Our air transducers consist of a piezoelectric ceramic element, mounted in an aluminum, plastic, or environmental (sealed) housing. These piezoelectric transducers (PZT) offer high sensitivity, superb sound pressure level (SPL), and stable electrical and mechanical characteristics, at a choice of bandwidths. Environmental transducers may act as both transmitter and receiver; or separate transmitter or receiver.
