Nickname: Resonant Test System; Variable Frequency Resonant; Variable Frequency Resonant Test; series resonant



 





 



 




Feature


 



1. The series resonant device has overvoltage, overcurrent, zero start, system detuning (flashing) and other protection functions, overvoltage and overcurrent protection value can be adjusted according to user needs, and the flashback protection action when the sample flashes and can record the flashback voltage value for test analysis.



2. The weight of the whole series resonant device is very light, the maximum does not exceed 40kg, which is convenient for on-site use.



3. The series resonant device has four working modes, which is convenient for users to choose flexibly according to the site situation, and the working modes of increasing the test speed are: fully automatic mode, manual mode, automatic tuning manual boost mode.



4. It can store and print data in different places, and the stored data number is a number, which is convenient to help users identify and find.



5. The frequency starting point of the series resonant device can be set arbitrarily within the specified range when the frequency is automatically swept, and the frequency sweeping direction can be selected up and down, while the large LCD screen displays the scanning curve, which is convenient for users to intuitively understand whether the resonance point is found.



6. The use of DSP platform technology, which can easily add or remove functions and upgrades according to user needs, and also make the man-machine exchange interface more humane.



 





 



 





 



 



Q: What do you mean by resonant frequency?

A: Resonant frequency is the natural frequency where a medium vibrates at the highest amplitude. Resonant frequency is usually denoted as f0. Resonance is witnessed in objects in equilibrium with acting forces and could keep vibrating for a long time under perfect conditions.



 



Q: What does resonant frequency depend on?

A: The defined resonant frequency is determined by the size and shape of the object, along with the material it is made from. Resonance occurs when the frequency of an initial object's external vibration matches the resonant frequency of a second object.
