PURPOSE:To prevent the inflow of a high temp. gas into a heat insulating material and to measure the temp. of the gas accurately by inserting a temp. sensitive element into a protecting cylinder via the heat insulating material. CONSTITUTION:The root part of a well 9 is secured airtightly into the opening pierced in a liner pipe 2 and its leading end projects into the pipe 2. A protecting cylinder 7 is secured airtightly to a pressure resistant pipe 5, and extends by penetrating through a heat insulating material 1. A temp. sensitive element 4 is inserted via a heat insulating material 8 into the cylinder 7, and the leading end thereof is inserted into the leading end part of the well 9. As a result, the inflow of high temp. fluid into the heat insulating material is prevented and the temp. of the gas is measured accurately. |
