METHOD FOR AUTOMATICALLY REGULATING OPERATION OF ULTRASOUND TECHNOLOGICAL DEVICE AND ULTRASOUND TECHNOLOGICAL DEVICE FOR REALIZATION OF THE METHOD

摘要

FIELD: technological equipment for ultrasound processing of various purposes.;SUBSTANCE: in the method for auto-adjusting operation of ultrasound technological device, containing more than one electro-acoustic transformer, on basis of differential check connection signal, electro-acoustic transformers are excited in such a way that mechanical oscillations of one group of transformers are performed in on direction, and of remaining transformers - in anti-phase, while check connection signal is formed a difference of signals proportional to full currents through these groups of transformers. Device for realization of the method contains ultrasound generator, electro-acoustic transformers, connected to output of generator, and circuit for check connection with bridge circuit, both shoulders of which have coupled electro-acoustic transformers and balancing resistances.;EFFECT: reduced error of check connection signal, and as a result, increased precision of adjustment.;2 cl, 1 dwg
