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 than 180°, so that it still can be rotated inside the interior contour.
