1. Is the vibration detection circuit of the piezoelectric ceramic crystal simple? How to operate?
The vibration detecting circuit of the piezoelectric ceramic crystal is very simple, so in the first question, the answer is yes. Its specific operation is to connect its two electrodes directly to the oscilloscope, and the voltage across it is mv level. If the signal amplitude is too low, then you can use an amplifier, etc., first amplify the signal, and then connect it to the oscilloscope.
2. Piezoelectric ceramic transducer, in the process of burning silver of piezo ceramics poling at 800 ° C, if its sticky sheet is serious, then, what is the reason? And, how to use the vibration of the piezoelectric ceramic crystal?
Piezoelectric ceramic crystal in the process of burning silver at 800 ° C, if the problem of serious sticking is present, the root cause is the problem of molecular slurry. As for how to use the vibration of the piezoelectric ceramic piece, the sum is as simple as connecting it to the secondary AC voltage of the small transformer.
3. What is the sound of a piezoelectric cylinder transducer? And, is there a difference between its series and parallel?
The sound of a Pzt material piezoelectric ceramic is determined by the natural frequency of the ceramic sheet, and its natural frequency is determined by the stiffness of the piezoelectric ceramic sheet.
The series and parallel connection of piezoelectric ceramic sheets are obviously different. Therefore,about question two, the answer is yes, that is, it is definitely different. As for the specific difference, it is not believed here. In the future, if there is a chance, it will be explained in detail.
