Piezoelectric Components Ultrasonic Impedance Analyzer

The impedance analyzer is mainly used for measuring the impedance characteristics of various ultrasonic devices, including piezoelectric ceramics, transducers, ultrasonic cleaning machines, ultrasonic plastic welding machines, underwater acoustic, magnetostrictive materials, ultrasonic pulverizers, ultrasonic atomization, ultrasonic tooth cleaning, ultrasonic ranging, ultrasonic emulsification, ultrasonic descaling, ultrasonic motor and other ultrasonic equipment.

The characteristics of impedance analyzer are: easy to use, combination of index and graph, accurate parameters, low price, and strong guiding ability for production.

It is a prerequisite for the correct use of piezoelectric devices to measure the impedance. For piezoelectric devices, the main parameters can be obtained by impedance analyzer, including: resonance frequency FS, anti resonance frequency FP, half power points F1 and F2, maximum admittance Gmax, electrostatic capacity C0, dynamic reactance R1, dynamic capacitance C1, dynamic inductance L1, free capacitance CT, free dielectric constant, mechanical quality factor QM, electromechanical coupling coefficient keff, KP, K31, k33, etc., and can draw piezoelectric voltage Five characteristic curves of electrical parts (admittance characteristic diagram, impedance characteristic diagram, admittance polar coordinate diagram, impedance polar coordinate diagram and logarithmic coordinate diagram).
