Metrology Taxonomy

This test process generates the pneumatic absolute pressure to be measured by the unit under test. The resulting measured will be in the unit of measure as defined in the test point’s data.

Note: Although the unit of measure can be read from the test point’s unit of measure it is good practice to pass the Unit of Measure to the test process as a parameter to avoid confusion when synchronizing data between systems.

Measured Value & Uncertainty

Pressure 

This test process generates the hydraulic pressure to be measured by the unit under test. The resulting measured will be in the unit of measure as defined in the test point’s data.

Note: Although the unit of measure can be read from the test point’s unit of measure it is good practice to pass the Unit of Measure to the test process as a parameter to avoid confusion when synchronizing data between systems.

Required Parameters

• Pressure 
• UnitOfMeasure – {μmHG, mmHG, mHG, μmH2O, mmH2O, mH2O, inHg, inH2O, psi, μPa,  mPa, Pa, kPa, MPa, mbar, bar, Torr}

Optional Parameters

• Fluid – {Oil, Water}

Measured Value & Uncertainty

• Pressure 

This test process generates two pneumatic pressures with a known differential pressure between two points measured by the unit under test.  The resulting differential pressure will return in the unit of measure as defined in the test point’s data.

Note: Although the unit of measure can be read from the test point’s unit of measure it is good practice to pass the Unit of Measure to the test process as a parameter to avoid confusion when synchronizing data between systems.

Optional Parameters

• O2_Safe – “Yes” If the Gage in an O2 environment

Measured Value & Uncertainty

• Pressure 

This test process generates the pneumatic gage pressure (or relative pressure) to be measured by the unit under test. The resulting measured will be unit of measure as defined in the test point’s data.

Note: Although the unit of measure can be read from the test point’s unit of measure it is good practice to pass the Unit of Measure to the test process as a parameter to avoid confusion when synchronizing data between systems.
