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 resonant frequency / resonant
impedance mentioned above.
