Abstract :
This paper describes a novel five-coil eddy current probe with the capability of simultaneous multi-function sensing, suitable for automated manufacturing and sensing. The probe consists of a single drive coil with two pairs of smaller pickup coils. Multiple sensing functions are realized by reading the pickup coils in different combinations of operation, and experimental results are given for position and angle sensing of shallow steps on a metal surface.
