Abstract

PURPOSE: To provide a method for detecting corroded state on wall surface such as on furnace wall, in which a pair of exciters are provided in the direction so that the magnetic field may cancel each other and variation in excited magnetic flux is detected by means of magnetic sensitizer, whereby corroded state on wall surface can be detected correctly at a remote place.
