ULTRASOUND FAULT DETECTOR, ULTRASOUND CONVERTER AND ULTRASOUND FAULT DETECTION TECHNIQUE Russian patent published in 2015 - IPC G01N29/24 

FIELD: electricity.

SUBSTANCE: main housing of the converter has an oscillating plate at the exposed face; the plate is curved at the side-view and the matched surface with a larger diameter formed at the bend of layered part. At the oscillating plate in the converter main housing shaped as a matrix in direction of the bend and width there is a variety of placed piezoelectric generators. In each group of the generators the control unit switches the piezoelectric generators to transmitting and receiving piezoelectric generators in turn, in the direction of width, as per the earlier set model of transmission/transfer and processes the signal received from the piezoelectric generator according to aperture synthesis method.

EFFECT: potential implementation of high signal-to-noise ratio and increasing accuracy of fault detection.
