Ultrasonic Impedance Analyzer For 1khz-5mhz Piezoelectric Ceramic Testing
The impedance analyzer is mainly applicable to the measurement of impedance characteristics of various ultrasonic devices, including piezoelectric ceramics, transducers, ultrasonic cleaning machines, ultrasonic plastic welding machines, underwater acoustics, magnetostrictive materials, ultrasonic pulverizers, ultrasonic atomization, ultrasonic teeth cleaning, ultrasonic ranging, ultrasonic emulsification, ultrasonic descaling, ultrasonic motors and all other ultrasonic equipment.
The characteristics of impedance analyzer are: easy to use, combination of index and figure, accurate parameter, low price, strong guidance for production, etc.
The impedance measurement of piezoelectric devices is the prerequisite for the correct use of devices. 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 the piezoelectricity can be drawn Five characteristic curves (admittance characteristic diagram, impedance characteristic diagram, admittance polar diagram, impedance polar diagram and logarithmic coordinate diagram) of electrical appliances.
