Piezoceramic Transducers for Sonar and High-power Ultrasonic Applications

Applications for Piezoceramic Transducers:

Piezoceramic components for electromechanical transducers


  • Level Sensors (oil & fuel)

Industrial applications

  • Level sensors
  • Ultrasonic cleaning
  • Ultrasonic welding
  • Ultrasonic material processing
  • Non-destructive material testing
  • Echo sounders & fish finders

Medical technology

  • Surgical knives
  • Lithotripters
  • Plaque removal
  • Ultrasonic scalpels
  • Ultrasonic nebulizers
  • Ultrasonic diagnostics and therapy

Security & Protection

  • Sonar technology & hydroacoustics
  • Underwater object recognition

Materials for power transducers

SONOX® P4, SONOX® P8, PZT401, PZT807

These materials withstand both high electrical driving voltages and intense mechanical (pressure) loads and are characterized by:

  • Low dielectric loss
  • Permittivity in between 900 and 1400
  • High mechanical quality factor in between 500 and 2000
  • High Curie temperature
  • High coercive field strength

Materials of this type are specifically well suited for high-performance ultrasonic applications in the range from 20 kHz to several MHz.
