The objective of the work reported in this paper is to reduce the effect of electrical runout in order to improve accuracy of eddy current probe sensing of turbomachinery vibration. Results of a combined analytical study and test program indicate that electrical runout effect can be reduced by configuration changes such as probe coil diameter, operating air gap, and operating frequency.
