Ultrasonic transducers using radial vibrations of a piezoelectric disk
Suggestions concerning the use of radial vibrations of a piezoelectric disk in ultrasonic transducers working in the frequency range below 100 kHz are presented. Experimental data from investigations of two types of trans-ducers are given, one using axial coupling of a piezoelectric disk with a metal rod vibrating in the longitudinal mode, the other using circumferential coupling of a piezoelectric disk and a metal plate. The amplitude and phase characteri¬stics of admittance, the resonance curves, the temperature characteristics of impedance and the resonance displacement amplitudes are presented.
