Paperback. Condición: New. Print on Demand. This book delves into the topic of pyrometer glassesâ"a type of color screen crucial to the functioning of optical pyrometers used for measuring extremely high temperatures. The author emphasizes the importance of the effective wavelength of pyrometer glass in determining the accuracy of temperature measurements. Contrary to previous assumptions, the author posits that the effective wavelength of these glasses shifts with the temperature of the source being observed. This discovery leads to a new understanding of the factors that can introduce errors in temperature measurements made using optical pyrometers equipped with pyrometer glasses. The author provides a detailed analysis of the relationship between the effective wavelength and the temperature of the source, discussing the implications for the calibration and use of these instruments. The book offers valuable insights for scientists and researchers working in the field of temperature measurement and serves as a valuable resource for anyone interested in the theory and application of optical pyrometers. This book is a reproduction of an important historical work, digitally reconstructed using state-of-the-art technology to preserve the original format.

Paperback. Condición: New. Print on Demand. This book lists the potentials required to excite successive types of radiation in gases and vapors by electron impact, measured by observing the photoelectric effect of the arc radiation on other electrodes within the same tube. The range of potentials ranges from 17 to 500 volts. The author measured critical radiating potentials for 11 gases and vapors and identified the L series limits of sodium, magnesium, phosphorus, sulphur, and chlorine. Additionally, the K series limits of carbon, nitrogen, and oxygen are identified, as well as the softest X -ray limits (M series) of potassium.

Paperback. Condición: New. Print on Demand. This book details the methods previously applied by the author to the study of critical potentials in metallic vapors, with some modifications, to the nonmetallic elements phosphorus, iodine, and sulfur, as well as nitrogen, oxygen, and hydrogen. The phenomena of electron currents in polyatomic, nonmetallic elements can be best introduced through a statement of the essential features of electron impacts with metallic vapors, since work with these has yielded results of considerable accuracy and of definite theoretical significance. Collisions of low-speed electrons with metallic molecules are elastic, but with higher speeds two types of inelastic impact occur. When the velocity in volts is greater than the resonance potential, collisions are inelastic and the velocity lost at collision is equal to the resonance potential. When the velocity of the colliding electron is greater than the ionization potential, the molecule is ionized and the energy lost by the electron is expended in removing an electron from the molecule. The author found two resonance potentials in some of the vapors and concludes that this is a characteristic property of metals of Group II in the periodic table.

Paperback. Condición: New. Print on Demand. This book explores the construction and use of radiation pyrometers, instruments designed to measure high temperatures. The author begins by outlining the principles behind radiation pyrometry, including the Stefan-Boltzmann equation, which forms the basis for these devices. Detailed chapters describe the construction and calibration of various radiation pyrometer types, including mirror and thermocouple, lens and thermocouple, and cone thermoelectric pyrometers. The author also covers the application of radiation pyrometers in various industrial and scientific fields, as well as sources of error and methods to minimize their impact on measurements. In-depth discussions on the influence of the pyrometer's construction and geometry, the characteristics of the radiating source, and the intervening medium provide valuable insights for practitioners seeking to obtain accurate temperature readings.
