摘要： PROBLEM TO BE SOLVED: To reduce occurrence of electric noise and to provide signal output of high detection sensitivity and stability by providing a cylindrical ferrite or a metal and allowing slide in accordance with deformation of inner diameter of a heat transfer tube. SOLUTION: A sensor holder 1 is, at always, pressed to the inside surface of a heat transfer tube by a spring 7, and due to deformation of a heat transfer tube 9, a holder 1 moves in the direction of arrow. When the spring 7 is pressed, a circular ferrite group or metal 5 fixed to the holder 1 moves downward, thus, an impedance of a displacement detection coil 4 changes. Since the coil 4 is a bridge circuit, the impedance change of the coil 4 is outputted as a voltage or current change. The signal output goes through a displacement measuring device 19, then signal-processed at a signal processing device 20, and a deformation amount is displaced on a display device 21, while it is recorded with a recording device 22.

摘要： PURPOSE:To detect a defective part, where the inner surface of a long pipe is thick or the diameter is small by the attachment of a foreign matter on the inner surface. CONSTITUTION:A material to be detected 5, which is slightly smaller than the inner diameter of a long pipe 1, is inputted into a long pipe 1, which is sent into the longitudinal direction. When the diameter of the inner surface of the long pipe is not contracted and excellent, the material to be detected 5 is stopped at the specified part. When a defective part 4 wherein the inner surface of the long pipe 1 is thick or the diameter is contracted by the attachment of foreign matter, arrives there the material to be detected 5 is pushed by the defective part 4 and moved. The defective part of the long pipe 1 is detected by detecting the fact that the material to be detected 5 is moved. The material to be detected 5 can be made to be a sphere or a cylindrical body made of metal, and the moved material to be detected 5 can be detected with a metal detector 11.
