| Abstract: | The ultra - high pressure auxiliary balance comparison apparatus used by difference pressure manganin gauges comprised of two manganin gauges and two toggle valves controlled by hydraulic pressure. According to the principle of Wheatstone bridge, the temperature drift of the apparatus was eliminated. The different pressure between two ultra - high pressure balances was represented by the potential difference. The function of measuring the difference pressure between ultra-high pressure was realized by the apparatus. |
