Abstract
A new method for measuring radial and axial displacements of complex-shaped blade tips with the help of a distributed cluster of two single-coil eddy-current sensors with sensitive elements made as conductor strips is described. The main distinctive features of the method and the results of an experimental analysis of families of calibration characteristics of both sensors are considered. This analysis proves a higher sensitivity to changes in radial displacements and an extended range of axial displacement measurements of the new method as compared to the existent one.
