Performance Investigation of Fiber Bragg Grating Temperature Sensor for Industrial Application

Abstract

Monitoring the temperature in industrial applications is a crucial factor which decides the stability of the system. In high temperature industrial applications conventional sensors have not proved to be beneficial due to their malfunction around 150 degree Celsius temperature. These conventional sensors are replaced by the Fiber Bragg Grating FBG sensors due to their inherent features of EMI immunity, compact size and light in weight. In this research, we propose a model which use FBG sensor to measure temperature for industrial applications. The maximum temperature that can be sensed by this proposed sensor model is up to 900 degree Celsius and the system is stable. In this research relation between wavelength and temperature is considered and result shows FBG sensor has high sensitivity than conventional sensors. If temperature goes beyond that a particular range it will affect the stability. Some systems work for a particular temperature range and some of the system work at high temperature range. High temperature value can be detected by the sensor which can be done through optimizing the dimension of the design. In this research we have also present the result which shows how much temperature gets affect due to change in the dimension of the design. This research can be used where high temperature accurate monitoring and sensing is required. In this research work optimization of design model is also done on the basis of its dimensions
