ABSTRACT:
A contact sensing probe having a stylus which is vibrated longitudinally by a piezoelectric transducer. Contact with a workpiece is detected from damping of the vibration. The stylus is mounted to a probe body via parallel diaphragm springs. These cooperate with a counter mass to form a mechanical low pass filter, which isolates the stylus vibrations from influences caused by the mounting or handling of the probe body.
