Book Synopsis Piston Manometer as an Absolute Standard for Vacuum-gage Calibration in the Range 2 to 500 Millitorr by : Isidore Warshawsky
Download or read book Piston Manometer as an Absolute Standard for Vacuum-gage Calibration in the Range 2 to 500 Millitorr written by Isidore Warshawsky and published by . This book was released on 1972 with total page 28 pages. Available in PDF, EPUB and Kindle. Book excerpt: A thin disk is suspended, with very small annular clearance, in a cylindrical opening in the base plate of a calibration chamber. A continuous flow of calibration gas passes through the chamber and annular opening to a downstream high vacuum pump. The ratio of pressures on the two faces of the disk is very large, so that the upstream pressure is substantially equal to net force on the disk divided by disk area. This force is measured with a dynamometer that is calibrated in place with dead weights. A probable error of + or - (0.2 millitorr plus 0.2 percent) is attainable when downstream pressure is known to 10 percent.

Book Synopsis Total and Partial Pressure Measurement in Vacuum Systems by : John Henry Leck
Download or read book Total and Partial Pressure Measurement in Vacuum Systems written by John Henry Leck and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 208 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book deals with the underlying theory and practical aspects of pressure gauges that are at present in general use. Because of the ever-increasing demands to provide a wider range of sophisticated and reliable vacuum equipment a good understanding of these instruments is of vital importance to all workers in the research and industrial sectors. Of the gauges considered only the mechanical types are absolute, in the sense that they measure pressure directly as a force upon a liquid column or a solid surface. Under ideal conditions it is possible to calculate their sensitiv ities, which are the same for all gases and vapours. The recent developments in the viscous or molecular damping gauges indicate that these may also be considered absolute. Other gauges are indirect in that they involve the measurement of some secondary phenomenon which is pressure-dependent and therefore these gauges can only be used for measurement after calibration against an absolute standard. The radiometer or Knudsen type gauge has been excluded from the text since these are now only of historic interest. Also no mention is made of the integration techniques involving surface changes (such as work function) although these could have application under very special circumstances. The McLeod gauge is dealt with in some detail, for even though this gauge has few practical applications, it is the most sensitive absolute gauge available and has value as a reference standard.

Book Synopsis Method of Calibrating Weights for Piston Gages by : H. E. Almer

Available in PDF, EPUB and Kindle. Book excerpt: Generally weights for piston gages have odd denominations that are often not readily calibrated by intercomparison methods.Therefore these weights are frequently calibrated by direct comparison methods.This paper presents direct comparison methods for calibrating piston gage weights for use with both equal-arm balances and single-pan balances.Methods of estimating the uncertainty of the values obtained are given.Also included are methods of checking for blunders or gross errors.(Author).
