What Is an Ultrasonic Transmitter?
An ultrasonic transmitter is a device that generates ultrasonic waves, high-frequency sound waves, to transmit information.
There are several types, including piezoelectric and magnetostrictive. Piezoelectric transmitters use piezoelectric elements to generate ultrasonic waves, offering high output and directionality but potentially limited frequency characteristics. Magnetostrictive transmitters, however, utilize magnetostrictive materials to generate waves. While their output may be lower than that of piezoelectric types, they provide better frequency characteristics.
Ultrasonic transmitters are employed in various applications such as non-destructive testing, distance, level, and speed measurement, medical diagnostic devices, and ultrasonic cleaning. They are known for their non-contact measurement capability, high precision, and directionality, with ongoing advancements in miniaturization and energy efficiency.
