What is the principle of ultrasonic impedance analyzer?

The ultrasonic impedance analyzer applies a fixed low-level current to the surface of the object, uses the different conductive effects of the object, and measures various parameters and properties of the object through impedance calculation. It can measure the frequency, impedance, capacitance and other parameters of the ultrasonic transducer, horn, and mold. During measurement, the instrument will send out a pulse signal, detect the current and voltage, and calculate the impedance. For example, when measuring a 28kHz transducer, you can start pulsing from 27kHz, increase the frequency gradually until the resonant frequency is found, and then calculate the impedance through the voltage and current at this frequency. In addition, the instrument can also display the curve during measurement to help observe whether the transducer has internal injuries or clutter.

Application of Impedance Analyzer in Electrochemical System

Impedance analyzer is also widely used in electrochemical system. It obtains information by applying an AC signal and measuring the system's response to this signal. Impedance is a property that describes the response of a circuit or system to an AC signal, including parameters such as resistance, inductance, and capacitance. By measuring and analyzing impedance, valuable information such as electrode interface characteristics, electrolyte conductivity, and reaction kinetics can be obtained. Impedance analyzer usually consists of an AC power supply, an electrochemical cell, and a measurement control system. It can provide a stable AC signal and perform data processing and analysis by controlling and recording parameters such as voltage, current, and phase.
