Abstract

The invention relates to the means of the indestructible control of the articles.The substance of the invention is the raise of the sensitivity by increasing the energy concentration of the received oscillations. The completion of the supersonic mode transducer as align and contact setted a piezoelectric element 1 in the form of a disk, a steel plate 4 and a piezoelectric element 2 in the form of a short bar, the diameter of which is smaller than then the diameter of the piezoelectric element 1, ensures the conversion of the received supersonic oscillations by their propagation from the piezoelectric element 1 into the piezoelectric element 2. Owing to this the amplitude of the electric signals taken away from the piezoelectric elements 2 surface is increasing.
