<p>The device has a scanning unit (10) attached to a housing (11). A coupling rod (22) is connected with a measuring rod (20) that is moved within the housing to a longitudinal guidance (12) in a measuring direction (X). A tube (24) is extended longitudinally in the direction and is connected with the measuring rod, such that the tube is guided parallel in the direction by the guidance via an opening (25) of the housing. The coupling rod runs within the tube, where the tube enables balance movements, of the coupling rod within the tube, running transverse to the direction.</p> |
