NiCera ultrasonic transducers
use piezo ceramic elements capable of transmitting and receiving airborne
ultrasonic ‘noise’. When driven from an alternating voltage
source of suitable frequency, the piezo ceramic element distorts in
proportion to the applied voltage, generating sound waves. Conversely,
when the element is exposed to an ultrasonic wave a voltage proportional
to its intensity will be generated.
NiCera’s extensive range of ultrasonic transducers is suitable for volumetric security applications in cars or in the home and includes designs specifically for automotive reversing and proximity alarms. There’s a choice of frequencies and diameters.
