Piezo Ceramic Ring
a.Types of Piezoceramics
b.Piezoelectric Ceramics:Piezoelectric Material PZT8
PZT8 piezoelectric ceramic has high mechanical quality factor , high electromechanical coupling factors , high stability , low dissipation factor, compatible with high voltages and high mechanical loads, so widely used in ultrasonic cleaner, ultrasonic welding, ultrasonic detector, ultrasonic motor, ultrasonic transformer and other high-power emanant transducers and so on.
c. Piezoelectric Ceramics:Piezoelectric Material PZT4
PZT4 piezoelectric ceramic has characteristics similar to P8 , but PZT4 is the middle power transmitting and receiving matrial,. It’s widely used in ultrasonic cleaners, ultrasonic welding, vibratory motors. high frequency transducers and stress pressure sensors and so on.
d. Piezoelectric Ceramics:Piezoelectric Material PZT5
PZT5 piezoelectric ceramic has the function of large displacements and high sensitivity, which is the soft material, so widely used in flow meters, medical ultrasound, level sensors, microphones and so on
