Device having a supply line with a sensor line for torsion measurement and the method thereof

Abstract

The invention relates to a device (). Said device has two machine parts () that are movable relative to one another and are connected to each other by a supply line () along which a sensor line () is mounted for measuring torsion of the supply line (); the sensor line () is connected to a measurement unit () which is designed in such a way that an electrical parameter (P) of the sensor line () is measured, the torsion being ascertained using said parameter (P). The invention further relates to a corresponding supply line (), a sensor line () and a torsion measurement method.
