Abstract
A measuring cable travel sensor includes a housing and a cable drum which is arranged in the housing rotatably and longitudinally displaceably in the longitudinal direction of the travel sensor. The measuring cable is guided into and out of the housing through a stationary cable guide. The travel sensor has a longitudinal drive for displacing the cable drum, including a spindle drive comprising a screwthreaded spindle and a spindle nut screwable thereon. The longitudinal drive has an additional transmission for transmitting rotary movement of the cable drum to the spindle drive for producing cable drum displacement.

A measuring cable travel sensor, comprising:
- a housing,
- a cable drum,
- means mounting the cable drum in the housing rotatably and longitudinally displaceably in the longitudinal direction relative to the axis of drum rotation,
- a measuring cable adapted to be wound on to and unwound from the cable drum,
- a cable guide means for the measuring cable, arranged stationarily with respect to the housing,
- a longitudinal drive means for the cable drum including a spindle drive means comprising a screwthreaded spindle and a spindle nut screwable thereon,
- the longitudinal drive means including an additional transmission means for transmitting the rotational movement of the cable drum to the spindle drive means.
A measuring cable travel sensor, comprising:
- a housing,
- a cable drum,
- a retaining mount which rotatably fixes the cable drum in the housing and longitudinally displaces the cable drum in the longitudinal direction relative to the axis of drum rotation,
- a measuring cable adapted to be wound on to and unwound from the cable drum,
- a cable guide arranged stationarily with respect to the housing, and
- a longitudinal drive for the cable drum including a spindle drive comprising a screwthreaded spindle and a spindle nut screwable thereon,
- the longitudinal driver including an additional rotational movement unit for transmitting the rotational movement of the cable drum to the spindle drive.
