Power transducers demand materials that perform reliably under extreme conditions - high electrical drive voltages, intense mechanical stress, and continuous operation. CeramTec's piezoceramic materials for power transducer applications have been engineered to meet exactly these requirements.
Whether used in industrial ultrasonic systems, sonar technology, or medical devices, our SONOX® materials deliver outstanding electromechanical efficiency, long-term stability, and precise frequency control - even at high power levels and across a wide frequency range from 20 kHz to several MHz.
What are Typical Applications for Piezoceramic Power Transducers
| Market | Application |
|---|---|
| Automotive | Level sensors (oil & fuel) |
| Industrial | Ultrasonic cleaning, ultrasonic welding, ultrasonic material processing, non-destructive testing (NDT), level sensors, echo sounders & fish finders |
| Medical Technology | Ultrasonic diagnostics & therapy, ultrasonic scalpels & nebulizers, lithotripters, surgical knives, plaque removal |
| Security & Defence | Sonar technology & hydroacoustics, underwater object recognition |
