Abstract:
1. A device for monitoring the dimensional, shape, and positional tolerances of a mechanical workpiece, the device comprising: at least one measuring probe comprising a housing attachable to a support; first and second separate inductive coils arranged in the housing and having identical size; a sensing stylus adapted to rest on a surface to be measured of a workpiece; and a deflector body arranged on the sensing stylus; wherein the sensing stylus is a piston comprised of a non-magnetizable material; wherein the deflector body is a sleeve; wherein the sensing stylus and the deflector body are movable by a force into a measuring position; wherein the housing is comprised of a first shell-shaped housing half and a second shell-shaped housing half, wherein the first and second housing halves are at least mostly identically designed and each have a plane surface, wherein the first and second housing halves are connected to one another at the plane surfaces; wherein the first and second housing halves each have a recess beginning at the plane surface, respectively; wherein the first inductive coil has first connecting lines and is inserted together with the first connecting lines into the recess of the first housing half; wherein the second inductive coil has second connecting lines and is inserted with the second connecting lines into the recess of the second housing half so as to be aligned with one another; wherein the first and second housing halves have opposed ends, wherein the opposed ends have a bore opening into the recess, respectively, and the bores are aligned with one another; wherein the sensing stylus is arranged coaxially in the first and second inductive coils and has opposed stylus ends projecting through the bores outwardly from the two housing halves.
