Description
Innenwandung der Membran 17 und der Trägerplatte 16 geschlossenen Raum 18 bildet, der über die öffnung ISb der Abzweigleitung 15 mit der Luftleitung 13 in Verbindung steht. Die Membran 17 besteht aus luftundurchlässiger dünner Folie und weist innenseitig eine Beschichtung 50 aus metallischen Werkstoffen auf (Fig.2). Vorzugsweise wird eine metallische Folie für die Membran 17 verwendet. Die Metallbeschichtung 50 kann durch Aufdampfen oder andere an sich bekannte Verfahren erfolgen.Inner wall of the membrane 17 and the support plate 16 forms closed space 18, which over the Opening ISb of branch line 15 with the air line 13 communicates. The membrane 17 consists of air-impermeable thin film and has a coating 50 made of metallic materials on the inside (FIG. 2). Preferably a metallic foil used for the membrane 17. The metal coating 50 can be formed by vapor deposition or other methods known per se.
Der Näherunesinitiator 40 ist an der Unterseite der Trägerplatte^ für aie Membran 17 derart befestift daß keine Beeinträchtigung der Verbindung zwischen dem Innenraum der Leitungen 13, 15 und dem Innenraum der Membran 17 erfolgt. Zur Anpassung des Abstandes des Näherungsinitiators 40 von der Innenwandung der Membran 17 bei unterschiedlichen Flüssigkeitsmengen ist der Näherungsinitiator 40 in der Trägerplatte 16 in seiner Längsrichtung verschiebbar angeordnet. Die hubverstellung des Näherungsiniäators 40 kann mittels einer Spindel oder anderen in der Zeichnung nicht dargestellten bekannten Einrichtungen erfolgen.The proximity initiator 40 is fastened to the underside of the carrier plate for aie membrane 17 in this way that no impairment of the connection between the interior of the lines 13, 15 and the interior of the membrane 17 takes place. To adjust the distance of the proximity switch 40 from the inner wall of the membrane 17 with different amounts of liquid is the proximity initiator 40 arranged in the carrier plate 16 so as to be displaceable in its longitudinal direction. The stroke adjustment of the proximity initiator 40 can be by means of a spindle or others not shown in the drawing known facilities.
