Product Description
Parameters

Piezoelectric ceramic disc Quick deliverywrapped arround electrode availableYuhai company developped piezo disc elements of various sizes, this range is fabricated from more than 10 available piezoelectric material formulations according to high sensitive, temperatures etc applications. Applications includes: high driving piezo transducer

Features : Sizes from 3mm up to 200mm

Thickness from 1mm up to 10mm

Choice of metallisation (Silver, Nickel, Gold and others on request)

Wide choice of PZT formulations

Application: high power ultrasonic vibration transducerMaterial: PZT-82 (hard PZT, equal to PZT-8) P-82 is used in high power applications and has an extremely high mechanical quality. With the ability to withstand high levels of electrical excitation and mechanical stress, Navy Type III has the best power handling capabilities. Applications include ultrasonic cleaners, cell disruption, phacoemulsification, and high power ultrasonics.
