Abstract

The invention relates to a measuring arrangement comprising a receiving component (1) with a conical recess (2) and a measuring bolt (3) with a conical outer circumferential surface (4) formed at least partially corresponding to it, wherein the measuring bolt (3) is arranged at least partially in the conical recess (2), has at least one sensor (5) at an end directed into the conical recess (2) and has clamping means (6) at an end directed out of the conical recess (2) for generating a preload between the conical recess (2) and the conical outer circumferential surface (4).According to the invention, the measuring bolt (3) is first inserted axially, at least partially, into the conical recess (2), and then the clamping device (6) is screwed onto the end of the measuring bolt (3) extending out of the conical recess (2) to generate a preload between the conical recess (2) and the conical outer circumferential surface (4) of the measuring bolt (3), and the sensor (5) is used at the end of the measuring bolt (3) extending into the conical recess (2) to monitor whether the required preload has been achieved.
