    • The invention relates to a method for non-distructive testing of a drive shaft (110), which is accessible from one end thereof, by means of an annular ultrasonic multi-element longitudinal wave transducer (900;1000) comprising independent elements excitable by equifrequent electric pulses for which the inventive method consists in applying different electronic phase shiftings to the pulses transmitted thereto. Said electronic phase shifting makes it possible to focus or deviate a final beam which is synthesised by the totality of elements forming the transducer and to concentrate said final beam in such a way that a generally cylindrical cross-section thereof substantially smaller than the testable shaft cross-section is adopted and is highly energetic at a long distance by a wave guide action produced by the cylindrical shape of the shaft.

    • PURPOSE: A sensor system and a transducer-based sensor are provided to improve processing speed and performance of the sensor system, and to prevent cross-transducer interference by receiving phase-shifted variant signals of local oscillators in the transducers. CONSTITUTION: A sensor system(10) is composed of plural transducer groups(12), and the transducer group is composed of plural transducers(12a,12b,12c,12d) operated and arranged near samples(14). The transducers activate by receiving phase-shifted variant signals(30a,30b,30c,30d) of local oscillators. The sensor system prevents cross-transducer interference between the activated transducers by selectively using the phase-shifted variant signals of the local oscillators during output processing. An oscillator sub system(16) generates the phase-shifted variant signals to the transducers of the transducer groups.
