ELECTROMAGNET-ACOUSTIC TRANSDUCER Russian patent published in 2008 - IPC G01N29/24 

FIELD: physics.

SUBSTANCE: invention is related to the field of nondestructive control, namely to devices of determination of textural anisotropy, thickness and deflected mode of structures and rolled metal, such as tapes, strips, tubes, etc. Electromagnet-acoustic transducer contains magnet system with two coplanar dissimilar poles and flat coil of rectangular shape installed in plane parallel to poles at minimum distance from them, at that within limits of coil turns extended part area there are projections of poles onto coil plane. Additionally in transducer second flat coil of rectangular shape is introduced, which is also installed in plane that is parallel to poles at minimum distance from them and the first coil, at that part of the second coil extended coils area is installed within limits of projection of one of magnet system poles onto coil plane, the other part of the second coil turns area stays in space between projections of poles onto plane of the second coil, and turns of the first and second coils within limits of their extended part area are mutually perpendicular.

EFFECT: expansion of transducer functional resources.
