Abstract

PURPOSE:To realize high detection sensitivity by using a cable formed by forming 1 line around a cable for detecting the abnormal temperature of piping, etc., by using an amorphous magnetic material having a prescribed Curie temperature and then by covering the amorphous material with an insulating material. CONSTITUTION:A temperature detecting element used for a detector for detecting the abnormal temperature of long piping, a tank, etc., or the leakage of a hot fluid and its position is made by covering a beltlike amorphous magnetic material 11 with an insulator 13 of polyethylene, etc., and then by winding a conductor 12. Further, the element 2 is wound with an insulating tape 14. Consequently, variations in characteristic impedance due to variations in temperature approximately at a Curie temperature are increased and the level of a reflected pulse signal at an abnormal temperature position rises, thereby improving detection sensitivity greatly. In addition, the process of manufacturing is simplified and the cost is reduced.
