Download or read book An Automated Vacuum Gauge Calibration System written by and published by . This book was released on 1998 with total page 16 pages. Available in PDF, EPUB and Kindle. Book excerpt: An automated system for calibrating vacuum gauges over the pressure range of 10−6 to 0.1 Pa was designed and constructed at the National Institute of Standards and Technology (NIST) for the Department of Energy (DOE) Primary Standards Laboratory at Sandia National Laboratories (SNL). Calculable pressures are generated by passing a known flow of gas through an orifice of known conductance. The orifice conductance is derived from dimensional measurements and accurate flows are generated using metal capillary leaks. The expanded uncertainty (k = 2) in the generated pressure is estimated to be between 1% and 4% over the calibration range. The design, calibration results. and component uncertainties will be discussed.
Book Synopsis A HIGH VACUUM GAUGE CALIBRATION SYSTEM. by : WALLACE S. KREISMAN

Available in PDF, EPUB and Kindle. Book excerpt: An ultra-high vacuum type metal and glass system was constructed for the purpose of calibrating vacuum gauges in the pressure region from 760 to 10 to the -7th power torr. The high vacuum portion of the system is bakeable at temperatures up to 450 C.A mercury manometer serves as a pressure standard in the region from 760 to 20 torr, and three specially designed, bakeable McLeod gauges with overlapping pressure ranges serve as pressure standards in the region from 20 torr to 1 x 1/10,000 torr. Theoretical accuracies of 1 percent or better are expected for the McLeod gauge readings in this pressure region. Pressures from 1 x 1/10,000 torr to 10 to the -7th power torr region can be measured, but the accuracy of the readings depends on adsorption and outgassing effects. Results pertaining to the reproducibility of measurements and comparisons of various gauge readings are presented. A pressure rise measurement technique is used to determine how the vacuum gauges and other system components are behaving. (Author).

Download or read book Vacuum Gauge Calibration written by AMS B Finishes Processes and Fluids Committee and published by . This book was released on 2019 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: This SAE Aerospace Recommended Practice (ARP) addresses the general procedure for the best practices for minimizing uncertainty when calibrating thermal conductivity and cold cathode vacuum gauges, which includes the vacuum sensor(s) and accompanying electronics necessary for a pressure measurement to be made. It also includes the best practices for an in-process verification where limitations make it impossible to follow the best practices for minimizing uncertainty.Verifying the accuracy and operation of vacuum gauges is critical to ensure the maintenance of processes while under vacuum. ARP7449, Vacuum Gauge Calibration, was written to provide a best practice method for the calibration and testing of vacuum measuring systems for thermal processing equipment. Prior to this ARP, there was no guidance to follow. Aerospace standards such as AMS2769 and subscribing aerospace primes require vacuum system calibration to manufacturers recommendations, but many of these recommendations lacked detail instructions on the method of calibration.
Book Synopsis Total Pressure Measurements in Vacuum Technology by : A. Berman
Download or read book Total Pressure Measurements in Vacuum Technology written by A. Berman and published by Academic Press. This book was released on 2014-06-28 with total page 413 pages. Available in PDF, EPUB and Kindle. Book excerpt: Total Pressure Measurements in Vacuum Technology focuses on the measurement of low total pressure in hostile environments or in the presence of magnetic fields. This book emphasizes the general processes and problems involved in measurement techniques and physical principles on which vacuum gauges operate, rather than on the detailed description of the gauges. The design and techniques involved in the use of special instruments that determine “pressure or gas density, such as pressure converters or radioactive gauges, are also described. This publication is mainly intended for graduate students and research scientists who have a good general background in physics and engineering.
