Applications:
Piezoceramic transducers to produce ultrasonic signal for distance measurement needed in automotive backup sensors.
Back up sensor is one of the applications of ultrasonic transducer in the air. Using the piezoelectric ceramic transducer to transmit the ultrasonic signals and receive the echoes, the distance of an obstacle is thus obtained by calculating the time lag between signal transmitting and receiving.
PZT Material:
- PZT4 Piezoelectric ceramics have a double behavior of receiving and transmitting, with higher sensitivity and lower dielectric loss.
- PZT5 Piezoelectric ceramics have higher electro-mechanical coupling coefficient, the moderate dielectric constant and higher sensitivity.
- PZT8 Piezoelectric ceramics of high power transmission type have good piezoelectric property, high mechanical strength, high coercive field, low dielectric loss in strong fields.
