Impedance Analyzer

Impedance Analyzer / Horn 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 extractthe above needed parameters. With this instrument, you can gain four characteristic curves of piezoelectricity element (admittance characteristic graph, impedancecharacteristic 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.

Impedance analyzer is widely applied in ultrasonic industries,including ultrasonic plastic welder, ultrasonic cleaner, ultrasonic transducer,ultrasonic electro machining, underwater acoustic transducer, ultrasonic sensor, piezoelectric ceramic, parking sensor, medical ultrasonic device, ultrasonic scaling device, ultrasonic horn, ultrasonic welding head, ultrasonic grinder, and ultrasonic emulsor.
