What Is an Impedance Analyzer?

The impedance analyzer can accurately measure in the impedance range and a wide frequency range. It uses different conductive effects of the object. When a fixed low-level current is applied to the surface of the object, various devices, equipment parameters and Pros and cons.

The impedance analyzer is mainly suitable for the measurement of impedance characteristics of various ultrasonic devices, including: piezoelectric ceramics, transducers, ultrasonic cleaners, ultrasonic plastic welding machines, hydroacoustics, magnetostrictive materials, ultrasonic pulverizers, ultrasonic atomization , Ultrasonic teeth cleaning, ultrasonic ranging, ultrasonic emulsification, ultrasonic descaling, ultrasonic motor, etc.

The characteristics of the impedance analyzer are: easy to use, combination of indicators and graphics, accurate parameters, low price, and strong guidance for production.

The impedance measurement of a piezoelectric device is a prerequisite for the correct use of the device. For a piezoelectric device, its main parameters can be obtained through an impedance analyzer, including: resonance frequency Fs, anti-resonance frequency Fp, half power points F1 and F2, maximum admittance Gmax, static capacitance C0, dynamic reactance R1, dynamic capacitance C1, Dynamic inductance L1, free capacitance CT, free dielectric constant, mechanical quality factor Qm, electromechanical coupling coefficients Keff, Kp, K31, K33, etc., and can draw five kinds of characteristic curves (admittance characteristic diagram, impedance characteristic diagram) of piezoelectric devices , Admittance polar diagram, impedance polar diagram, logarithmic diagram).
