Abstract
The invention concerns a probe head of the so-called measuring type with scales which supply signals proportional to the position of a probe pin in its deflected state. A probe-pin carrier is the movable part of the probe head, being mounted indirectly on at least three intermediate bodies which, in their turn, are guided linearly in a fixed or housing part of the probe head. As a result of the symmetrical arrangement of the linear guides and the identical mass of intermediate bodies, like inertial responses characterize probe deflection in all directions in space. The workpiece-contacting force is, therefore, independent of coordinate direction in a dynamic operation of the probe head, as in the course of a continuous scan of a workpiece profile.
