Air Conditioner Vibrations
Air Conditioner Vibrations
(OP)
Hi all,
I want to install a vibration sensor (accelerometer?) onto an air condition unit to monitor its vibrations (yes, I'm bored; I basically want an excuse to get some data so I can put my signal processing skills to good use). But since I don't know much about mechanical engineering, I was wondering if you guys can help me out here.
First, what kind of vibrations can I expect? What's the acceleration going to be in terms of g's (gravity)? What about spectrum distribution (highest/lowest freq I can expect to see)?
Second, anyone can recommend a brand+model of accelerometer that might be good for this?
Thanks in advance!
Cheers,
Steven

RE: Air Conditioner Vibrations
Total rms acceleration will probably be less than 20g, that's enough to cause fatigue problems on engines.
B&K make good ones, as do Endevco. You can hire them from places like TechRentals.
Pretty expensive way to relieve boredom!

RE: Air Conditioner Vibrations
Do you have the means to properly power and condition the signal? Feel free to contact me directly if you need assistance.
