Abstract: A distance measuring device, in particular a magnetostrictive distance measuring device wherein a distance measuring element extends in longitudinal direction of the device along the measurable measuring distance, relative to which a signal generating signal generator can be moved in longitudinal direction, with a longitudinal housing shaped as a circumferentially enclosed profile (1) with constant cross section contour in longitudinal direction (10), a wave conductor unit in the interior of the profile (1), wherein the wave conductor of the wave conductor unit extends in longitudinal direction (10) of the profile (1), processing electronics in the interior of the profile (1), a traveler moveable in longitudinal direction (10) along the outside of the profile (1), in particular with a magnet as signal generator, wherein the profile (1) is shaped so that it can be positioned in lateral direction in a form fit manner, within a circular interior contour surrounding the outside contour of the profile (1) by more

Abstract: For easy production of an alternately magnetisable measuring scale there is proposed for example a C-shaped magnetisation head 52 in which the magnetic flux through its air gap in which the measuring scale is disposed can be definedly switched on and off.

Abstract: A measuring cable travel sensor includes a housing accommodating a measuring cable drum and a rotary spring urging the cable drum in the direction of winding of a measuring cable thereon. At least one braking magnet is arranged either on the cable drum or on the housing to provide for magnetic control of the rotary movement of the cable drum at least in the cable winding-on direction. The cable drum may also carry holding magnets for holding the winding cable into close contact with the peripheral surface of the cable drum. The housing may also have a band extending at least in part around the cable drum for correctly positioning the cable thereon as it is being wound on.
