Abstract

A study on the characterization of a controlled-clearance piston gauge was performed at the National Institute of Standards and Technology (NIST). The characterization covers the pressure range from 37.5 MPa to 288 MPa, at jacket pressures up to 76 MPa. In this study, the Heydemann-Welch model was used to define the controlled-clearance piston gauge as a primary pressure gauge. The parameters needed for the model were determined form the measurements, and the characteristics of the controlled-clearance gauge were evaluated along with their unceratinty. After the characterization of the controlled-clearance piston gauge, a transfer piston gauge was calibrated againtst the primary piston gauge. The procedure and results of the characterization and calibration are described in this paper.
