Functional description
The linear movement of a flexible steel cable, which can have a length of up to 10.4 m, is converted
into a rotary movement with the aid of a measuring drum. The measuring drum is connected to the
shaft of an encoder. In this way a change in displacement of the measuring cable causes the shaft
of the encoder to rotate by a directly proportional amount which can be recorded.
The restoring force of the spring drive holds the measuring cable tight at all times and prevents any
sagging which would otherwise induce an error. The measuring drum moves axially on a spindle
ensuring that the cable is wound up precisely and reproducibly wrap for wrap in the helical groove
of the drum.
