Optical fiber grating technology

The research field in optical fiber grating technology has opened a new platform for sensor applications (Othonos Kalli 1999). This technique can be used to discriminate different oils as well as to detect adulteration.

The non-invasive requirement for the hot leg temperature sensor must therefore be evaluated against impacts on reactor control response time. Other factors affecting sensor placement include sensor accuracy and resolution, temperature tolerance, sensor size, and feasible attachment methodologies. The sensor technologies under consideration for measuring the hot gas temperature were ultrasonics, thermocouples, resistance temperature deviees (RTDs), optical pyrometry, and fiber Bragg grating.
