    摘要： A precision sensor assembly for rotating members in a machine tool comprises a rotor unit (16) rigidly fixed to a rotor portion (2a) of the machine tool and including a sensor (5) for detecting vibrations produced by the operation of the machine tool, the sensor (5) comprising a piezoelectric sensitive element (6) and members (7, 8) for mechanical amplification of the vibrations. The members (7, 8) comprise at least one resonant system composed of an elastic element (8) and a counter-mass (7) acting on the piezoelectric sensitive element (6). The rotor and stator units (16, 17) comprise inductively coupled transmitting and receiving elements (10, 11) for transferring the signals from the piezoelectric element (6) contactless to the stator unit (17). The stator unit (17) may include an electric amplifier (13) for further amplifying the transmitted signals.
