DESIGN AND CHARACTERISATION OF A DOUBLE-PISTON PRESSURE BALANCE IN HIGH PRESSURE

G. Buonanno, M. Dell'Isola, A. Frattolillo

Abstract

The paper describes the design and the analysis of a new kind of pressure balance intended to operate up to 500 MPa. The design can be considered as a calculation test to evaluate the possibility to produce a pressure balance whose changes in effective area with pressure (and, consequently, the elastic distortions) are small if compared to other pressure balances operating in the same pressure range and, furthermore, it presents an extended measurement range. The method used for the theoretical characterisation is an improvement of a numerical method using a finite element method.
