Abstract:
1. A positioning device ( 100 ) for a rod-shaped measuring device ( 200 ) for determining a measured quantity at a measuring point (M) of an object ( 300 ), with a cylindrical guide element ( 110 ), in which the measuring device ( 200 ) is guided in such a way that it contacts the measuring point (M), and with a spring element ( 120 ), which is mounted between a first stop ( 210 ) that is connected with the measuring device ( 200 ) and a second stop ( 132 ), for pressing the measuring device against the measuring point (M), wherein a sleeve ( 130 ) is provided, which is connected in axial extension to the terminal end of the cylindrical guide element ( 110 ) with respect to the object and in which the spring element ( 120 ) and the measuring device ( 200 ) are guided, wherein the second stop ( 132 ) is designed as a disk-shaped aperture plate ( 132 ′) with a central aperture ( 133 ), through which the rod-shaped device ( 200 ) is passed, and where the second stop ( 132 , 132 ′) for the spring element ( 120 ) is axially displaceable, together with the sleeve ( 130 ), beyond the terminal end of the cylindrical guide element ( 110 ) with respect to the object, and is adjustable to and fixable in place in any desired position on the sleeve.
