ABSTRACT:
A device for monitoring the tolerances of a workpiece has a measuring probe with two separate inductive coils arranged in a housing. A non-magnetizable sensing stylus designed to rest on a workpiece surface to be measured is arranged in the coils and has a deflector body that is a sleeve. The stylus and the deflector body are loaded into a measuring position. The housing has two essentially identical housing halves each having a plane surface with which the housing halves are connected to one another. The housing halves each have a recess and one of the inductive coils is inserted into one of the recesses, respectively. The opposed ends of the housing halves are provided with aligned bores that open into the recesses, respectively. The stylus is arranged coaxially in the inductive coils and has opposed stylus ends projecting through the bores outwardly from the two housing halves.
