Laser Interference Oil Manometer of State Primary Standard of the Unit of Pressure Get 101–2011

详细

The design, principle of operation, and budget of errors of a laser interference oil manometer developed at the Mendeleev All-Russia Research Institute of Metrology (VNIIM) and subsequently incorporated into the State Primary Standard of the unit of pressure GET 101–2011 are described. The results of studies of precision instruments for measurements of pressure with the use of the laser interference oil manometer are presented. Summaries of key comparisons and international cooperation in the field of liquid manometry are presented.
