INSTALLATION WITH PIEZOELECTRIC ELEMENT FOR EQUIPPING A STRUCTURE AND PIEZOELECTRIC ELEMENT FOR SAME |
摘要 |
The invention concerns an installation with piezoelectric element for transmitting or receiving ultrasonic waves in a structure, the electrodes (8) of said element (7) being connected, as the case may be, to a powering circuit producing energizing electric signals designed to enable it to transmit ultrasonic signals in said structure (6), or to a circuit receiving electric signals transmitted by said element under an energizing ultrasound received by it from said structure, said piezoelectric element (7) being integrated in the structure. The powering or receiving circuits of said piezoelectric elements (7) consist each of a magnetic induction loop (9) likewise comprised in the structure (6) and capable of receiving from an external circuit (10, 11) or respectively transmitting thereto, electromagnetic signals.
