1 Identity-Giving FunctionFunção Identitária
Function class
DifferentialPressureMeasurementFunction ⊑ PressureSensingFunction
Realized in
DifferentialPressureMeasurementProcess ⊑ PlannedProcess
The identity-giving function is the measurement of differential pressure, which distinguishes this from absolute pressure measurement or gauge pressure measurement. This function is realized through various mechanical mechanisms but the functional identity remains constant.
2 Genus DeterminationDeterminação do Gênero
pressure elementbfo:Object (BFO_0000030)
From the parent_candidates list, 'PRESSURE MEASURING ELEMENT' maps to 'pressure element' which is already enriched in our ontology. This is the most specific appropriate superclass, as differential pressure measuring elements are a specialized type of pressure sensing device. The genus is more specific than the generic 'Instrument' and captures the pressure-specific sensing capability.
3 Differentia SpecificaDiferença Específica
∃bearerOf.DifferentialPressureMeasurementFunction

Bears a differential pressure measurement function that senses pressure differences between two inputs rather than absolute or gauge pressure.

The differentia is the specific subtype of pressure measurement function that distinguishes differential pressure measurement from other pressure measurement types. This is the minimal additional condition beyond the genus that defines the species identity.

While the subtypes indicate various sensing mechanisms (bellows, bourdon tube, diaphragm, piston, liquid column), these are subtype-specific implementations rather than universal parts. The generic differential pressure measuring element concept does not mandate a specific sensing mechanism, only the functional capability.

TransformationTransformação
mechanical deflection or displacement generated proportional to the pressure difference between two fluid inputs
The signature captures the fundamental operation: two fluid pressure inputs create mechanical displacement output proportional to their difference. This distinguishes differential pressure elements from single-input pressure sensors and grounds the measurement transduction transformation.
