This paper presents the design and simulation of an FBG sensor optimized for industrial temperature monitoring applications using COMSOL Multiphysics. The study explores the impact of grating parameters on temperature sensitivity, inculcating Multiphysics simulations to analyze wavelength shifts introduced by thermal variations. Results validate the FBG temperature sensitivity of 13.9467 pm/°C, demonstrating its suitability for precise temperature measurements. Comparative analysis with conventional sensors highlights the advantages of FBG technology in terms of accuracy and robustness. The findings provide valuable insights for optimizing FBG-based temperature monitoring systems in industries such as manufacturing, aerospace, and energy.
