        High Sensitivity Soft Pzt Ceramic Powder Piezoceramic Material


Typical soft 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.
