Every gas detector is a detector that bears a GasDetectionFunction and has a GasDetectingMeasuringElement as component part at all times.First-Order Logic TheoryTeoria em Lógica de Primeira Ordem
[Definition]∀x (GasDetector(x) ↔ Detector(x) ∧ ∃f (GasDetectionFunction(f) ∧ bearerOf(x,f))) — Steps 1–3: genus + identity-giving function
[Function axiom: GasDetectionFunction]∀f (GasDetectionFunction(f) → ∀p (realizedIn(f,p) → GasDetectionProcess(p)) ∧ ∃p (GasDetectionProcess(p) ∧ realizedIn(f,p))) — Step 1: ∀ preserves type-type identity; ∃ rules out vacuous functions never realised
[Necessary part: GasDetectingMeasuringElement]∀x (GasDetector(x) → ∃p (GasDetectingMeasuringElement(p) ∧ hasComponentPartAtAllTimes(x,p))) — Step 4: mereological commitment — every instance must have this part

Axiomatization Decision LogRegistro de Decisões
1 Identity-Giving FunctionFunção Identitária
Function class
GasDetectionFunction
⊑ DetectionFunction
Realized in
GasDetectionProcess
⊑ DetectionProcess
The identity-giving function is gas detection - sensing the presence of a specified concentration of gas. This is a specialization of the general DetectionFunction already established in the ontology for the detector class.
2 Genus DeterminationDeterminação do Gênero
Detectorbfo:Object (BFO_0000030)
The parent_candidates and all source definitions consistently identify this as a specialized type of detector. The detector class is already enriched in our ontology with DetectionFunction and Assembly genus, making it the appropriate immediate superclass.
3 Differentia SpecificaDiferença Específica
∃bearerOf.GasDetectionFunctionHas the specific designed function to detect gas presence at specified concentrations.
The differentia is the specific GasDetectionFunction - the capability to sense gas presence at specified concentrations. This is more specific than the generic DetectionFunction inherited from detector, and distinguishes gas detectors from other detector subtypes.
4 Necessary PartsPartes Necessárias
| Part class | Parent | Relation |
|---|---|---|
| GasDetectingMeasuringElement | MeasuringElement | hasComponentPartAtAllTimes |
Gas detectors require a specialized gas-detecting measuring element as their core sensing component. General sensing elements inherited from detector are too broad for this specialized detection function.

TransformationTransformação
chemical/physical sensing - converts gas concentration to detection signal
Gas detectors take atmospheric gas portions as input and produce detection signals indicating concentration levels. The transformation involves chemical or physical sensing mechanisms.
