Multiple-self-reversed-rotations: 35 mm dia. PCA @ 5 kPa

Multiple-self-reversed-rotations: 35 mm dia. PCA @ 5 kPa Tube. Duration : 1.57 Mins.

A new prototype gas-operated & gas-lubricated Primary Dead Weight Pressure Balance with 1 MPa pressure measuring range (using a 35 mm diameter PCA of tungsten carbide - 10 kPa/kg) which is designed and manufactured by: PETRO PRECISION SDN. BHD. No. 19, Jalan Kota Raja H27/H, Pusat Bandar HICOM Seksyen 27, 40400 Shah Alam, Selangor, MALAYSIA. Tel: +603-51922933 / 51922934 Fax: +603-51922953 Email: petroprecision@gmail.com EXPECTED METROLOGICAL SPECIFICATIONS:  Uncertainty of measurement: approximately 10 ppm (k = 2)  Sensitivity: less than 1 ppm  Long term stability: less than 1 ppm/year  Repeatability: less than 1 ppm  Resolution of measurement: 0.1 ppm OTHER FEATURES:  Fully manual-operated system  Identical performances in CW & CCW rotations  Specially designed/constructed resembling a "Built-in Temperature Stabaliser System"  PCAs' sizes could be manufactured (upon request) based on the local gravity value of the end user's location eg 9.78059 m/s2 in Malaysia  Could accommodate PCAs of 3 common sizes: 10 kPa/kg, 20 kPa/kg & 50 kPa/kg, therefore pressure measuring ranges would be 1 MPa, 2 MPa and 5 MPa respectively
