A measuring location sensor for use with linear measurement devices intended for measuring or checking the position of a pre-determined measuring location on an object, e.g. the chassis of a motor vehicle. The measuring location consists of a hole (24) located in the object or the head (27) of a screw, or the like. The sensor includes a probe (26) which can be displaced linearly in a pre-determined direction and which is dimensioned to abut the defining edge of the hole or the defining edge of the opening (28a) at one end of an open-ended sleeve (28), the length of which is known and the other end of which is inserted over the protruding element. The probe tip (26) of the probe has the form of a sphere of pre-determined, known radius (R), such as to achieve precise and anambiguous abutment with the defining edge of the hole (24) or the sleeve-opening (28a), irrespective of whether the hole or the protruding element is located on a horizontal surface or an inclined surface of the object. |
