Customized piezoelectric transducers manufacturers take you to understand the piezoelectric material selection of piezoelectric ceramic transducers:
1. Piezoelectric strain constant
Indicates the magnitude of the strain generated when the piezoelectric crystal is subjected to an external unit voltage.
2. Frequency constant
The manufacturer of customized piezoelectric transducers tells you that the product of the natural frequency of the piezoelectric wafer and its thickness is a constant, called the frequency constant N, from which it can be seen that the thickness of the wafer is inversely proportional to the resonance frequency, and the frequency of the ultrasonic wave mainly depends on the thickness of the wafer and the thickness of the wafer. The speed of sound in .
3. Piezoelectric voltage constant
Indicates the magnitude of the voltage gradient generated when the piezoelectric crystal is subject to external unit stress. The manufacturer of customized piezoelectric transducers tells you that these two parameters are important parameters to measure the emission performance of piezoelectric crystal materials. The larger the parameter, the better the emission performance and the higher the emission sensitivity.
