provided in the spaces between the elements.
Erfindungsgemäß bestehen die Mittel zur koaxialen Abstützung der drei Elemente und zur elektrisehen Verbindung des inneren und äußeren Elementes unter ihrer Isolierung von dem mittleren Element an jedem Ende aus einer Metallendkappe mit einem Kopfteil mit großem Durchmesser, der in dem betreffenden Ende des äußeren Elementes gehalten ist, und mit einem nach innen ragenden Schaftteil, der beispielsweise durch Verschraubung an dem betreffenden Ende des inneren Elementes befestigt ist, und aus zwei Isolierscheiben zur Abstützung des mittleren Elementes, von denen eine erste Isolierscheibe zwischen der Endfläche des mittleren Elementes und der Oberfläche des Kopfes eingesetzt ist, während die andere Scheibe von dem Schaftteil der Kappe nach außen ragt und mit ihrem äußeren Umfang gegen die innere zylindrische Fläche des mittleren Elementes stößt.According to the invention, there are means for the coaxial support of the three elements and for electrical viewing Connection of the inner and outer elements under their isolation from the middle element each end of a metal end cap with a large diameter head held in the respective end of the outer member, and with an inwardly protruding shaft part, which is for example screwed to the relevant End of the inner element is fixed, and two insulating washers to support the middle one Element, of which a first insulating washer between the end face of the middle element and the Surface of the head is inserted, while the other disc from the shaft part of the cap after protrudes outside and with its outer circumference against the inner cylindrical surface of the central element bumps.
Vorteilhaft besitzt jede Endkappe einen in ihr ausgebildeten axialen Durchgang, der mit einem Radialdurchgang in Verbindung steht, welcher in dem inneren Element zum Eintritt der Flüssigkeit in dem Raum zwischen dem inneren und mittleren Element ausgebildet ist.Each end cap advantageously has an axial passage formed in it, which with a radial passage is in communication, which is in the inner element for entry of the liquid in the Space is formed between the inner and middle elements.
Gemäß einer weiteren vorteilhaften Ausbildung ist ein elektrischer Leiter, der mit dem mittleren Element verbunden ist, durch die radialen und axialen Durchgänge aus einem Ende des Kondensators herausgeführt. According to a further advantageous embodiment, an electrical conductor is connected to the middle element is connected, led out through the radial and axial passages from one end of the capacitor.
Einer der wesentlichsten Vorteile des verbesserten Kondensators besteht in der Einfachheit und in der Wirtschaftlichkeit seiner Herstellung, die als einfache Serienherstellung durchgeführt Averden kann. Dieses wird durch die Gleichheit der Stütz\'orrichtungen an den beiden Enden erreicht. Weiterhin !«steht die Möglichkeit, identische Stützvorrichtungen zu verwenden, welche außerdem noch sehr einfach und leicht herzustellen sind und wenig Material benötigen. Man kann so Kondensatoren von verschiedener Länge herstellen, wobei sowohl das eine als auch das andere Ende desselben in die Flüssigkeit eingetaucht werden kann. Der äußere und innere Teil wird an die Erde Kondensator zur Pegelmessung in Flüssigkeiten One of the most important advantages of the improved capacitor is the simplicity and economy of its manufacture, which can be carried out as simple mass production. This is achieved by the equality of the support devices at the two ends. Furthermore! «There is the possibility of using identical support devices, which are also very simple and easy to manufacture and require little material. It is thus possible to manufacture capacitors of various lengths, one end as well as the other of which can be immersed in the liquid. The outer and inner part is connected to the earth capacitor for level measurement in liquids

angeschlossen und diese Teile, welche den mittleren rohrförmigen Teil vollständig umgeben, sorgen für eine Abschirmung des Kondensators und für einen wirksamen Schutz gegen Störungen von hoher Frequenz.connected and these parts, which completely surround the central tubular part, ensure a shielding of the capacitor and for effective protection against interference of high Frequency.
Der Kondensator führt sehr genaue und sehr empfindliche Messungen bei sogar sehr niedrigen wie auch bei sich sehr schnell ändernden Pegelständen aus.The capacitor performs very accurate and very sensitive measurements at even very low levels of like even if the water level changes very quickly.
Im folgenden soll im Zusammenhang mit der Zeiclmung ein erfindungsgemäßes Ausführungsbeispiel l>eschrieben werden. Die Figur zeigt einen Schnitt des fertig zusammengesetzten Kondensators, der teilweise abgebrochen dargestellt ist.In the following, an exemplary embodiment according to the invention is intended in connection with the drawing l> be written. The figure shows a section of the fully assembled capacitor, which is shown partially broken off.
Der Kondensator besteht aus einem äußeren Gehäuserohr 10 und einem mittleren Rohrelement 11 sowie aus einem inneren Teil 12, welches die Form einer zylindrischen Stange hat. Um diese drei Teile 10, 11, 12 zusammenzuhalten, befindet sich an den beiden Enden dieser Vorrichtung eine Halterung in Form eines metallischen Stopfens 13, welcher pilzförmig ausgebildet ist und einen Kopf 14 hat, um welchen bei 31 die Enden des äußeren Rohres zusammengefügt sind.The condenser consists of an outer housing tube 10 and a central tube element 11 as well as an inner part 12 which is in the form of a cylindrical rod. In order to hold these three parts 10, 11, 12 together, a holder in the form of a metallic plug 13, which is mushroom-shaped and has a head 14 around which the ends of the outer tube are joined at 31, is located at the two ends of this device.
