Relationship between welding spot and wave force of piezoelectric ceramic crystal

1. What is the vibration detecting circuit of a piezoelectric ceramic crystal?

The vibration detecting circuit of the piezoelectric ceramic transducer is actually not complicated, just connect the two electrodes to the oscilloscope. However, it should be noted that the voltage across the piezo ceramics poling chip is the level. Also, if the signal amplitude is too low, a low-noise amp can be used to amplify the signal for observation.

2. What should be paid attention to during the welding process of piezoelectric ceramic crystal?

For the welding work of piezoelectric ceramic transducer, there are some precautions. In particular, it is in the welding temperature, it should not be too high; in the welding time, it is not suitable for the process, otherwise it will affect the welding. in turn, The quality affects the use of piezoelectric ceramic sheets. The welding time of soft piezoelectric ceramic is generally only a few seconds.

3. What is the relationship between the waveform and time of the piezoelectric ceramic transducer to generate electricity and the force?

If the force of the periodic change continues to act on the piezoelectric cylinder transducer, then the piezoelectric ceramic crystal will continue to generate electricity, and its waveform is close to a sine wave. And if it is a momentary force, then it is close to the pulse on the waveform.
