A DEVICE FOR MEASURING GAS TEMPERATURE WITH RADIATION INTERFERENCE COMPENSATION AND THE MEASUREMENT METHOD

摘要

A gas thermoscope capable of radiation interference compensation and a method for measuring gas temperature are provided to compensate radiation loss without a separate port and improve the accuracy of measured gas temperature. A gas thermoscope comprises: a hollow cylindrical housing whose top and bottom are opened; a sealing member fitting inside the housing; a hollow cylindrical housing tube(30); a pair of thermocouples(10,20) formed in the housing tube; and a cover screwed up with the upper end exterior wall of the housing. The diameter of a pair of thermocouples is different. Each thermocouple comprises: a ceramic rod(12) for a thermocouple sensor in which the two metals of the different kind are welded inside; and a thermocouple guide tube(11) surrounding the exterior wall of the ceramic rod. The cover is formed on the top of the housing.
