Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from High-Temperature Measurements The measurement Of high temperatures was considered for a long time to be a very difficult operation and Of a very uncertain precision. There were cited with admira tion a half-dozen determinations seeming to merit some confidence. During the last few years the question has made considerable progress, and we possess to-day several sufficiently precise pyrometers whose usage is rapidly spreading among scientific and industrial laboratories. Before describing them, perhaps it will not be useless to indicate the services that they may render to science and to industry, by giving a brief summary Of similar services that they have already rendered.

This book was released on 2018-09-23 with total page 76 pages. Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from High Temperature Measurement by Electric Means The accurate measurement of high temperatures has come to be a very essential feature of many industrial pro cesses. The pyrometer makes it possible to reproduce with precision any temperature that has been found to yield the best results in Operations requiring careful heat treatment. In the making of tinted glass, for example, the preper regu lation of the temperature of the furnace is necessary to pre vent burning out the color. Instead of depending upon the workman to judge of the condition of the material with his eye, the manufacturer gives instructions to maintain the heat at a certain temperature, knowing then that the output will be of a certain uniform grade. In this manner the variable human element is eliminated and waste prevented. The temper ing of tools, the burning of ceramic products, the Operation of gas producers, the manufacture of iron and steel and the annealing of castings are a few examples of processes that may be carried on to better advantage with the aid of refined methods of measuring high temperatures. The recording pyro meter is rapidly coming into use as an efficient means of eu pervising processes requiring heat treatment.

Download or read book The Measurement of Steady and Fluctuating Temperatures Classic Reprint written by R. Royds and published by . This book was released on 2015-09-27 with total page 252 pages. Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from The Measurement of Steady and Fluctuating Temperatures This book is intended to give a concise account of modern methods of measuring both steady and fluctuating temperatures and to indicate their applications in industrial practice. Until recently the mercury thermometer provided the only important method of measuring temperatures in which most engineers could place any degree of confidence. But the need of some reliable means of measuring high temperatures beyond the range of ordinary thermometers led physicists to experiment with and to perfect other methods, in particular the thermo-couple and platinum resistance thermometers or pyrometers, and also radiation and optical pyrometers. In their hands these methods became so reliable under skilful operation that, with the increasing technical skill of engineers and metallurgists, their use has extended rapidly in industrial practice as a means of measuring or controlling the temperatures of gases, furnaces, solid and molten metals, etc. In some cases they have replaced the more or less haphazard method of guessing these temperatures by appearances, and their use in this direction is rapidly extending. In other cases, particularly in certain metallurgical operations, the temperatures need to be regulated so closely that a reliable means of measuring the temperatures makes all the difference between success and failure. Again, mercury thermometers are of little use in measuring the temperature of a thin metal wall or in following any rapidly fluctuating temperature with reasonable accuracy, and such measurements were only possible when the present methods became available. The accurate measurement of temperature is also important in problems associated with the transmission of heat.

This book was released on 2018-02-15 with total page 24 pages. Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from An Evaluation of Dial Thermometers for Measuring Soil Temperature The thermistor used is designated by the manufacturer as model No. 7a disc type thermistor and is the same unit used in the Colman fiber glass soil-moisture element. It is a pellet of metal oxide, silver coated on its opposing sides, inches in diameter and inches thick. The manufacturer's rated resistance is ohms, plus or minus 10 percent at 25 degrees centigrade The resistance of the pellet is sensitive to changes in temperature. Consequently, it can be used to determine-temperature. Each of the two types of thermometers was installed, in duplicate, at h and 8 inch depths in Cecil clay loam soil, covered with a Bermuda grass sod. They were installed in a rectangular block such that there were four of one type in line, spaced about one foot apart, with the first and third thermometer being at the h-inch depth and the second and fourthat the 8 inch depth. This pattern was repeated for the second type with the line of thermometers placed about one foot from the first type and parallel to them. This installation resulted in the two types and depths being equidistant from each other. The dial type thermometers were installed by forcing the stem into the ground to the desired depth. Soil temperatures were read directly in degrees Fahrenheit from the dial scale without disturb ing the thermometers. A point 1 inch from the bottom of the stem was taken as the reference for depth. The 8 inch thermometer was therefore sunken into the surface by'l inch. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.

Download or read book Pyrometry written by Chas R. Darling and published by Forgotten Books. This book was released on 2018-03-02 with total page 272 pages. Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Pyrometry: A Practical Treatise on the Measurement of High Temperatures The next step in advance was the introduction of the expansion pyrometer by John Daniel] in 1822. The elongation Of a platinum rod, encased in plum bago, was made to operate a magnifying device, which moved a pointer over a scale divided so as to read temperatures directly. Although inaccurate as com pared with modern instruments; this pyrometer was the first to give a continuous reading, and required no personal attention. The expansion pyrometer - with different expanding substances - is still used to. A limited extent. The year 1822 was also marked by Seebeck's discovery of thermo-electricity. The generation Of a current of electricity by a heated junction Of two metals, increasing with the temperature, appeared to afford a simple and satisfactory basis for a pyrometer, and Becquerel constructed an instrument on these lines in 1826. Pouillet and others also endeavoured to measure temperatures by the thermo-electric method, but partly owing to the use of unsuitable junctions, and partly to the lack of reliable galvanometers, these workers failed to Obtain concordant results. The method was for all practical purposes abandoned until 1886, when its revival in reliable form led to the enormous extension Of the use of pyrometers witnessed during recent years.
