Abstract
A fiber optic monitoring technique for the thickness of furnace wall is demonstrated where conventional monitoring techniques failed because of harsh environments. Based upon OTDR technique, its working principle, structure, and installing manner are introduced. This technique can monitor the thickness wall continuously with an accuracy of 5mm which is enough for the management of operating the furnace.
