pressure

Test Process that measures a gas’s density as defined by the amount of mass present in a specified volume of gas at a given temperature and pressure. Gases are extremely responsive to temperature and pressure, causing their densities to change rather quickly. Measuring the density of gas the Ideal Gas Law (P*V = nRT) must be taken into account. ** Includes non-uniformity

Test Process that measures a liquid’s density as defined by the amount of mass present in a specified volume of liquid at a given temperature. Temperature affects density, as does the pressure to the extent that the liquid compresses. In, liquids deemed sufficiently incompressible, the volume does not depend on pressure. ** Includes non-uniformity and voids (if any)

This test process measures the pneumatic differential pressure between two points generated by the unit under test. The resulting pressure difference 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. https://en.wikipedia.org/wiki/Pressure_measurement https://www.nxp.com/docs/en/application-note/AN1573.pdf?&srch=1

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

Test Process that measures the relative density, or specific gravity, is the ratio of the density (mass of a unit volume) of a substance to the density of a given reference material. Specific gravity for liquids is nearly always measured with respect to water at its densest (at 4 °C or 39.2 °F); for gases, air at room temperature (20 °C or 68 °F) is the reference. The term “relative density” is often preferred in scientific usage. It is defined as a ratio of the density of a particular substance with that of water.

Measuring the ratio of the water vapor’s partial pressure divided by the saturation water vapor pressure allowed at a given temperature.

A test process that measures the accuracy of hydraulic torque wrenches where hydraulic pressure is applied to the torque wrench and it applies a known torque to the nut or bolt being tightened. This process usually is used to calibrate hydraulic torque wrenches producing a lookup sheet the operator can use to quickly look up the pressure required to correctly torque the bolt or nut.

This process sources a reference mass flow rate of gas for calibrating gas-flow meters. The instantaneous mass flow rate q_m equals dm/dt, sometimes estimated as ∆m/∆t using the total mass ∆m flowing through a defined surface in time ∆t.

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.
