PROBLEM TO BE SOLVED: To measure the temperature in a furnace with higher accuracy and better responsiveness than hitherto by preventing flow-in of back draft, in a large-scale furnace comprising a shell and a refractory body such as an air-heating furnace. SOLUTION: This temperature measuring device is equipped with a temperature measuring body 6a for measuring the temperature of the refractory body 4 by bringing a temperature measuring body tip part 60 close to a spot whose temperature is to be measured on the refractory body 4, a pad part 6b for conducting the heat on the spot whose temperature is to be measured to the temperature measuring body tip part 60 adherently to the spot whose temperature is to be measured, a pressure contact part 17 for pressure-contacting the pad part 60 onto the spot whose temperature is to be measured by pressing the temperature measuring body 6a and the pad part 6b onto the spot whose temperature is to be measured from the outside of a furnace body, and a furnace wall fixing part 14 for fixing the temperature measuring body 6a and the pressure contact part 17 to a furnace body outer cover 1. The temperature measuring body tip part 60 can be deformed in a direction orthogonal to the axial direction. COPYRIGHT: (C)2009,JPO&INPIT
