High-power Ultrasonic Impedance Analyzer

Impedance Analyzer is mainly used for piezoelectricity element impedance analysis and
parameter calculation. Before using piezoelectricity element, you need to know
its major parameters: resonance frequency Fs, antiresonance frequency Fa, half
point power F1 and F2, the max. admittance Gmax, direct capacitance C0, dynamic
resistance (R1, C1, L1), free capacitance CT, free dielectric constant 33T,
mechanical quality factor Qm, electromechanical coupling factor Keff, plane
electromechanical coupling factor Kp and so on.

This instrument can measure admittance characteristic curve of piezoelectricity element
(the admittance is equal to reciprocal of impedance) and analyze and extract
the above needed parameters. With this instrument, you can gain four characteristic
curves of piezoelectricity element (admittance characteristic graph, impedance
characteristic graph, admittance coordinate graph, impedance coordinate graph).
Moreover, it is easy to save and print the measured result.

This instrument combines the hardware and PC software for impedance analysis. The
hardware system finishes impedance measure, and the PC software finishes impedance analysis and parameter extraction power.

This instrument is used for guiding piezoelectricity element's testing and using.
It is a synthetic solution of piezoelectricity element's measurement and analysis.
Moreover, it can evaluate and test parameters of the piezoelectricity element.
