Abstract

Bei einem Verfahren und einer Einrichtung zum Bestim­ men des atmosphärischen Außendrucks mittels eines elek­ tropneumatischen Membrandosenstellers (1), dessen bewegliche Arbeitsmembran (4) einerseits mit einem über Steuerventile (8, 10) veränderbaren Steuerdruck in einem Steuerdruckraum (2) sowie andererseits mit einer hierzu in Stellerausfahrrichtung entgegengerichteten Kraft einer Membrandosenfeder (7) beaufschlagt und mit einem Be­ wegungsanschlag (6) für ein emernes steuerbares Gestänge (13), insbesondere eines Drosselgestänges einer Verbren­ nungsmaschine, mit einer zur Membrandosenfeder (7) in Stellereinfahrrichtung entgegengerichtet wirkenden Gestän­ gefeder (15) verbunden ist, wird unter Vermeidung eines ge­ sonderten Drucksensors der Membrandosensteller (1) selbst zum Bestimmen des Außendrucks benutzt. Zu diesem Zweck werden die Steuerventile (8, 10) geschlossen und dann die sich bei Belastung sowie Entlastung durch das externe Ge­ stänge (13) ergebenden Hübe gemessen. Hieraus wird an­ schließend der Außendruck bestimmt.
