Abstract:
A system and method for monitoring a gap between a vibrational body and a reference is achieved by monitoring the resonant frequency of the vibrational body. A portion of the vibrational body is fixed a given distance from the reference by a rigid mounting system. A resonant frequency of the vibrational body is received. Then, a quantity standing in known relation to an approximate change in the length of the gap is determined, based upon the resonant frequency.
