Langevin transducer. Almost all piezoelectric transducers for power ultrasonics are of the Langevin type — i.e., one or more piezoceramics that are mechanically compressed (prestressed) between a front driver and a back driver. The piezoceramics are typically constructed to operate in one of two modes — 33 or 31. See details. 33 mod Piezo-Electric Transducer.
