Optical Temperature Sensor
An R&D 100 Award winner, measures temperatures from -200 to +600 C, based on temperature-induced shifts in the absorption spectrum of selected materials. With no metallic or conductive components, it is immune to electrical or magnetic interference. Also, it requires no calibration. It is ideally suited for remote, inaccessible and harsh environments; e.g., petrochemical processes, paper mills, nuclear facilities, underground, underwater or in space. (NOTE: a licensee is interested in developing a transmission line temperature monitor that would allow greater loading of lines. They would welcome utility help in determining the benefits and market potential.)
