Product Description

Parameters

Piezoelectric ceramic tubes

Electrode direction: Radial direction

Yuhai company developped ultrasonic tube elements and custom tube sizes, this range is fabricated from more than 10 available piezoelectric material formulations according to high sensitive, temperatures etc applications.

Applications includes:

NDT Non destructive Testing
underwater acoustics
hydrophone

Features :

Sizes from 1mm up to 100mm
Thickness from 0.5mm up to 15mm
Choice of metallisation (Silver, Nickel, Gold and others on request)
