EMT226 Bearing Vibration Tester Vibration Analyzer

High frequency faults in rolling bearings and gearboxes have the following characteristics: significant vibration and impact in the early stages of the fault, gradually returning to normal values as the fault progresses, while the vibration energy value increases significantly. The impact signal is sensitive, but not stable enough; The vibration energy value is not sensitive enough, but it will steadily increase with the fault. This requires attention to both high-frequency impulse values and low-frequency effective values when diagnosing such faults. EMT226 can meet the above requirements, not only measuring the peak and average values of high-frequency vibration acceleration, but also measuring the effective value of low-frequency vibration velocity; At the same time, this instrument also provides high-frequency judgment standards and low-frequency vibration intensity standards (ISO2372) to jointly judge the status of bearings and gears.
