Product Description
To detect paper refeeding, an accuracy of 1mm and sharpness are necessary. Traditional bending oscillators, which have a frequency of more than 70 kHz, will lose their practicality. Therefore, the thickness of high-frequency piezoelectric ceramics is used for longitudinal vibration.
In this case, the acoustic impedance matching of piezoelectric ceramics and air is very important.
The difference between the acoustic impedance of the piezoelectric ceramic and the acoustic impedance of the air is large, so the vibration radiation loss of the piezoelectric ceramic is large.
Therefore, a special material and a piezoelectric ceramic are adhered as a sound-integrated layer, and the matching with air is measured. This structure can realize hundreds of kHZ ultrasonic sensors
