I have a severe "beating" phenomenon that is affecting the overall 1X vibration levels on a 1775 rpm motor that is in close proximity of a rather large generator. I am quite sure it is "beating" because when I adjust the span and # of lines on my meter I can differentiate...

A Motor that drives our centac air compressor has suddenly increased vibration readings with a dominant peak at 2X which is extremely close to being BSF. It increased over 7 days from .058ips to .142ips. There is a cyclical noise being emmitted from the bearing that I can detect using...

Thank you all, this information has been very helpful!

I had been having trouble with taking measurements using my 2120 CSI analyzer. on some readings the overall measurements have been much higher than the last. The difference in the spectrum being that there was a peak between 0 and 2.5hz that had a ski slope effect. This peak did not show up...

I am looking for some guidance for determining alarm setpoints. I am aware that ASME section XI has some guidance, but in my experience this is wholly inadequate to maintain a quality Predictive Program. I am also aware that much of the alarm status is based on historical component performance...

I to am new in the vibration field and might have some good advice. The best place to get training is the vibration institute. CSI and Bentley Nevada also have some quality training, but whenever you get envolved with vendors they try pretty hard to push their products. You want to find a...

I just took a job in a nuclear power plant as a systems engineer. I will be focusing on vibrational analysis of turbines. I am fresh out of school so I have only a little internship experience. Does anyone have any suggestions for some books or reference material that I should look at so I...
