DEVICE FOR TESTING A BIMORPH PIEZOELECTRIC ELEMENT |
| 摘要 |
The proposed device for testing a bimorph piezoelectric element contains a measuring unit, a series-oscillating circuit with transformer coupling, and an oscillator. The measuring unit contains a threshold element, a pulse former, and a pulse counter. The piezoelectric element to be tested is inserted in the oscillatory circuit.
