Project Description

The project is to develop single-crystal sapphire fiber based sensors for in situ measurement of temperature (up to 1600°C) and dynamic gas pressure in harsh environments. It will also conduct fundamental and applied research that leads to successful single-crystal sapphire fiber hybrid extrinsic/intrinsic Fabry-Perot interferometer (HEIFPI) sensors. A multidisciplinary research team from Missouri University of Science and Technology (MST) and University of Cincinnati (UC) will collaboratively focus on solving the fundamental and engineering challenges. MST and UC will model the HEIFPI sensor in response to temperature and pressure. A fully optimized measurement system integrated with high quality sapphire sensors is the objective.

Project Benefits

This project will develop advanced temperature measuring sensor devices for direct and simultaneous measurement of temperature and dynamic gas pressure in high temperature (up to 1600°C), high pressure, and chemically-harsh environments. The outcome of this technology will be advanced control of key operational parameters resulting in enhanced efficiency, reduced emissions, and improved reliability, availability, and maintainability of existing and next generation power and fuel systems.
