Ultrasonic Annunciator

Using piezoelectric ceramics, this device generates ultrasound (20 kHz and above) through high-frequency mechanical vibrations driven by AC voltage. It enables non-contact, high penetration sensing and energy transmission. Ideal for industrial flaw detection, precision cleaning, flow measurement, and robotic sensors, it performs well in complex environments.
