FUNCTIONS---Used for measuring periodic motion, to check the imbalance and deflecting of moving machinery, specifically designed for present measuring various mechanical vibration. So as to provide the data for the quality control, run time and equipment upkeep.ACCURATE MEASUREMENT---The vibrometer use the high-performance acceleration meter, realize the repetitiveness and accurate measurement.It has the function of testing axle bearing situation.WORKING PRINCIPLE---Vibration meter(also called also called vibration severity) uses Piezoelectric Acceleration Transducer transfer the vibration signal in to electrical signal, analyze the input signals, and show the Acceleration, speed, shift of the vibration.WIDE APPLICATION---Widely used in the lines of Power, petrochemical, machinery manufacturing, metallurgy, vehicles, etc.
