Abstract
PURPOSE: To ensure a detection even for a small extent of displacement, by winding a primary coil for energizing directly around a core.
CONSTITUTION: A primary coil 9 for energizing made of heat resistant enamel wire is wound directly around a core 8 fixed to a detector main body 7 or after winding an extremely thin paperlike substance around the core. A secondary coil 11 is wound differentially around the coil 9. In such constitution, even a small extent of displacement can be detected for a material 12 to be examined.
