Pyrometry: A Practical Treatise on the Measurement of High Temperatures is a comprehensive and authoritative work dedicated to the science and practice of measuring high temperatures, a field known as pyrometry. Authored by Charles R. Darling, this book delves deeply into the principles, methods, and instruments used in the accurate determination of temperatures far beyond the reach of ordinary thermometers. The treatise begins with a historical overview of temperature measurement, tracing the evolution of pyrometric techniques and the development of various devices. It then systematically explores the physical principles underlying temperature measurement, including the behavior of materials at elevated temperatures, the laws of radiation, and the calibration of instruments. The book provides detailed descriptions of the different types of pyrometers, such as expansion pyrometers, electrical resistance pyrometers, thermoelectric pyrometers, and optical pyrometers. Each instrument is examined in terms of its construction, operation, advantages, limitations, and practical applications in industries such as metallurgy, ceramics, glassmaking, and chemical manufacturing. The author emphasizes the importance of accuracy, reliability, and proper calibration, offering practical advice and experimental data to guide users in selecting and maintaining pyrometric equipment. In addition to technical discussions, Pyrometry includes numerous illustrations, diagrams, and tables that clarify complex concepts and assist readers in understanding the intricacies of high-temperature measurement. The book also addresses common sources of error, methods for correcting inaccuracies, and the interpretation of results. Written in a clear and accessible style, this treatise serves as both a reference and a practical manual for engineers, scientists, and students involved in high-temperature processes. With its thorough coverage and practical insights, Pyrometry: A Practical Treatise on the Measurement of High Temperatures remains a valuable resource for anyone seeking to master the art and science of pyrometry.
