Abstract

Metrological characteristics of 1 GPa controlled clearance piston gauge (CCPG) were investigated using a finite element method (FEM). These are a piston/cylinder distortion coefficient in free deformation mode, distortion coefficient of jacket pressure and stall pressure in controlled clearance mode. The effective area of CCPG was constant according to different applied pressure when relative jacket pressure of 17.3 % was applied. Comparison experiments with KRISS 500 MPa standards were carried out to verify the FEM results.
