Abstract

Ein Druckbehälter (10, 50) mit einem in Längsrichtung des Druckbehälters beweglichen Kolben (13, 51), wobei zur Positionsbestimmung des Kolbens (13, 51) in dem Druckbehälter (10, 50) wenigstens an der Wandung des Druckbehälters (10, 50) eine Elektrode als Bestandteil einer Messanordnung angebracht ist und die durch die Änderung der Position des Kolbens (13, 51) im Druckbehälter (10, 50) erzeugte Änderung eines durch Zufuhr von elektrischer Energie erzeugten elektrischen Wechselfeldes in der Messanordnung gemessen und daraus die jeweilige Position des Kolbens (13, 51) im Druckbehälter (10, 50) bestimmt wird, ist dadurch gekennzeichnet, dass die an der Wandung des aus einem aus harzimprägnierten Fasern aufgebauten, faserverstärkten Kunststoff bestehenden Druckbehälters (10, 50) angeordnete Elektrode aus einem auf ein als an der Wandung (11) des Druckbehälters (10, 50) angebrachte flächige Anordnung (15) ausgebildetes Basismaterial genähten oder gestickten Leiter (23) besteht und die andere Elektrode der Messanordnung von dem Kolben (13, 51) oder einem weiteren, in Umfangsrichtung des Druckbehälters (10, 50) auf dem Basismaterial versetzt aufgestickten oder aufgenähten elektrischen Leiter (20) gebildet ist.

Figure imgaf001
A pressure vessel (10, 50) having a piston (13, 51) which is movable in the longitudinal direction of the pressure vessel, at least on the wall of the pressure vessel (10, 50) for determining the position of the piston (13, 51) in the pressure vessel (10, 50). an electrode is mounted as part of a measuring arrangement and the change in the position of the piston (13, 51) in the pressure vessel (10, 50) produced change in an electrical alternating field generated by the supply of electrical energy measured in the measuring arrangement and from there the respective position of Piston (13, 51) in the pressure vessel (10, 50) is determined, is characterized in that on the wall of the built of a resin impregnated fibers, fiber reinforced plastic existing pressure vessel (10, 50) arranged electrode from a on a than the wall (11) of the pressure vessel (10, 50) attached planar arrangement (15) formed base material sewn or embroidered conductor (23) best ht and the other electrode of the measuring arrangement of the piston (13, 51) or another, in the circumferential direction of the pressure vessel (10, 50) offset on the base material embroidered or sewn on electrical conductor (20) is formed.
