About this technology
Overview
Accurate and reliable pressure data is fundamental for monitoring engine health for the safe and efficient operation of high performance engines. Innovators at NASA's Glenn Research Center have developed a single pressure and temperature sensor system that provides in-situ data in harsh operating environments like combustion. Although current SiC pressure sensors can operate at 800°C inside combustion chambers, the output response is sensitive to temperature changes and requires temperature compensation schemes that rely on a second separate temperature sensor to get a true measure of pressure. The new NASA pressure/temperature (P/T) sensor chip enables real-time translation of pressure and uses only a single tap for two engine measurements. This important sensor system and packaging can provide more accurate data for combustion simulations and to monitor engine health to improve performance and extend the service lifetime of commercial and military aircraft, automotive engines, and power plants.
