Abstract
A probe head for a coordinate-measuring instrument has a torsionally rigid, play-free and friction-free probe-suspension system which defines a three-dimensional coordinate system wherein the work-contact pin of the probe is deflectable in all three directions in space. For each of the three coordinate directions, an incrementally operating displacement-measuring system is provided, and each such system is associated with a zero indicator for recognition of the zero position of the system. Upon initial contact of the probe with the object to be measured, a trigger pulse is produced via a sensor. A subsequent electronic system processes the different signals delivered by the probe head so that optional operation is available either as a switching probe head or as a measuring probe head.
