Patent ID: 7982453

Claim:
A distance measuring device, said device comprising: a longitudinally extending housing shaped as a hollow circumferentially closed profile ( 1 ) with a constant cross section contour in longitudinal direction ( 10 ); a wave conductor unit ( 2 ) in the interior of the profile ( 1 ), wherein a wave conductor ( 3 ) of the wave conductor unit ( 2 ) extends in longitudinal direction ( 10 ) of the profile ( 1 ); processing electronics ( 12 ) in an interior of the profile ( 1 ); a traveler ( 11 ) moveable in longitudinal direction ( 10 ) along the outside of the profile ( 1 ) with a magnet ( 32 ) as a signal generator; and an outer contour ( 5 ) of the profile ( 1 ) shaped and positioned in a form fit and defined manner in lateral direction ( 8 ) in a circular interior contour ( 4 ) of an external element surrounding the outside contour ( 5 ) of the profile ( 1 ) by more than 180° of a circumference of the profile ( 1 ) so that the profile ( 1 ) can be rotated in this interior contour ( 4 ), wherein in said outer contour ( 5 ) of said profile ( 1 ) outside grooves ( 6 ) are located symmetrically spaced along the circumference and said outside grooves ( 7 ) are vase shaped with a cross section ( 7 a ) shaped as a circular segment extending over more than 180° in a lower positioned area of the outside groove ( 7 ) having a flat bottom ( 7 b ) and a V-shaped neck 7 (c) expanding from an opening of the lower positioned area of the outside groove ( 7 ) towards an outside.
