APPARATUS FOR MONITORING DAMAGE OF PIPE

摘要

An apparatus for monitoring damage of pipe according to an exemplary embodiment of the present invention includes an electric power supply, a core which is formed long in a lengthy direction of a pipe and contacts the outer wall of the pipe, a coil which is wound around the outer circumferential surface of the core, an electric current detector which traces the electric current which flows in the coil and detects a magnetic saturation electric current when the second magnetic saturation state has been formed, and a comparator.
