Abstract

PURPOSE:To make the discrete monitoring of places where abnormality occurs systematically possible by opening a hole in the external conductor near the connected part of coaxial feeders and taking the light signal corresponding to the temp. change of internal conductors to the outside. CONSTITUTION:The external conductors 1 and 2 of coaxial feeders are electrically and mechanically connected by means of flanges 5, 6 provided with an O-ring 8 for assuring air tightness. On the other hand, internal conductors 3, 4 are electrically and mechanically connected by means of a connector 7 held by an insulator 9. When a hole 10 is opened in the external conductor 1 near this connected part and an infrared light detector 11 is provided on the outer side of the hole 10, the quantity of infrared light corresponding to the temp. of the internal conductor is detected and the temp. of the coaxial feeders is surely detected. Hence, the discrete monitoring of places of the coaxial feeders for broadcasting or the like where abnormality occurs systematically.
