Abstract

Abstract Recently in Romania the use of high power ultrasonics in electrically conductive solid media has increased. Consequently more severe conditions have been imposed on inductive transducers regarding their sensitivity and selectivity for measuring acoustic field amplitudes. In view of this the authors carried out theoretical and experimental studies on inductive transducers. Parameters that influence the back emf in an idealized physical model, can be particularized for every practical case. By reducing the magnetic reluctance of the air closed field lines, transducers with a sensitivity of about 400 mV/μm have been built. These transducers may possibly be used at higher frequencies. Also, selective transducers for longitudinal and transverse vibrations were made by altering the geometry and position of their constituent elements.
