Product Description

Parameters

Piezoelectric ceramic hemisphere Electrode direction: Radial directionCustom piezo sphere

Hard PZTHigh power or "hard" PZT ceramics can withstand high levels of electrical excitation and mechanical stress. These materials are suited for high voltage or high power generators and transducers.Pzt-4 SeriesThis material range is ideally suited for ultrasonic cleaning, sonar, and other high power acoustic radiation applications. These materials are designated as PZT-4 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. Yuhai company offer a complete range of three PZT-4 series material types with a variety of permittivity values, coupling, power handling and actuation properties.

Applications: underwater acoustics hydrophone

Material: PZT-43(equal to Pzt-4D)
