measuring ultrasonic impedance frequency phase vs electrical components ceramics piezoelectric transducers testing equipment

Impedance analyzer is the instrument applicable for measuringimpedance-vs.-frequency and phase-vs.-frequency characteristics ofcomplex impedance electrical components, as for instance: ultrasonicdevices, piezoelectric ceramics and piezoelectric transducers forultrasonic cleaners and ultrasonic plastic welders, underwater acoustic transducers, sensors, magnetostrictive transducers, and for manyother industrial and medical applications.

Impedance analyzer is the instrument essential in every production of ultrasonic equipment for components measurements and qualification and for resonant frequencies measurements. PV70A is the instrument which can easily replace much more complex and more complicated, also many times more expensive instruments from Agilent/HP, as for instance: HP Impedance GainPhase Analyzer 4194A, Agilent E5100A, Network Analyzer, HP 3563A,Control System Analyzer etc. It is also very easy to use PV70A (by engineers or ordinary production workers).

Users can see resume of all important impedance elements and parameters from the same impedance-frequency diagram directly after a single measurement step.

Here we will focus our attention only to impedance measurements of piezoelectric elements. PV50A,PV70A impedance analyzer is optimized to extract the following complex-impedance parameters of piezoelectric components:

Series resonance frequency Fs,

Parallel or anti resonance frequency Fp,

Half power frequency points F1 & F2,


Static capacitance C0,

Dynamic resistance R1,

Dynamic capacitance C1,

Dynamic inductance L1,

Free capacitance CT,

Mechanical quality factor Qm,

Electromechanical coupling coefficients Keff, Kp, K31 & K33,

And also to draw characteristic impedance-phase curves, such as admittance characteristic graphics, impedance characteristic graphics, admittance polar plot, impedance polar plot, and logarithmic plot.
