  • Probe element for coordinate measurement systems
    Patent number: 5524354
    Abstract: In a probe element for coordinate measuring systems using micro-probe elements and piezo-resonators which change their resonance characteristics upon contact, the probe element has piezo-resonators arranged in a polygonal configuration. Micro-probe elements are arranged in a polygonal configuration on the piezo-resonators and sense inner and outer surfaces in different coordinates. The tactile sensing of the micro-probe elements on the surface of the specimen is effected by measuring the change in the resonance characteristics of the piezo-resonators.
