Product Description

Parameters

Piezoelectric ceramic sphere

Electrode direction: Rarial direction

Yuhai company developped piezo sphere elements of various hemisphere and focal bowl sizes, this range is fabricated from more than 10 available piezoelectric material formulations according to high sensitive, temperatures etc applications.

Applications includes:

underwater acoustic sensors
Hydrophones

Features :

Sizes from 6mm up to 160mm
Thickness from 1mm up to 10mm
Choice of metallisation (Silver, Nickel, Gold and others on request)
Wide choice of PZT formulations

Piezoelectric Ceramic Material: PZT-43(equal to PZT-4d)

PZT-43 is suitable for both constant and repetitive conditions in sonar, ultrasonic cleaning, and other high power applications. This material produces large mechanical drive amplitudes while maintaining low mechanical and dielectric losses. Applications include STM, nano-positioning, and medical therapeutics.
