Axiomatization Decision LogRegistro de Decisões
1 Identity-Giving FunctionFunção Identitária
Function class
PressureTransmissionFunction
⊑ SignalTransmissionFunction
Realized in
PressureSignalTransmissionProcess
⊑ SignalTransmissionProcess
The identity-giving function is the specialized transmission of pressure measurement data as standardized output signals. This is a subtype of the already-defined SignalTransmissionFunction, specifically for pressure variables. The function realizes the conversion of pressure sensing to communication-ready signals.
2 Genus DeterminationDeterminação do Gênero
transmitterbfo:Object (BFO_0000030)
From parent_candidates, 'transmitter' is the most specific appropriate superclass and is already enriched in our ontology with SignalTransmissionFunction. ISO 15926 confirms this inheritance path through PROCESS VARIABLE TRANSMITTER. 'PRESSURE MEASURING INSTRUMENT' is a lateral classification axis (measurement vs transmission), while 'transmitter' captures the core equipment category.
3 Differentia SpecificaDiferença Específica
∃hasFunction.PressureTransmissionFunctionTransmits specifically pressure measurement signals rather than other process variables.
The differentia is the specialization to pressure variables. Since transmitter already provides the generic signal transmission capability, only the process variable specificity (pressure) distinguishes this from other transmitter types.
4 Necessary PartsPartes Necessárias
No necessary parts recorded.
These parts constitute the minimal functional architecture: sensing, conditioning, and process interface. Specific sensor technologies (capacitive, piezoresistive) vary by subtype.

TransformationTransformação
pressure measurement signal converted to standardized transmission signal
Signature reflects the signal transduction from pressure sensing to communication-ready output, requiring electrical power for active signal conditioning and transmission.

C2: FlowTransmitter, TemperatureTransmitter, LevelTransmitter. Different process variable specializations with incompatible input signal types - a transmitter cannot simultaneously transmit pressure and temperature signals as its primary function
