Evolution of Gas Sensors: Beatrice Hicks creates device to measure gas in critical industrial applications
Inventor, Beatrice Hicks, is both a 2017 inductee into the National Inventors Hall of Fame as well as one of America’s truly trailblazing women engineers, one of the first to enter the field of technological development in the mid-20th century. Hicks would go on to become instrumental in the founding of the Society of Women Engineers and her story is a wonderful reminder of the power of both a good education and the ability to believe in one’s self… Hicks’ major innovation in gas sensor tech is outlined by U.S. Patent No. 3046369, titled Device for Sensing Gas Density and issued July 24th, 1962. It claimed, in a density system, a chamber containing gas, a hollow case with an interior cavity in communication with the chamber, a sealed expansible and contractible bellows mounted within the hollow case and in communication with gas contained in the chamber, and an actuating portion to actuate an output means when the bellows moves to a critical position in response to the pressure-versus-temperature function of the gas.
