The effect of pressure-transmitting fluids in the characterization of a controlled clearance piston gauge up to 1 GPa

Abstract

The present paper describes the effect of different pressure-transmitting fluids (PTFs) on the systematic characterization of an oil-operated controlled clearance piston gauge (nominal diameter of the piston, 2.5 mm) in the pressure range up to 1000 MPa (1 GPa). Pure PTFs and mixtures of different PTFs are studied and four of them will be discussed here: namely (a) pure normal hydraulic oil (J-13), (b) a mixture of J-13 and an aviation turbine fuel (ATF), (JATF), (c) a pure di-ethyl-hexyl-sebacate oil (BIS) and (d) a mixture of white gasoline (G), J-13 and sebacate (GJBIS).
