Sinopsis
Excerpt from Practical Pyrometry: The Theory, Calibration, and Use of Instruments for the Measurement of High Temperatures
The day is already past when foundrymen and steel workers de pend upon the eye to judge the temperatures of their product in the various stages of its heat treatment, when makers of ceramic products depend upon the indication of fusible cones, and When Operators of cold storage plants are content to Observe numerous thermometers scattered throughout their establishments. The requirements of modern industrial processes and the severe com petition of commercial enterprises now require not only more precise knowledge of temperatures, but in many cases also re quire a continuous automatic record of the temperature state extending over an interval of time.
Several years ago, anticipating the need by technical students of a Course in High Temperature Measurements, the work of testing the various methods and apparatus was begun. After three years devoted to this survey, a course was organized and Offered. It was received with such favor that it was made a required subject in the plan of study for students of chemical engineering at Purdue University. Each year since then, a new edition of Notes, in mimeographed form, has been put into the hands of the students. It has now been thought proper to put into more readable and permanent form the results of this experience.

PRACTICAL PYROMETRY
CHAPTER I STANDARD TEMPERATURE SCALES
1. The Comparison of Temperatures. - Lengths can be directly measured by means of a foot rule, a meter bar, a surveyor's chain or other standard of length. Similarly, volumes can be measured in terms of some standard of volume such as a gallon, bushel, or cubic foot. Temperatures, however, cannot be directly measured. In fact, temperatures can be compared only indirectly in terms of some property which changes in magnitude when temperature changes. For example, since when under constant pressure the length and volume of most substances increase as their temperature increases, changes of length and volume can be used for the comparison of temperatures.
Again, since the pressure of a fixed mass of gas kept at constant volume increases when the temperature of the gas is raised, changes in the pressure of a gas under these conditions can be used as a measure of the changes of temperature.

Practical Pyrometry: The Theory, Calibration (Classic Reprint)
Impresión bajo demandaLibrería: Forgotten Books, London, Reino Unido
Calificación del vendedor: 5 de 5 estrellas
Paperback. Condición: New. Print on Demand. This book provides a comprehensive guide to temperature measurement using resistance pyrometry, thermoelectric pyrometry, and radiation pyrometry. The author, an expert in the field, presents a historical and theoretical context for each method, tracing their development and explaining the underlying principles. The book covers both the advantages and limitations of each technique, discussing their suitability for different applications and the challenges encountered when measuring extremely high or low temperatures. The author also delves into the thematic depth of temperature measurement, exploring the relationship between temperature and energy, the concept of black-body radiation, and the challenges of obtaining accurate measurements in industrial settings. Through its detailed explanations and practical insights, this book serves as an invaluable resource for engineers, scientists, and technicians seeking to enhance their understanding and application of temperature measurement techniques. This book is a reproduction of an important historical work, digitally reconstructed using state-of-the-art technology to preserve the original format.
