ACOUSTICAL-ELECTROMAGNET TRANSDUCER Russian patent published in 2005 - IPC

FIELD: nondestructive testing.

SUBSTANCE: device can be used for measuring thickness of items made of aluminum and steel. Acoustical-electromagnet transducer intended for the acoustical device for ultrasonic testing of different materials has biasing system and probing pulse oscillator. Oscillator has active element, capacitor and inductance coil. Winding of inductance coil is made of at least two independent departments having like direction of reel. Device is additionally provided with active elements and capacitors, which form independent oscillators with any department of winding. Active elements, for example, transistors are made for connecting synchronously or with phase shift.

EFFECT: improved precision of measurement; reduced consumed power; widened operational capabilities.
