35MM Diameter Ceramic 35Khz 800w Ultrasonic Welding Piezoelectric Transducer
Description:
Ultrasonic transducers are actually piezoelectric ceramics whose frequency is the same as their resonant frequency, using the piezoelectric effect of the material to convert electrical energy into mechanical vibration. Under normal circumstances, ultrasonic waves are first generated by an ultrasonic generator, converted into mechanical vibration by an ultrasonic transducer, and ultrasonic waves are generated by an ultrasonic derivation device and an ultrasonic receiving device.

Method for detecting piezoelectric ceramic sheets:
Piezoelectric ceramic sheets are a synthetic piezoelectric material. When subjected to external pressure, charges are generated on both sides, and the amount of charge is proportional to the pressure. This phenomenon is called the piezoelectric effect. Piezoelectric ceramics have a piezoelectric effect, that is, deformation occurs under the action of an external electric field, so a piezoelectric ceramic sheet can be used as a sounding element.
By using the piezoelectric effect of the piezoelectric ceramic sheet, the multimeter can be used to judge whether it is good or bad.
Take the two poles of the piezoelectric ceramic piece out of the two wires, then place the ceramic piece on the table flat, connect the two leads to the two test leads of the multimeter, turn the multimeter to the minimum current block, and then gently press the ceramic piece with the pencil eraser. If the pointer of the multimeter is obviously oscillated, the ceramic piece is intact, otherwise the description is damaged.
