Piezoelectric sphere 4MHZ-HIFU
Piezoelectric ceramic Hemisphere
Electrode direction: thickness vibration
YUHAI company developed various piezo hemisphere and focal bowl sizes for HIFU transducer, sonar transducer, hydrophone etc, this element is fabricated from more than 10 available piezoelectric material formulations according to high power, sensitivity, stability needs in cryogenic temperatures as also in high temperatures and extreme pressure applications.
· Sonar transducers
· HIFU medical and industrial
· Underwater communications
· Choice of metallisation (Silver, Nickel, Gold and others on request)
· Evaporated and chemically deposited metallisation's available
· Thickness frequency tuning available on request
· Wide choice of PZT formulations
Piezoelectric Ceramic Material: PZT-82 (equal to PZT-8)
P-82 Is equal to PZT-8, hard PZT for higher mechanical quality factor, lower dielectric loss required and much higher power handling capability etc. transducers.
