National Technical Reports Library

The National Technical Information Service acquires, indexes, abstracts, and archives the largest collection of U.S. government-sponsored technical reports in existence. The NTRL offers online, free and open access to these authenticated government technical reports. Technical reports and documents in its repository may be available online for free either from the issuing federal agency, the U.S. Government Publishing Office’s Federal Digital System website, or through search engines.

High Temperature Optical Fiber Thermometer: New instrument measures temperatures to 2000 C.

NTN830224

Publication Date	1983
Page Count	1
Abstract	This citation summarizes a one-page announcement of technology available for utilization. A new high temperature optical fiber thermometer made from a single crystal sapphire has been developed. The instrument will permit scientists and engineers to measure temperatures to 2000 C--an increase of 500 C above the maximum operating temperature of the present thermocouple standard. The new device has the potential to be 10 times more accurate than the existing standard. In gas streams, the optical fiber thermometer responds eight times faster than conventional measurement techniques. The device also has lower heat transfer losses and therefore can measure temperatures at lower gas stream velocities. It should prove useful for measurement and control of high temperatures in gas turbines and internal combustion engines, as well as in chemical processes. Other possible uses of the optical fiber thermometer are for power generation equipment, nuclear energy systems, weapons, space applications and similar areas. Measurements made with this thermometer are free from the interference effects caused by strong nuclear and electromagnetic radiation fields. ...FOR ADDITIONAL INFORMATION: Contact: Mr. Roger Rensberger, National Bureau of Standards, Washington, DC 20234; (301) 921-3181.
