1. What is the resonant frequency of a piezoelectric ceramic crystal?
For the resonant frequency of the 1Mhz piezoelectric ceramic crystal, the relevant factors are connected with the thickness of the ceramic sheet and the size and diameter of the piezo ceramic sheet. If the piezoelectric ceramic piece has a diameter of 10 - 25 mm, its resonance frequency is in the range of 15 to 85 kHz.
2. Piezoelectric ceramic sheet, if it is connected to the ultrasonic generator, then, can DC be used?
If the piezoelectric ceramic piece is connected to the ultrasonic generator, then DC power cannot be used. So, the answer to this question is no. Also, it should be noted that the output power of the generator cannot exceed the output voltage requirement of the piezo ceramic disc transducer, In addition, in terms of power, it is also necessary to pay attention.
3. Can I use ordinary piezoelectric ceramic sheets for the piezoelectric ultrasonic humidifier? And, on the piezoceramic ring piezo sensor sheet, is it possible to use ultrasonic welding leads?
The piezoelectric sheet in the ultrasonic humidifier can be a conventional piezoelectric ceramic sheet. So, question one, the answer is yes. Moreover, in terms of frequency, it is mostly at 1.6MHz. As for the second question, if it is normal welding, then there is no impact, but sometimes, it is also necessary to pay attention to some matters, as to what will be detailed in the future.
