  1. 6H-SiC Pressure Sensors for High Temperature Applications Small Business Innovation Research Kulite Semiconductor Products, Inc. Leonia, NJ INNOVATION A silicon carbide (SiC) pressure sensor for use at temperatures as high as 500C, which is approximately 100C higher than can be withstood by presently available silicon pressure sensors • ACCOMPLISHMENTS • Prototype SiC pressure sensors were developed in Phase II contract • The pressure sensors were shown to be capable of operating at 500C for several hours • Provided GRC with prototype SiC pressure sensors • COMMERCIALIZATION • A high temperature pressure sensor for engine aircraft development and test. Fast response pressure measurements in the compressor hot section for stall detection and control • This pressure sensor can be used for other high temperature turbine engine applications SiC Sensor Mounted on a Header • GOVERNMENT/SCIENCE APPLICATIONS • Phase III of $500K to provide GRC with 6-10 prototype SiC pressure sensors. Funding provided by Advanced High Temperature Engine Material Technology Program (HITEMP) and Higher Operating Temperature Propulsion Components (HOTPC) Program. • A prototype SiC pressure sensor was successfully tested at Honeywell in Phoenix, AZ in September 2000. Additional testing is planned at Pratt & Whitney in 2001. • For use in military aircraft and any other turbine engine, e.g., tanks Glenn Research Center Instrumentation 3-046 1991 Phase II, NAS3-27011, rev. 5/01 NASA Contact – Glenn Beheim Company Contact – Alex Ned 53
