Piezoceramic Ring Application:

The piezoelectric components are fastened to the metal rod with bolts, which enable the particle displacement or velocity of the mechanical vibration of the piezoelectric components to be amplified, and the ultrasonic energy is concentrated on the smaller area, that is, the ultrasonic concentrator. We can provide a variety of ring-shaped components with low resonant impedance, low dielectric loss, good thermal stability, and high-power drive.

Piezo ceramics are used in Bolt-clamped ultrasonic transducer, Ultrasonic Sensor, Vibration Sensor, Vibration generation, Biodiesel mixing transducer, ultrasonic cleaning, ultrasonic welding, and active vibration damping.
