Title: High-temperature fiber optic cubic-zirconia pressure sensor - article no. 124402

Abstract

There is a critical need for pressure sensors that can operate reliably at high temperatures in many industrial segments such as in the combustion section of gas turbine engines for both transportation and power generation, coal gasifiers, coal fired boilers, etc. Optical-based sensors are particularly attractive for the measurement of a wide variety of physical and chemical parameters in high-temperature and high-pressure industrial environments due to their small size and immunity to electromagnetic interference. A fiber optic pressure sensor utilizing single-crystal cubic zirconia as the sensing element is reported. The pressure response of this sensor has been measured at temperatures up to 1000{sup o}C. Additional experimental results show that cubic zirconia could be used for pressure sensing at temperatures over 1000{sup o}C. This study demonstrates the feasibility of using a novel cubic-zirconia sensor for pressure measurement at high temperatures.
