Product description

Piezoelectric ceramic ring

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

Applications includes:

high powder piezo ultrasonic welding transducer

Features :

Sizes from 3mm up to 180mm
Thickness from 0.2mm up to 25mm
Choice of metallisation (Silver, Nickel, Gold and others on request)
Wide choice of PZT formulations

Piezoelectric Ceramic Material: PZT-82

PZT-8 series

This material range is used in high power applications, even though its piezoelectric activity level is slightly lower than PZT-4 series types. With an extremely high mechanical quality factor and extremely low loss factor, PZT-8 series materials have the ultimate power handling capability.

Piezoelectric elements technical data:
Dimensions:	out diameter 60mm, inner diamter 30mm, height 10 mm
Radial frequency Fr:	25KHz ± 1.5KHz
Mechanical Coupling coefficient K31	≥ 0.325
Dielectric Loss tg δ:	≤ 0.3%
Static capacitance Cs:	1800pF±12.5%

Test Condition: 25±3 °C 40~70% R.H.
fr, Zm, Kr => Radial mode vibration
Cs tanδ => LCR meter at 1KHz 1Vrms

Typical "hard" PZT characteristics include:

Wide range of frequencies in transmit and receive (sub-audible, audible, ultrasonic)
High output, low drive material
High frequency, fast response time
High sensitivity for active or passive use
Ability to use with low voltage or high voltage drive circuits
Good mechanical and acoustic coupling
Wide variety of shapes and sizes that can be customized to meet specific requirements and applications
Wide variety of compositions that can be selected to meet specific requirements and applications
Quality of each PZT component is ensured by a rigorous testing regimen. Characteristics such as frequency, capacitance, dissipation, coupling, d33 and mechanical properties are measured and verified against our / customer provided specifications.

Yuhai piezo materials "hard" PZT includes:

P-41	is equal to PZT-4D hard PZT. It is designed for higher dielectric constant, high Q m , high coercive field, high coupling and high stiffness required high power high driving transducers etc.
P-42	Is a modified hard PZT, higher dielectric constant of P-41.
P-43	is a modified hard PZT. It is developed for higher dielectric constant, high coupling and high stiffness required high power high driving etc. transducers
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.
PCrN-4	is a modified PZT dedicated for extremely high power high driving etc. transducers with higher power handling capability than DL-43, dual function of receiver and transmiting transducer.
PbaS-4	is a modified hard PZT developed for extremely high dielectric constant, high Q m , high stiffness and low dissipation factor required high frequency transducers etc.
