Design of Ultrasonic Resonant Air-Borne Tracking System

Impedance spectroscopy is the study of measurement of impedance and phase with respect to frequency of electrical components or material under study. In the present work, an electrical impedance analysis of air-borne ultrasonic transducers is carried out with the help of a dedicated impedance analyzer, AD5933, manufactured by analog devices. It is a sweep type of resonant frequency tracking instrument that helps to detect the exact resonant frequency for ST 40 and SR 40 transmitter and receiver air borne transducers, respective. It is observed that impedance analyser, AD5933 is effective in the resonant tracking of air borne ultrasonic transducer.
