ГЭТ 101-2011 (НИО 231)

Standard name:

ГЭТ 101-2011 State primary standard of the unit of pressure for the absolute pressure range of 1·10[^-1] ÷ 7·10[^5] Pa

Type of measurement:

Pressure measurements, vacuum measurements

Structural division: name НИО\НИЛ:

Research Department of State Standards in the Field of Pressure Measurements

Guardian Scientist:

Sadkovskaya Irina Vladimirovna

Year of creation:

1976

Year of re-confirmation:

2011

Operating principle:

The GET 101 standard includes reference installations with two different operating principles. Laser interference liquid manometers operate by balancing the measured gas pressure with a liquid column in a U-shaped manometric tube, the height of which is measured using laser interferometry. A deadweight tester operates by balancing the measured gas pressure on an unsealed piston with the weight of the piston, a load-receiving device, and weights of known mass applied to it.

Composition of the standard:

Reference system based on a laser interference oil pressure gauge;
Reference system based on a laser interference mercury pressure gauge;
Reference system based on a gas-lubricated deadweight tester.

Verification diagram:

Heads the state verification scheme for absolute pressure measuring instruments in the range of 1·10^(-1)-1·10^7 Pa

Scope of application:

Rosaviatsia, Roscosmos, Roshydromet, Gazprom, the Russian Ministry of Defense, the country's energy-saving complex, the electronic, medical, oil refining industries of the Russian Federation, instrument making and precision engineering, etc.

Results of applying the standard:

The characteristics of the improved GET 101 standard meet the needs of science and industry in the Russian Federation and allow for the verification, calibration, and testing of high-precision absolute pressure measuring instruments in the range from 1•10^-2 to 1•10⁷ Pa.
