35×15×5mm PZT-8 Ring Piezoelectric Ceramic, 42kHz Low-Frequency High-Power Piezo Ring

Industry Background

Large-size low-frequency ring piezoelectric ceramics are key core components for high-power ultrasonic equipment such as ultrasonic cleaning machines, ultrasonic welding transducers and large-range distance measuring devices. As industrial ultrasonic equipment continues to move towards higher power output and larger processing scale, the demand for piezo ceramic rings with large diameter, low resonant frequency, low impedance and stable performance keeps rising. Low-quality rings often suffer from high heat generation, parameter drift and short service life under high-power continuous operation. As a professional piezo ceramic manufacturer, Guangdong SWT supplies various large-size ring piezo ceramics with reliable batch quality for global industrial ultrasonic customers.
