Reference standard of the pressure unit for pressure difference

The standard is created and is in operation since 2002

Reference standard of the pressure unit

Standard composition:

  • portable micromanometer PMKM with the measurement range from 100 to 4000 Pa;
  • ocular screw micrometer MOB-1-15X with the measurement range from 0 to 8 mm;
  • terminal measuring blocks, nominal value of lengths from 10 to 100 mm;
  • terminal measuring blocks, nominal value of lengths 200 and 300 mm;
  • multiturn indicator with the range of measurement from 0 to 1 mm;
  • bellows press for creation and maintenance of pressure and transfer of the unit size

 Metrological characteristics:

  • range of pressure difference reproduction – 100 - 4000 Pa;
  • non-excluded systematic error does not exceed 0,4 Pa;
  • SE does not exceed 0,1 Pa

Sources of traceability:

Russia, FSUE “All-Russian Research Institute of Metrology named after D.I. Mendeleyev”, standard micromanometer MKSH-М, which is a part of state special standard of the pressure unit for pressure difference (GET 95-75)

Scope of application:

  • for transferring of the unit of pressure by standard micromanometer of the first degree, verification, calibration, metrological attestation of high-precision means of measurement of manometric pressure: pressure gauges of accuracy class 0,02, pressure calibrators, pressure transformers with error from 0,025 % to 0,1 %;
  • for territorial bodies of Gosstandart;
  • institutes of the National Academy of Sciences of the Republic of Belarus;
  • for territorial bodies of Gosstandart, metrological seгvices of Beltransgaz and Beltopgaz enterprises, oil processing industry;
  • energy supplying and energy consuming economy subjects;
  • machinery
