Abstract
A method for measuring shaft deflection in a turbomachine includes communicating one or more signals from a controller to a plurality of sensing devices positioned on a shaft of a turbomachine across an airgap defined between a rotating antenna positioned around the shaft and a stationary antenna aligned with the rotating antenna in a radial direction to excite the plurality of sensing devices; receiving a parameter of the shaft in a plurality of circumferentially spaced locations from the excited plurality of sensing devices; determining a magnitude of a deflection in the shaft as a function of the parameter of the shaft in the plurality of circumferentially spaced locations; and adjusting a startup sequence or a motoring sequence of the turbomachine based on the magnitude of the deflection.
