ULTRASONIC TRANSDUCERS

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.
