Application field of ultrasonic frequency measuring instrument

This instrument is applicable to all kinds of ultrasonic devices, including Ultrasonic Transducers, ultrasonic amplitude transformers, ultrasonic molds (tool heads), piezoelectric ceramics, transducers, ultrasonic cleaners, ultrasonic plastic welding machines, hydroacoustic, magnetostrictive materials, ultrasonic grinders, ultrasonic atomization, ultrasonic dental cleaning, reversing radar, ultrasonic ranging, ultrasonic emulsification, ultrasonic descaling, ultrasonic motors, And all other devices and equipment that use piezoelectric and ultrasonic. Especially in the process of ultrasonic equipment development and production, how to know whether the ultrasonic parts and components involved by engineers meet the requirements, their quality, performance and parameters, it is necessary to use ultrasonic frequency measuring instrument to detect. Transducer: the admittance circle diagram shall be free of parasitic circles, the resonant frequency shall be close to the design frequency as much as possible, the dynamic impedance shall be low, the quality factor Qm shall be close to the design requirements, and the capacitance shall match the circuit. Piezoelectric ceramic chip: the device can be judged directly from the admittance circle diagram and logarithmic coordinates. If there are delaminations or cracks in the ceramic chip, the logarithmic curve will have multiple peaks, and multiple parasitic small circles will appear on the admittance circle diagram. Whether the design, processing and assembly of the horn are reasonable or defective can be seen directly on the guide circle diagram. For the production and processing of ultrasonic welding machine, the results of admittance circle are used to analyze the state of the welding machine. Through the analysis of parameters and graphics, the existing problems of the welding machine are found. Production and processing of ultrasonic cleaning machine: the selection of vibrator requires that its vibration performance be as consistent as possible (bandwidth, quality factor, resonance frequency, dynamic impedance). On the admittance circle diagram, there is no parasitic circle or parasitic circle near the resonance point as far as possible. It can analyze and measure the impedance characteristics of transducer manufacturing, incoming material inspection, bonded transducer and cleaning machine. The whole machine measurement of the cleaning machine can calibrate the resonant frequency and static capacitance of the machine to match the power supply, and can analyze the characteristics of its new resonant point, impedance, capacitance after water injection and vibration mode of the whole machine.
