Why vibrations?

Why vibrations are the best way to determine machine condition without stopping it?

Machines generates vibrations from the first moment of work till the end of explotation time. Due to this fact this parameter is one of the best to control machine condition.

You don't need to shut down the machine from its normal operations, you don't need to disassemble machine to install the sensors and measuring tools. You can perform measurement of the machine during its normal operations. Measurements of the one machine takes only few minutes.
