The Reduction of Uncertainties for Absolute Piston Gage Pressure Measurements in the Atmospheric Pressure Range
نویسندگان
چکیده
NIST pressure calibration services with nitrogen are now based on two transfer standard piston gages for which the effective areas have been determined by calibration with the manometer developed at NIST for gas thermometry. Root-sum-squared three sigma uncertainties for the areas for the two gages are 3.05 ppm and 4.18 ppm.

A Double-Primary Dead-Weight Tester for Pressures (35–175) kPa in Gage Mode
Primary pressure standards in the atmospheric pressure range are often established using mercury manometers. Less frequently, controlled-clearance dead-weight testers in which one component (normally the piston) has been dimensionally measured have also been used. Recent advances in technology on two fronts i) the fabrication of large-diameter pistons and cylinders with good geometry; and ii) t...
متن کاملA Method of Traceability for a Fpg8601 Force Balanced Piston Gauge to Define Pressures in the Range from 1 Pa to 15 Kpa in Gauge and Absolute Measurement Modes
The FPG8601 has become an important reference for many primary measurement laboratories in a pressure range from approximately 1 Pa to 15 kPa in both gauge and absolute measurement modes. The FPG8601 measurement range spans the gap between the traditional measurement regimes of ‘pressure’ and ‘vacuum’, a range where other primary pressure standards either do not exist or do not have uncertain...
متن کاملAn Investigation on the Effects of Gas Pressure Drop in Heat Exchangers on Dynamics of a Free Piston Stirling Engine
This paper is devoted to study the effects of pressure drop in heat exchangers on the dynamics of a free piston Stirling engine. First, the dynamic equations governing the pistons as well as the gas pressure equations for hot and cold spaces of the engine are extracted. Then, by substituting the obtained pressure equations into the dynamic relationships the final nonlinear dynamic equations gov...
متن کاملCharacterization of a compact 200 MPa controlled clearance piston gauge as a primary pressure standard using the Heydemann and Welch method
Controlled clearance piston gauges are used as primary pressure standards at many national metrology institutes. The National Institute of Standards and Technology, in collaboration with the National Physical Laboratory (India), is studying the performance of a new generation of controlled clearance gauges that offer the potential for reduced uncertainties. The gauges are also well suited to in...
متن کاملNon-thermal atmospheric pressure plasma source design and construction using Argon as the working gas for wound healing
In this research, a non-thermal atmospheric pressure plasma jet device was constructed for skin wound treatment. For this reason, five mice were treated for five consecutive days for 30 s, in a daily manner. Natural wound healing time was monitored and compared with the treated one in 12 consecutive days. The measurement of voltage, current and power waveforms of the plasma source, the optical ...
