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

A magnetostrictive position or elongation sensor of the type in which an elongated magnetorestrictive waveguide is influenced by a magnetic field from a moving magnet has a Villary type transformer at one end and a hermetically sealed housing containing the signal processing circuitry on a plurality of circuit boards. The signal processor can switch the sensor into a programmable mode in which a diagnostic output is obtained recognizing the magnet, the presence of the sensor in the programming mode and voltage values.

A system and method for measuring the absolute position of one body which is constrained to move with respect to another body includes a plurality of magnetic identification units, which are adapted to be mounted in a predetermined absolute position on a first body. Each of the magnetic identification units has an identity characteristic that is associated therewith. A Sensor having a transducer is adapted to be fixed to a second body. The transducer is adapted to sense (a) the relative distance of at least one of the magnetic identification units with respect to a benchmark location which is fixed relative to the transducer and the second body. It is also equipped to sense the identity characteristic of the sensed unit. A controller is provided to receive data representing the relative distance and identity characteristic of the sensed unit from the sensor. The controller identifies the sensed unit from the identity characteristic, recalls the predetermined absolute position of the sensed unit and determines an absolute position for the benchmark location by summing the predetermined absolute position of the sensed unit with the relative distance of the sensed unit to the benchmark position.
