PROBLEM TO BE SOLVED: To achieve the extension of the life of a measuring detector by preventing the radiation from the gas sump of a pipe stand part for attaching the measuring detector to a duct or the pipe stand part, forming a protective layer comprising a ceramic resin to the contact part with the exhaust gas of the measuring detector and preventing the corrosion of the measuring detector. SOLUTION: In the measuring detector 3 of the exhaust gas attached by insertion to the pipe stand 2 provided to the wall surface of the duct 1 through which the exhaust gas flows, the length L of the pipe stand 2 to which the measuring detector 3 is attached is made as short as possible while the occurrence of the gas sump in the part of the pipe stand 2 and the occurrence of radiation from the part of the pipe stand 2 are prevented. Further, the protective layer 7 comprising the ceramic resin is formed to the contact surface with the exhaust gas of the measuring detector 3. COPYRIGHT: (C)2006,JPO&NCIPI
