I am not a great expert in vibration analysis. Just a bit of experience, on the field, with our rotating machines. I try to understand more the behaviour of the machines, with the vibrations. It helps for the maintenance
I am using a Vibrotest 80 from Bruel and Kjaer. With an "overall" recording, we have the possibility to see the acceleration and the BCU.
I understand that the BCU is the Bearing Condition Unit. But it is correlated to the acceleration ? If the bearing is worn, the BCU is high, and the acceleration is high ? Actually, I though this, until I find a case where the BCU is very low, and the acceleration is very high. Therefore, I am lost
Do you have an explaination ?
Thanks a lot for your help
