Axiomatization Decision LogRegistro de Decisões
1 Identity-Giving FunctionFunção Identitária
Function class
ConductivityTransmissionFunction
⊑ SignalTransmissionFunction
Realized in
ConductivityTransmissionProcess
⊑ SignalTransmissionProcess
The identity-giving function combines conductivity measurement with signal transmission. This is a specialized subtype of SignalTransmissionFunction that specifically measures and transmits electrical conductivity of fluids.
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. PROCESS VARIABLE TRANSMITTER would be more specific but is not enriched. CONDUCTIVITY METER is a sibling measurement device but lacks the transmission capability that defines transmitters.
3 Differentia SpecificaDiferença Específica
∃bearerOf.ConductivityTransmissionFunctionBears a conductivity measurement function that determines electrical conductivity of process fluids.
The differentia is the specific measurement function for conductivity. The genus 'transmitter' already provides the signal transmission capability, so only the conductivity-specific measurement function distinguishes this from other transmitter types.
4 Necessary PartsPartes Necessárias
No necessary parts recorded.
These parts are necessary for all conductivity transmitters regardless of specific technology. The conductivity sensor provides measurement capability while signal conditioning enables proper transmission.

TransformationTransformação
transduction of fluid conductivity to electrical signal
Conductivity transmitters measure electrical properties of process fluids and convert to standardized electrical signals for control systems.
Disjoint WithDisjunto com
temperature transmitter pressure transmitter flow transmitter level transmitter
C2: temperature transmitter, pressure transmitter, flow transmitter, level transmitter. Different measurement signatures - conductivity measurement is incompatible with temperature, pressure, flow rate, or level measurement as primary functions
