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.
Program Background and 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.
Researchers met their initial milestone of constructing models of the HEIFPI sensor in response to anticipated temperature and pressure conditions. Researchers then established structural parameters of the HEIFPI sensor to guide device fabrication. The team has completed a unique sensor fabrication device using a femtosecond laser. Using this device, the team has been able to micro machine sapphire for the purposes of temperature and pressure measurement. In addition, the team has made progress on formulations of thin ceramic films to coat the sapphire. The research team also participated in sensor design and packaging for in situ monitoring of high-temperature synthesis gas in a small-scale coal gasifier at the University of Cincinnati. The experience of testing in harsh environment benefits the research on sensors that are viable for commercial applications.
