ELECTROMAGNETIC ULTRASONIC TRANSFORMER Russian patent published in 2009 - IPC G01N29/24 

FIELD: physics, measuring.

SUBSTANCE: invention concerns transformers for the control of integrity of metal products by means of ultrasound, for example, for the control of pipelines. Electromagnetic ultrasonic transformer has one or set of magnets for appendix DC of a magnetic field to a controllable material and the electrical winding fed with a radiant alternating-current, for maintenance the AC of a magnetic flux in a controllable material. The transformer contains the attrition-resistant plate intended for slide along a surface of a controllable material. The attrition-resistant plate is made of an electrospending ferromagnetic material and has cuts. Thus, and a DC field, and an AC stream can get into a controllable material and to raise ultrasonic oscillations of this material.

EFFECT: increase of efficiency of ultrasonic transformer.
