Vibration testing machine features and advantages

◎ Humanized operation and control, using professional measurement and control software control, making the equipment work more stable and reliable

◎ The machine is made of composite industrial materials, precision machining, ultra-quiet

◎ The panel is made of magnesium aluminum alloy material, which can completely isolate the magnetic field interference and effectively prevent the magnetization of the measured object

◎ Sweep frequency, fixed frequency and multi-stage operation mode, adapt to different industry test requirements

◎ High precision frequency output, four-point synchronous excitation, even table vibration

◎ Strong antimagnetic and anti-interference ability

◎ Safe and reliable protection function

◎ The body is cooled by an efficient and low noise fan to ensure long-term continuous operation

◎ Using closed-loop control (negative feedback control) principle, the sensor can automatically control the shaking table after collection to ensure the output and test accuracy

◎ With constant vibration amplitude vibration and constant acceleration vibration

◎ The system is equipped with high-precision vibration sensor to collect acceleration, amplitude and frequency in real time
