Yujie Piezoelectric Ceramic Ring Series
Yujie's premium piezoelectric ceramic rings engineered for superior ultrasonic transducer performance. Yujie's PZT ring series delivers exceptional energy conversion efficiency with consistent electromechanical coupling coefficient (Kp ≈ 0.42) and ultra-low impedance (≤20Ω). Available in frequencies from 27-44 kHz, these piezo ceramic rings are the industry standard for ultrasonic cleaning transducers and ultrasonic welding equipment.
