Abstract
A system () for measuring the gap () between a rotating blade () and a stationary component () of a turbo-machine, including an eddy current coil () and an eddy current tester (). The eddy current tester may excite the coil in a pulsed eddy current testing mode. The coil is positioned in a stationary portion () of a turbo-machine traversed by a rotating blade and the eddy current tester is coupled to the eddy current coil to provide an indication responsive to a distance between the blade and the stationary portion as the blade traverses the position. The coil may be mounted in a frangible ceramic pill () movably disposed in a housing (). The coil is positioned near the turbine blade, the coil is excited with a voltage step function (), and the response () of the coil to the step function is detected and processed to determine the proximity of the blade.
