Abstract

Die Erfindung geht aus von einem pneumatischer Steller mit einem Gehäuse, das einen Boden (1) und einen Deckel (2) aufweist, einer in dem Gehäuse zwischen Boden (1) und Deckel (2) eingespannten Membran (3), einem von dem Deckel (2) und der Membran (3) umgebenen Arbeitsraum, der an eine Über- oder Unterdruckquelle anschließbar ist, einer in dem Arbeitsraum angeordneten Rückstellfeder (6), welche auf die Membran (3) einwirkt, einer aus dem Boden (1) herausragenden Stange (7), die in ihrer Längsrichtung beweglich ist und mit der Membran (3) gekoppelt ist, so dass die Stange (7) bei einer Vergrößerung des Arbeitsraums weiter aus dem Gehäuse heraus geschoben und bei einer Verkleinerung des Arbeitsraums tiefer in das Gehäuse hineingezogen wird. Erfindungsgemäß ist in dem Arbeitsraum ein magnetischer Positionsgeber (8), der mit der Membran (3) gekoppelt ist, und ein Magnetfeldsensor (9) zum Detektieren einer Verschiebung des Positionsgebers (8) angeordnet, wobei in dem Arbeitsraum zwischen der Rückstellfeder (6) und dem Magnetfeldsensor (9) ein magnetischer Schild (10) angeordnet ist.

Figure imgaf001
The invention relates to a pneumatic actuator with a housing having a bottom (1) and a lid (2), a in the housing between the bottom (1) and lid (2) clamped membrane (3), one of the lid (2) and the membrane (3) surrounded working space, which is connectable to a positive or negative pressure source, arranged in the working space return spring (6), which acts on the membrane (3), a protruding from the bottom (1) rod (7), which is movable in its longitudinal direction and is coupled to the membrane (3), so that the rod (7) is further pushed out of the housing at an enlargement of the working space and is drawn deeper into the housing at a reduction of the working space , According to the invention in the working space, a magnetic position sensor (8) which is coupled to the membrane (3), and a magnetic field sensor (9) for detecting a displacement of the position sensor (8), wherein in the working space between the return spring (6) and the magnetic field sensor (9) a magnetic shield (10) is arranged.
