Abstract
Суміщений електромагнітно-акустичний перетворювач для контролю металовиробів імпульсами високочастотних ультразвукових хвиль містить корпус, закріплені в ньому протектор, джерело постійного магнітного поля, що формує магнітне поле нормально поверхні металовиробу, плоску високочастотну котушку індуктивності, яка закріплена в неелектропровідній неферомагнітній основі і розміщена між джерелом постійного магнітного поля та протектором. Джерело постійного магнітного поля виконано у вигляді трубчастого елемента з закритим з одної сторони магнітним елементом отвором, так, що вони створюють в перерізі П-подібну конструкцію. При цьому П-подібна конструкція поляризована по магнітному полю так, щоб його внутрішня поверхня мала однаковий магнітний полюс. Внутрішній об'єм П-подібної конструкції заповнений пластинами з феромагнітного матеріалу з високою магнітною індукцією насичення, а площини пластин розташовані нормально площині високочастотної котушки індуктивності.The combined electromagnetic-acoustic transducer for control of metal products by pulses of high-frequency ultrasonic waves contains the case fixed in it a protector, a source of a constant magnetic field forming a magnetic field normally on a metal surface, a flat high-frequency inductor which is fixed between field and tread. The source of the constant magnetic field is made in the form of a tubular element with a closed on one side of the magnetic element hole, so that they create a U-shaped structure in cross section. The U-shaped structure is polarized by the magnetic field so that its inner surface has the same magnetic pole. The inner volume of the U-shaped structure is filled with plates of ferromagnetic material with high magnetic induction of saturation, and the planes of the plates are located normally in the plane of the high-frequency inductor.
