DEVELOPMENT OF ABSOLUTE MODE PRESSURE STANDARD IN THE RANGE FROM 25 kPa UP TO 2 MPa

This paper presents pressure calibration system in the absolute pressure range of 25 kPa to 2 MPa, which is being developing in Croatian national pressure laboratory- Laboratory for Process Measurement (LPM) at Faculty of Mechanical Engineering and Naval Architecture (FSB) in Zagreb. Design of the system, theoretical basis, main parameters influencing the effective pressure and the model for estimation of measurement uncertainty are described. The scope of the system is presented through absolute pressure uncertainty budget.
