High Sensitivity Soft Pzt Ceramic Powder Piezoceramic Material
Product Description
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.
