Abstract

The National Metrology Institute of Japan, AIST (NMIJ/AIST) has developed the high gas pressure standard for pressures up to 100 MPa for more reliable pressure measurements. A high gas pressure calibration system using a liquid-lubricated pressure balance has been developed. The effective area of the piston-cylinder assembly is determined from the comparison against hydraulic pressure balances. Calibration results of a pressure transducer are compared with those using the hydraulic pressure standard.
