Pressure measurement in ultra high temperature is very important in a wide array of industries. Optical fiber-based sensing instrumentation is particularly attractive for the measurement of a wide variety of physical and chemical parameters due to their inherent characteristic. Conventional quartz glass fiber-optic sensors show excellent performance in pressure measurement, applications, but they cannot be used for contact measurement at temperatures above 800 °C. Single-crystal sapphire has been extensively used for high temperature measurement over 1000 °C, but very little data was reported for pressure measurement. In order to extend the operating temperature of fiber-optic pressure sensors, a fiber optic pressure sensor utilizing single crystal cubic zirconia as a structure material has been developed. The pressure response of the sensor has been measured from 0 to 1700Psi. Additional experimental results from 23 °C to 1026 °C show that cubic zirconia could be used for pressure sensor at temperatures over 1000°C. This study demonstrated the general functionality of the single crystal cubic zirconia sensor for pressure measurement at high temperatures.
