Strain gauge manometer with pressure up to 0.5 GPa acting inside and on the ends of a free cylinder

R. Wiśniewski, G F Molinar

Abstract

A free deforming-cylinder pressure transducer with bonded strain gauges is presented for pressure measurements in liquid media up to 0.5 GPa. Description is given of its operating principle and of its main metrological properties; the overall accuracy of this prototype pressure transducer is inside ±0.25 MPa.
