VT700 Dynamic Balancing Measuring Instrument Technical Parameters:
The VT700 dynamic balancing measuring instrument is simple to operate with human-machine dialogue. It has high testing and analysis accuracy. With a brand-new design, it provides fast testing and analysis with clear graphics. The large-screen color LCD display with Chinese characters makes it very convenient for on-site dynamic balancing measurement of rotating machinery such as steam turbines, water turbines, agricultural machines, centrifuges, fans, and water pumps, as well as for correcting dynamic imbalance and signal analysis (waveform display and FFT analysis). It can also be used with balancing machines to directly replace the balancing machine electrical box for retrofitting old balancing machines. It is a special tool for detecting dynamic balance in factories, mines, and technical appraisal departments. Especially in dynamic balancing detection of rotating machinery, just press a button to know the total vibration value of the tested machine and the amount of imbalance caused by the rotating part, making it clear at a glance whether the product is qualified. It can not only perform dynamic balancing on equipment on-site but also conduct vibration detection and analysis. It digitally displays the equipment's speed, amplitude, and phase, and ultimately obtains the required balancing weight (add/remove) and phase. All functions are realized in a briefcase, making it truly portable. Its main functions are the same as the VIBROPORT series universal vibration tester from Schenck, Germany.

Main Functions
● Multi-functional: can be used as a tachometer, vibration measurement, and vibration signal analysis. Especially has all functions of dynamic balancing measurement (instant display of unbalanced vibration and phase).
● Frequency analysis of machine vibration (FFT max 1024 points)
● Automatically uses the trial weight method to measure influence coefficients and calculate single and double plane optimal counterweights, or directly calculates optimal counterweights based on measured original vibration with known influence coefficients. It can calculate while measuring or input all at once. (Option to remove trial weight or not)
● Ability to calculate the calculated optimal counterweight to left and right selected angles.
● Frequency analysis capability to detect same-frequency, half-frequency, and double-frequency vibration components of the rotor.
● Simple operation with automatic prompts, usable by general personnel
