Actuating device for producing linear movement, has contraction element extended between end pieces, where Hall sensor is arranged in interior of element for detecting rotation of magnet occurred during contraction of element

摘要

The device (1) has a hollow, elastically bending contraction element (4) extended between end pieces (2, 3), where interior (7) of the contraction element is pressurized with a fluidic pressure medium. A measuring arrangement and a spring-loaded rope are arranged in the interior. The rope is looped around a cylindrical permanent magnet (13). Arrangement of the magnet and the rope is fixed in an area of the pieces. A Hall sensor (18) is arranged in the interior for detecting rotation of the magnet occurred during contraction of the contraction element. The device is formed as a fluidic muscle.
