Abstract
A system for damping the reflection wave at the open end (6) of a magnetostrictive sensor system has at least one magnet device (2) movable relative to a measuring wire (1) that can be deflected mechanically and that experiences a deflection under the influence of a current pulse (3). The deflection can then be processed by a signal device (5). The system has at least one damping part (8) lying against the measuring wire (1) by a sleeve-shaped enclosure (11). The sleeve-shaped enclosure (11) can be deformed from an expanded initial state intended for attaching the sleeve-shaped enclosure to the damping element (9), to a constricted functional state that exerts a clamping force on the damping element (9). The method is characterized in that the sleeve-shaped enclosure (11) is constricted to an increasing extend from the end (19) of the sleeve-shaped enclosure adjacent to the signal device (5) to the other end (19′) so that the tubular damping element (9) is likewise pressed into a conical contour. At least the conical contour of the sleeve-shaped enclosure (11) is continuous and without interruption.
