Verfahren und Vorrichtung zur Messung des Abstandes bzw. der Bewegung zwischen zwei durch eine Dichtung getrennten Maschinenteilen

摘要

The proposed method of measuring the distance or movement between two machine parts separated by a seal involves embedding at least one capacitive and/or inductive impedance element in the (at least in part non-metallic) seal in such a way that a change in the distance between the machine parts results in a change in the impedance of the impedance element(s) which is then measured and taken as an indicator of the distance or movement.
