This book was released on 1998-09-01 with total page 214 pages. Available in PDF, EPUB and Kindle. Book excerpt: Volume 2 of the Handbook of Temperature Measurement, prepared by the CSIRO National Measurement Laboratory, Australia, discusses the operation, calibration and usage of resistance and liquid-in-glass thermometers. Both standard-platinum-resistance thermometers and industrial-resistance thermometers are examined, and details on a variety of resistance-measuring techniques are given. Also included is a final version of the official text of the International Temperature Scale 1990 (ITS-90). The authors of this volume are John J. Connolly and E. Corina Horrigan.

Book excerpt: The monograph describes the methods and equipment employed at the National Bureau of Standards for calibrating standard platinum resistance thermometers (SPRT) on the International Practical Temperature Scale (IPTS-68).The official text of the scale is clarified and characteristics of the scale are described.Several designs of SPRT's are shown and discussed in the light of the requirements and recommendations on the text of the IPTS-68.Possible sources of error such as those due to the internal and external self-heating effects and the immersion characteristics of SPRT's are described in detail.Precautions and limitations for the mechanical and thermal treatment and for the shipment of SPRT's are indicated, and a guide is given for those desiring the thermometer calibration services of NBS.(Modified author abstract).

Available in PDF, EPUB and Kindle. Book excerpt: Cryogenics, a term commonly used to refer to very low temperatures, had its beginning in the latter half of the last century when man learned, for the first time, how to cool objects to a temperature lower than had ever existed na tu rally on the face of the earth. The air we breathe was first liquefied in 1883 by a Polish scientist named Olszewski. Ten years later he and a British scientist, Sir James Dewar, liquefied hydrogen. Helium, the last of the so-caBed permanent gases, was finally liquefied by the Dutch physicist Kamerlingh Onnes in 1908. Thus, by the beginning of the twentieth century the door had been opened to astrange new world of experimentation in which aB substances, except liquid helium, are solids and where the absolute temperature is only a few microdegrees away. However, the point on the temperature scale at which refrigeration in the ordinary sense of the term ends and cryogenics begins has ne ver been weB defined. Most workers in the field have chosen to restrict cryogenics to a tem perature range below -150°C (123 K). This is a reasonable dividing line since the normal boiling points of the more permanent gases, such as helium, hydrogen, neon, nitrogen, oxygen, and air, lie below this temperature, while the more common refrigerants have boiling points that are above this temperature. Cryogenic engineering is concerned with the design and development of low-temperature systems and components.
Download or read book Temperature written by T. J. Quinn and published by Academic Press. This book was released on 2013-10-22 with total page 508 pages. Available in PDF, EPUB and Kindle. Book excerpt: Temperature, Second Edition gives a comprehensive account of the principles of thermometry over the range 0.5 K to about 3000 K. The book focuses on various topics on the field of thermometry such as the full description of the ITS-90, its practical application and preparation; accounts of total radiation thermometry and acoustic gas thermometry using spherical resonators; and the development of sealed cells for the realization of fixed points. The construction and use of high-temperature platinum resistance thermometers; introduction of the use of gold-platinum thermocouple; and the calibration and practical application of radiation thermometers are discussed as well. Physicists, engineers, researchers, and students will find the book a good reference.

Available in PDF, EPUB and Kindle. Book excerpt: Comprehensive coverage of superconductivity from the Wiley Encyclopedia of Electrical and Electronics Engineering Engineering Superconductivity features fifty articles selected from the Wiley Encyclopedia of Electrical and Electronics Engineering, the one truly indispensable reference for electrical engineers. Superconductor technology has made highly advanced experiments possible in chemistry, biochemistry, particle physics, and health sciences, and introduced new applications currently in use in fields from medicine to cellular communications. Taken together, these articles-written by acknowledged experts in the field-provide the most complete and in-depth accounting of superconductivity in existence. The book brings together a wealth of information that would not be available to those who do not have access to the full 24-volume encyclopedia. This thorough survey looks at the application of superconductors from an engineer's practical perspective rather than a theoretical approach. Engineering Superconductivity provides full coverage of the fundamentals of superconducting behavior and explains the properties and fabrication methods of commercially produced superconductors. Up-to-date material on superconductor applications as well as competing technologies is included. The fifty articles presented here are divided into three sections: Superconductivity and magnetism Superconductors Applications and related technology Engineering Superconductivity is a complete and up-to-date reference for engineers, physicists, chemists, materials scientists, and anyone working with superconductors.

Available in PDF, EPUB and Kindle. Book excerpt: The Standard Platinum Resistance Thermometer (SPRT) is defined by the International Temperature Scale of 1990 (ITS-90) as the interpolating instrument for temperatures between 13.8033 K and 1234.93 K. This SRM concerns the calibration characteristics of a group of 20 capsule-type SPRTs within the range of temperatures between 13.8033 K and 429.7485 K. The platinum wire used for the construction of the resistor elements of this SRM was derived from platinum bar stock with a chemical purity of 99.999 % by weight. Each of the 20 units has been evaluated, certified, and calibrated according to the definitions of the ITS-90. The resistance characteristics of all 20 units have been measured at 11 fixed point temperatures from 4.22 K to 429.7485 K as well as at least 7 other intermediate points. The procedures used in performing the calibrations and the supplemental measurements are documented in this publication. The resulting analysis pertaining to each individual unit, as well as the SRM sample population as a whole, is presented in detail.
