Wireless Vibration Monitoring
Wireless Vibration Monitoring
(OP)
I need to make use of wireless on-line vibration monitoring on blades of a rotating fan. What technologies or techniques are available other than scanning laser vibrometers?

RE: Wireless Vibration Monitoring
However, you could mount strain gauges on the fan blades or shaft and monitor the stresses during rotation by use of a transmitter. The stress readings could be calibrated to an equivalent vibration level.
RE: Wireless Vibration Monitoring
Stress patterns by thermal emissions.
It's a camera that gives you stress contours. I don't know if it can cope with a rotating target.
SDRC or GenRad used to sell the system.

Good luck

Incidentally you shouldn't use a minidisc for analytical work unless you really understand the compression formula they've used, or disabled it somehow. As I remember the algorithm only retains (worst case) 25% of the data!

For the frequencies of fan blades I think you should be OK.
