Abstract (en)
[origin: DE19547313A1] 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.
