Measuring Methods
1) Resonant frequency / Resonant impedance The piezo electric diaphragm should be clamped at a node point (as shown in the following figure) to be free from any mechanical stress. Measure its resonant frequency and resonant impedance by using a vector impedance analyzer or equivalent. When the input frequency is swept within 100 Hz to 5 KHz, the resonant frequency is defined as the frequency where the impedance shows minimum value. This impedance should be the resonant impedance.
2) Static capacitance The electrostatic capacitance should be measured at 120 Hz by using an L.C.R. meter (ex. HP4194A(H.P.)) or equivalent. The part should be clamped in the same way as the measurement or re……
