Abstract (en)

The device has a cylinder tube (1) closed by a base (4) and top (3) with a piston subjected to pressurized medium on at least one side, a piston rod (2) and at least one sensor (8a,b) for detecting the piston rod position movable mounted on the cylinder tube. At least one axis-parallel closed channel (7) is provided for mounting the sensor in the wall region of the non-magnetic cylinder tube in a sealed manner.

Abstract (de)

Um bei einem Druckmittelzylinder zur Erzeugung einer mechanischen Kraft, mit einem von einem Zylinderboden (4) sowie einem Zylinderdeckel (3) endseitig verschlossenen Zylinderrohr (1), in dem ein mit Druckmittel zumindest einseitig beaufschlagbarer Kolben längs verschiebbar angeordnet ist, von welchem eine den Zylinderdeckel (3) abgedichtet durchdringende Kolbenstange ausgeht, wobei zur Detektion der Kolbenstcllung mindestens ein Sensor (8) längs verschiebbar am Zylinderrohr (1) montiert ist, diesen zuverlässig gegen äußere Einflüsse geschützt am Zylinderrohr auf einfache Weise montierbar/demontierbar bzw. justierbar anzuordnen, wird vorgeschlagen, dass zur abgedichteten Unterbringung des Sensors (8) im Wandungsbereich des nichtmagnetischen Zylinderrohrs (1) mindestens ein achsparallcler geschlossener Kanal (7) vorgesehen ist, in dem der Sensor (8) über magnetisch betätigbare kraft- oder formschlüssige Befestigungsmittel arretiert ist. <IMAGE>
