Einsatzgebiete ergeben sich insbesondere in der Automobilindustrie, beispielsweise zur Bestimmung der Lage beziehungsweise Höhe bei Fahrwerksystemen oder bei Headlight-Leveling-Systemen (Leuchtweitenregulierung) und auch innerhalb beziehungsweise außerhalb eines konventionellen Dämpfers (Ein- oder Mehrrohr) oder an schaltbaren Dämpfern, wie diese bei Luftfedern und Luftfederdämpfern benutzt werden.Such measuring devices are used for example to determine the position of a piston in a cylinder. Areas of application arise in particular in the Automotive industry, for example, to determine the position or Height at Suspension systems or headlight leveling systems (headlamp leveling) and also inside or outside a conventional one damper (Single or multi-pipe) or on switchable dampers, as with air springs and air spring dampers to be used.

aus der
Der Nachteil dieser bekannten Messeinrichtung besteht darin, dass der hierbei verwendete Informationsträger je nach Ausführungsform unterschiedliche Nachteile aufweist. Wird der Informationsträger nach Art eines Tonbands hergestellt, ist die Herstellung zwar einfach, jedoch das Ergebnis nicht robust. Ein beschädigter Informationsträger kann keine vernünftigen Daten mehr liefern. Macht man den Informationsträger robuster, beispielsweise durch eine mechanische Bearbeitung der Kolbenstange, bei der Lücken gefräst werden, die dann mit einem Material mit anderen magnetischen Eigenschaften als das Grundmaterial ausgegossen werden, so schlägt sich dies in den Herstellungskosten nieder. Weiterhin lässt sich dadurch nur eine geringe Auflösung erzielen.The disadvantage of this known measuring device is that the information carrier used here depending on embodiment has different disadvantages. If the information carrier after Type of tape, the production is simple, However, the result is not robust. A damaged information carrier can not reasonable Deliver more data. Make the information carrier more robust, for example mechanical machining of the piston rod, in which gaps are milled, then with a material with different magnetic properties As the base material is poured out, so does this in the manufacturing costs down. Furthermore, this can only a small resolution achieve.
