High Quality Full Touch Screen Ultrasonic Impedance Testing Instrument With High Sensitivity

Ultrasonic impedance detector, also known as ultrasonic frequency measuring instrument, ultrasonic transducer parameter analyzer, ultrasonic transducer impedance tester and ultrasonic performance analyzer. This instrument is composed of hardware and software. The impedance analyzer can accurately measure in the impedance range and wide frequency range. It uses the object to have different conductive effects. When a fixed low-level current is added to the object surface, it calculates the parameters and performance of various devices and equipment of the object through the impedance.

The impedance measurement of piezoelectric devices is a 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, greater admittance Gmax, electrostatic 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, Five characteristic curves of piezoelectric devices (admittance characteristic diagram, impedance characteristic diagram, admittance polar coordinate diagram, impedance polar coordinate diagram and logarithmic coordinate diagram) can be drawn.

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, hydroacoustics, magnetostrictive materials, ultrasonic pulverizers, ultrasonic atomization, ultrasonic tooth cleaning, ultrasonic ranging, phacoemulsification, ultrasonic descaling, ultrasonic motors, etc.
