11. Faster, Better, Cheaper: New Automated Vacuum Calibration Service at NIST
Published: 10/1/2012
Authors: Jacob E Ricker, Jay H Hendricks, Douglas A Olson, Gregory F Strouse
Abstract: In today‰s fast-paced world and ever expanding quality assurance requirements, the National Institute of Standards and Technology (NIST) has developed a system to fill the need for faster, better, and cheaper low pressure calibrations (0.65 Pa to 130 ...

12. Results of a hydraulic pressure comparison in the range from 25 MPa to 200 MPa between NIS-Egypt and NIST-USA
Published: 2/28/2012
Authors: Douglas A Olson, Alaaeldin A Eltawil, Shaker A Gelany
Abstract: The results of an informal pressure comparison between the National Institute of Standards and Technology (NIST), USA, and the National Institute of Standards (NIS), Egypt, are presented. The comparison was aimed to determine degree of equivalence be ...

13. A gas pressure scale based on primary standard piston gauges
Published: 12/6/2010
Authors: Douglas A Olson, Robert G Driver, Walter J. Bowers Jr.
Abstract: The National Institute of Standards and Technology has redefined its gas pressure scale, up to 17 MPa, based on two primary standard piston gauges. The primary standard piston gauges are 35.8 mm in diameter and operate from 20 kPa to 1 MPa. Ten sec ...

14. Final report of key comparison CCM.P-K3 absolute pressure measurements in gas from 3E-6 Pa to 9E-4 Pa
Published: 3/31/2010
Authors: Douglas A Olson, Patrick J Abbott, Karl Jousten, Fiona J Redgrave, Pardeep Mohan, S S Hong
Abstract: This report describes a CCM key comparison of absolute pressure at five National Metrology Institutes (NMIs) that was carried out from August 1998 to May 2002. The goal of the key comparison was to determine the degree of equivalence at pressures in ...

15. A Capacitive Probe for Measuring the Clearance Between the Piston and the Cylinder of a Gas Piston Gauge
Published: 3/10/2010
Authors: Walter J. Bowers Jr., Douglas A Olson
Abstract: We propose a method of determining the radial clearance between the piston and cylinder of a gas piston gauge using a capacitive technique. This method allows a determination of the effective area of a piston gauge pressure standard, independent of ...

16. 1 Pa TO 15 000 Pa ABSOLUTE MODE COMPARISONS BETWEEN THE NIST ULTRASONIC INTERFEROMETER MANOMETERS AND NON-ROTATING FORCE-BALANCED PISTON GAUGES
Published: 1/11/2010
Authors: Jay H Hendricks, Douglas A Olson
Abstract: The National Institute of Standards and Technology (NIST) Low Pressure Manometry Project maintains and operates primary standard ultrasonic interferometer manometers (UIMs) over the pressure range of 1 mPa to 360 kPa. Over the past decade a new type ...

18. Towards portable vacuum standards
Published: 8/1/2009
Authors: Jay H Hendricks, Douglas A Olson
Abstract: Since the middle of the 17th century, when Italian physicist Evangelista Torricelli discovered that a glass tube filled with mercury could be used to measure atmospheric pressure, liquid-column manometers have been used as a primary standard to measu ...
