Our ultrasonic transducers consist of a piezoelectric ceramic
element, mounted in
an aluminum, plastic, or environmental (sealed) housing. These
transducers 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.
