NullablePressureGauge

Overview

Abstract data type

A physical quantity of dimension L^-1MT^-2 (inherited from NullablePressure) for the application type pressure gauge. A pressure gauge is a pressure relative to atmospheric pressure. NullablePressureGauge is abstract and has two concrete subtypes:

• a PressureGauge is an actual value for a physical quantity with a numerical value and a unit of measurement;

• a NullPressureGauge is a null value that explicitly indicates the absence of an actual physical quantity.

Supertypes

• NullablePressure

Subtypes

• NullPressureGauge

• PressureGauge

Implementation in Proteus Schema

All data attributes with type NullablePressureGauge are implemented as DEXPI generic attributes for physical quantities.

Example
