Accelerometer Frequency Response - Basics
Accelerometer Frequency Response - Basics
(OP)
I am trying to select accelerometers for turning dryer cans in a Paper Mill. Given the cans diameter and our machine speed, the cans run between 55 and 110 rpm. I have some specs for accelerometers, but I am unsure about what I am reading.
From two salesmen, I have specs stating:
1) 120-360,000 cpm @ +/- 10%
60-600,000 cpm @ +/- 3dB.
2) 300-600,000 cpm @ +/- 5%
240-720,000 cpm @ +/- 10%
120-1,200,000 cpm @ +/- 3dB
I am not an expert, but do these look as if they would function properly? Given my rpm, these accelerometers look like they are sized for something a lot faster then my application.
Thanks in advance for any help.

I am just not that familiar with vibration monitoring. I understand the roller bearings are turning at a faster rpm then the dryer can. However the inner race would turn as the dryer can would. This makes me think I do need more low end for that portion.
This is going to be a major installation, so I want to feel confident in the final decision.
Any other thoughts anyone?
