Axiomatization Decision LogRegistro de Decisões
1 Identity-Giving FunctionFunção Identitária
Function class
DifferentialPressureTransmissionFunction ⊑ PressureTransmissionFunction
Realized in
DifferentialPressureMeasurementAndTransmissionProcess ⊑ PressureMeasurementAndTransmissionProcess
The identity-giving function is measuring the difference between two pressures and transmitting this differential as a standardized signal, which is a specific subtype of pressure transmission that requires two pressure inputs rather than one absolute pressure.
2 Genus DeterminationDeterminação do Gênero
pressure transmitterbfo:Object (BFO_0000030)
ISO 15926 explicitly states this is a subtype of PRESSURE TRANSMITTER. The parent_candidates include 'pressure transmitter' which is already enriched in our ontology. This is the most specific appropriate superclass - more specific than 'transmitter' but still a genuine supertype of differential pressure transmitter.
3 Differentia SpecificaDiferença Específica
∃bearerOf.DifferentialPressureTransmissionFunction

Bears a differential pressure transmission function that measures and transmits the difference between two pressure inputs rather than a single absolute pressure.

The differentia is the specific subtype of pressure transmission function that requires two pressure inputs and computes their difference, which is not provided by the genus pressure transmitter that covers general pressure measurement and transmission.
4 Necessary PartsPartes Necessárias

No necessary parts recorded.

Differential pressure transmitters require specialized components to handle two pressure inputs and compute their difference, beyond the basic signal transmission components inherited from the transmitter genus.

TransformationTransformação
pressure difference calculation and signal conversion
The signature requires two pressure inputs to compute differential, distinguishing it from single-input pressure transmitters. Output is standardized signal proportional to pressure difference.
