Displacement sensor for measuring cable for determining precise position of object: has casing provided by extruded profile enclosing rotation angle sensor, reverse rotation spring and cable drum for measuring cable

摘要

The sensor has a casing enclosing a cable drum for a measuring cable attached to a measured object, a rotation angle sensor (6) and a spring (5) for reverse rotation of the cable drum, positioned coaxially. The casing is provided by a linear profile with a uniform extruded profile cross-section in the longitudinal direction. At least one leg of the profile has longitudinal grooves.
