Basic Info

    Model No.: 70 x 10 x7.8mm PZT-41

Product Description

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.

Low frequency piezoelectric hydrophone components

Features :

  • Trapezidal strip, angel on request
  • Sizes from 1mm up to 200mm
  • Thickness from 0.2mm up to 25mm
  • piezo material HARD PZT PZT-4 series

Piezoelectric ceramic Material: PZT-41

Hard PZT

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.

PZT-4 series

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.
