| Zusammenfassung | In this work, we present for the first time the mercury micromanometer experiment at PTB. Our system consists of a classical three-limb U-tube manometer for gauge pressures in the range of (-10 to 10) kPa and absolute pressures in the range between 170 mPa and 10 kPa. The length determination of the mercury columns is performed by plane mirror interferometer systems and heterodyne signal processing. As a result, we are able to demonstrate first measurements of the operation and a preliminary estimation of the combined measurement uncertainty. |
