An ultrasonic converter is a device that transforms electrical energy into ultrasonic waves (high-frequency sound waves beyond the range of human hearing) or converts ultrasonic waves back into electrical energy, typically using the piezoelectric effect. It is commonly used in applications like ultrasonic cleaning, welding, medical imaging, and sensing.

An ultrasonic converter is used in industrial cleaning, welding, and non-destructive testing, as well as medical imaging like ultrasounds and therapeutic procedures. It powers sensors in consumer electronics and supports research in sonochemistry and material analysis. Its precision and efficiency make it essential across industrial, medical, and scientific applications.

An ultrasonic converter works using the piezoelectric effect, where piezoelectric materials convert electrical energy into high-frequency ultrasonic waves or vice versa. When an alternating electrical signal is applied, the material vibrates at ultrasonic frequencies, producing sound waves for applications like cleaning, imaging, or sensing. It reverses this process for detection.

The main components of an ultrasonic converter are the piezoelectric element for generating ultrasonic waves, backing material to absorb excess vibrations, housing for protection, a connector to interface with power or signals, and sometimes a front mass to improve wave transmission, ensuring efficient conversion of energy into ultrasonic vibrations.

To maintain an ultrasonic converter, regularly clean it to prevent debris buildup, ensure proper cooling during operation to avoid overheating, avoid exceeding the recommended power and frequency ranges, store it in a dry, temperature-controlled environment, and inspect for damage or wear, particularly in the piezoelectric element and housing.
