Hight Temperature Strain Gauges
A real-world story of NASA technology finding a life beyond the mission.
About this technology
Overview
Technology developed by NASA's Dryden Flight Research Center was incorporated into new high-temperature strain gages produced by Hitec Corporation. Technology provides method of compensating for erroneous strain measurements caused by expansion of metals at high temperatures. The Dryden system developed under contract by Boeing Company cancels out heat expansion strain so only stress induced strain is measured by the sensor. Hitec obtained a license to use the NASA/Boeing technology in its new gages whose principal use is in power plants and refineries for monitoring stress in boilers and pipes.
