This book describes the practice of radiation thermometry, both at a primary level and for a variety of applications, such as in the materials processing industries and remote sensing. This book is written for those who will a) apply radiation thermometry in industrial practice b) use radiation thermometers for scientific research, c) the radiation thermometry specialist in a national measurement institute d) developers of radiation thermometers who are working to innovate products for instrument manufacturers and e) developers non-contact thermometry methods to address challenging thermometry problems. The author(s) of each chapter were chosen from a group of international scientists who are experts in the field and specialist(s) on the subject matter covered in the chapter. A large number of references are included at the end of each chapter as a resource for those seeking a deeper or more detailed understanding. This book is more than a practice guide. Readers will gain in-depth knowledge in: (1) the proper selection of the type of thermometer; (2) the best practice in using the radiation thermometers; (3) awareness of the error sources and subsequent appropriate procedure to reduce the overall uncertainty; and (4) understanding of the calibration chain and its current limitations. Coverage of all fundamental aspects of the radiometric measurements Coverage of practical applications with details on the instrumentation, calibration, and error sources Authors are from the national labs internationally leading in R&D in temperature measurements Comprehensive coverage with large number of references

Authored by two highly respected experts in this specialist area, The Fundamentals of Radiation Thermometers is an essential resource for anyone intending to measure the temperature of an object using the radiated energy from that object. This readable, user-friendly book gives important background knowledge for anyone working in the field of non-contact thermometry. The book begins with an accessible account of how temperature scales are set up and defined, and explores the historic development of temperature scales and Planck’s radiation law. Through explaining the reliability of both emissivity values and extrapolation to different wavelengths and temperatures, the book provides a foundation for understanding when a valid measurement with realistic uncertainties has been made, or if an inappropriate emissivity value has been used with consequent unknown errors. The book also presents the hardware of radiation thermometers, allowing the reader to specify an appropriate design for a particular measurement problem. It explores multi-wavelength radiation thermometry and its associated pitfalls, and a final chapter suggests strategies to minimise the uncertainties from unreliable emissivity data.

This report covers work performed on Contract AT(30-1)-1316 between the Brown Instruments Division of the Minneapolis-Honeywell Regulator Company and the New York Operations Office of the Atomic Energy Commission. The emittance of salt-coated uranium (a eutectic mixture of lithium and potassium carbonates) was found to be about 0.86 between the temperatures of 900 deg F and 1200 deg F. The emittance of uranium oxide (U3O8) was found to be about 0.82; the emittance of the salt mixture was 0.9; and the emissivity of uranium metal between 200 deg F and 600 deg F was 0.15. A holder and housing for the Brown Miniature Radiamatic Radiation Pyrometer was developed which was flexible and could be used to advantage measuring the temperature of uranium ingots and bars during the rolling operation. A number of these units were fabricated for the Feed Materials Center at Fernald, Ohio. A calibration panel was designed and built which permitted easy calibration of the Radiamatic assemblies. This panel contained a blackbody furnace as a radiation reference source. A considerable amount of time was spent during the spring of 1952 working at the experimental rollings held at several steel mills.

In most field applications, broadband measurements are used where the spectral product of the source distribution and the meter’s spectral responsivity is measured. This book discusses detector-based radiometric, photometric, color, radiation-temperature, digital imaging-system, and LED measurements. It also shows that, while in photometry, the meter’s standard response covers only the visible, broadband measurements in the UV and IR require different standards. To avoid large errors when using a traditional detector- or source-standard, where the differences in the source distributions and in the meter’s responsivities produce large errors, the signal measurement procedure itself must be standardized. To satisfy the steps of the procedure, selected or properly designed meters should be used. This book is a guide to performing uniform broadband measurements with low uncertainty.
