Applications:

Piezoceramic transducers for the transmitting and receiving of ultrasonic signal needed in level sensors for non-contact level sensing of liquids and bulk solids.

Ultrasonic level sensors are widely used for non-contact level sensing of liquids and bulk solids. The sensor comprises piezoceramic transducer which can emit high frequency ultrasonic waves. The piezoceramic transducer is mounted above the liquid surface being measured. The distance of liquid surface from the sensor is determined by sending a short ultrasonic pulse and measuring the time it reflects back from the liquid surface.

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.
