Piezoelectric ceramic Trapezoid strips for low frequency hydrophones
Yuhai's piezoelectric block has been utilized continuously in low frequency hydrophones in more than 30 years.
A hydrophone is a microphone designed to be used under water for recording or listening to underwater sound. Most hydrophones are based on a piezoelectric transducers that generates an electric potential when subjected to a pressure change, such as a sound wave.
Piezoelectric ceramic Material: PZT-41
High power or "hard" ceramics can withstand high levels of electrical excitation and mechanical stress. These materials are suited for high voltage or high power generators and transducers.
This material range is ideally suited for ultrasonic cleaning, sonar, and other high power acoustic radiation applications. These materials are designated as PZT400 series type materials and are capable of producing large mechanical drive amplitudes while maintaining low mechanical and dielectric losses. In addition, it can be used under both constant and repetitive conditions. Within this group of materials, CeramTec offer a complete range of three PZT400 series material types with a variety of permittivity values, coupling, power handling and actuation properties.
