Vibration Analysis

Overall vibration is the total vibration energy measured within a frequency range. Measuring the overall vibration of a machine or component, a rotor in relation to a machine, or the structure of a machine and comparing the overall measurement to its normal value (norm) indicates the current health of the machine.
A higher than normal overall vibration reading indicates that something is causing the machine or component to vibrate more.

Vibration is considered the best operating parameter to judge low frequency dynamic conditions such as imbalance misalignment, mechanical looseness, structural resonance, soft foundations, shaft bow, excessive bearing wear, or lost rotor veins.
