    Abstract: A system and method for determining eccentricity of a casing and a rotor of a gas turbine includes a plurality of stationary distance detectors coupled to the casing at known circumferential positions and a rotating distance detector coupled to the rotor or a blade in or near an axial plane defined by the stationary distance detectors. The stationary distance detectors transmit wireless signals to one another to determine a first series of distance measurements between each pair of stationary distance detectors. The rotating distance detector transmits wireless signals to each of the stationary distance detectors, as the rotor is spun, to generate a second series of distance measurements. The measurements are transmitted, over a wireless local area network, to a remote computing device that processes the distance measurements into an eccentricity plot. An optional base station may be used to generate the wireless network.
