Abstract
The invention pertains to a probe for sensing the characteristics of a surface of a workpiece which contains a probe tip that is movably held and prestressed essentially in the direction of the tip (Z-direction) and mounted without play to a first acceleration transducer. The first acceleration transducer transforms the movements of the probe tip and consequently the measurement data into acceleration data, with the first acceleration transducer being movably held and prestressed in the direction of the tip (Z-direction) and fixedly connected to the probe tip. A first integrator performs double integration with respect to time of the acceleration data from the first acceleration transducer, thereby forming longitudinal measurement data which correspond to the features of the sensed surface. The probe is thus able to sense the shape as well as the undulations, or roughness of the surface of a workpiece and outputs the features in the form of a corresponding measurement voltage.
