Here You Go.

Industrial vibration analysis is a measurement tool used to identify, predict, and prevent failures in rotating machinery. When analyzing machine frequency vibrations, (frequency analysis) it is normal to find a number of important frequencies that are directly related to the movement of various parts of the machine. Vibration may influence the durability and reliability of machinery systems or structures and cause problems such as damage, abnormal stopping, and catastrophic failures. Vibration measurement is an important countermeasure to prevent these problems from occurring.

There is so much data available to  us in today's world. Smart homes, smart thermostats, smart light bulbs, everything is "smart." If you went out and bought one of the smart devices, would you use it? Or would you use it just like your previous "non-smart" thermostat? If you are going to pay a premium for the device, you most likely will use some of the new features on it.

A common situation... 20 years ago someone decided that utilizing vibration analysis was a good idea in your plant. Maybe the idea came from a vendor or an internal Predictive Maintenance (PdM) guru. Either way you evaluated it and it just didnt make sense to have an internal team dedicated to this so you decided to outsource it.

How did you choose which company to use?

Was it  a simple decision and go with the person who was bringing the idea to your plant? Did you develop a specification and go out for bid? How you made this determination is something to review down the road.
