| Abstract | The accurate generation of gauge pressures in the range from below 0.5 Pa to 2000 Pa using twin gas-operated pressure balances is described. Each gauge pressure is generated by changing the mass on one of the pressure balances while they are both operating. The performance of the twin-pressure-balance instrument was assessed by calibrating differential pressure transducers. The short-term stability of the average difference in pressure between the two pressure balances was about 0.5 mPa (standard deviation), or 5 parts in 10 9 of the line pressure, and the overall uncertainty (99% confidence limits) in the generated gauge pressure pe was ± (0.9 mPa + 2 × 10-5 pe). |
