Abstract
Disclosed is a sensing system to evaluate and monitor the status of a material forming part of a refractory furnace, integrating an antenna and a grating structure that might be part of the furnace. The system is operative to identify flaws and measure the erosion profile and thickness of different materials, including refractory materials of an industrial furnace, using radiofrequency signals. The system is designed to integrate the antenna with a grating adjacent to an external furnace wall to improve the overall performance of the sensing system as compared to that of the antenna alone during an inspection of the furnace, even in regions of difficult access. Furthermore, the system comprises a mechanism to physically attach the antenna to the furnace grating or to modify the grating configuration around the antenna to improve the system performance for better estimating the remaining operational life and maintenance plan of the furnace.
