1. A system for monitoring rotating machinery having a shaft and circumferentially disposed extensions rotatable with said shaft and spaced apart from one another, the system comprising:

  • a plurality of proximeters positioned proximate to said rotating machinery and each proximeter being operable to measure and transmit resonant vibration frequency and bending amplitude data for said rotating machinery derived from a transit time between said individual rotating extensions, along with distance data derived from signal amplitude data for a proximeter signal strength of the bending, wherein said plurality of proximeters are positioned so as to enable mapping a resonance period of said rotating machinery; and

    a processor electrically coupled to receive said data and configured to correlate said data and thereby produce an assessment of operational health for said machinery.
