SHORT COURSE ON RADIATION THERMOMETER MEASUREMENT OFFERED.Infrared radiometry Radiometry A branch of science that deals with the measurement or detection of radiant electromagnetic energy. Radiometry is divided according to regions of the spectrum in which the same experimental techniques can be used. is widely used in science and industry to measure temperature, particularly when a contact measurement would be hazardous or impossible. Practical applications span a broad range of industries, including the inspection of high-voltage power-line splices, computer circuit boards, jet engines, industrial processes, food-safety equipment and building insulation Thermal insulation in buildings is an important factor to achieving thermal comfort for its occupants. Insulation reduces unwanted heat loss or gain and can decrease the energy demands of heating and cooling systems. systems. While radiation thermometry thermometry Science of measuring the temperature of a system or the ability of a system to transfer heat to another system. Temperature measurement is important to a wide range of activities, including manufacturing, scientific research, and medicine. is widely used, the factors that go into making accurate, reliable measurements are not always well understood by users. To help scientists, engineers and calibration technicians better understand and control their radiation thermometer measurements, NIST (National Institute of Standards & Technology, Washington, DC, www.nist.gov) The standards-defining agency of the U.S. government, formerly the National Bureau of Standards. It is one of three agencies that fall under the Technology Administration (www.technology. has developed a 4 day course on temperature measurement by radiation thermometry. It covers the fundamentals of determining temperatures from thermal radiation thermal radiation Process by which energy is emitted by a warm surface. The energy is electromagnetic radiation and so travels at the speed of light and does not require a medium to carry it. ; provides practical experiences in using radiometers, sources and optical elements; and trains participants in performing uncertainty analysis. It includes skill-building, problem-solving laboratory experiments and lectures on radiometry fundamentals, emissivity Emissivity The ratio of the radiation intensity of a nonblack body to the radiation intensity of a blackbody. This ratio, which is usually designated by the Greek letter ε, is always less than or just equal to one. , blackbodies, the signal measurement equation, the temperature measurement equation and NIST temperature calibration services. Up to 16 participants can take the annual course. The short course is offered annually.
