Axiomatization Decision Log
1
Identity-Giving Function
Function class
DetectionFunction
⊑ DesignedFunction
Realized in
DetectionProcess
⊑ MeasurementProcess
Detection is the identity-giving function across all sources - the capability to sense/detect states, substances, or phenomena and produce signals based on this detection. This distinguishes detectors from other instrumentation that may measure, indicate, transmit, or control.
2
Genus Determination
Instrument
The parent candidates show 'instrument equipment' (CFIHOS) and 'INSTRUMENTATION FUNCTION' (ISO 15926). While 'Instrument' is not explicitly in the already-enriched list, multiple enriched transmitters and indicators reference 'Instrument' as their genus. Detectors are clearly instrumentation devices - assemblies with sensing elements and signal generation capabilities, fitting the Assembly branch as causally unified artifacts.
3
Necessary Parts
| Part class | Parent | Relation |
|---|---|---|
| SensingElement | MaterialArtifact | hasComponentPartAtAllTimes |
These parts reflect the two-stage nature of detection described across sources: sensing/detection of phenomena, and signal generation based on that detection.
4
Process Participation Signature ⟨I, O, T⟩
Inputs (I)
—
Outputs (O)
InformationContentEntity
— proportional to detected phenomenon
Transformation (T)
transduction from physical phenomenon to electrical signal
Detectors transform physical phenomena (pressure, temperature, gas presence, etc.) into electrical signals that can be processed by control systems or other instrumentation.
5
Axiom Mode Decision
Necessary + Sufficient
— modelled as a defined class
(≡, EquivalentClass). Automatic classification is
appropriate for this concept.
Disjointness Axioms
Actuator
C4: Actuator. Detectors sense phenomena and produce signals (input: physical → output: signal) while actuators receive signals and manipulate physical systems (input: signal → output: physical action). These have opposite transformation signatures.
Cross-Standard Observations
Strong consistency across sources on the core detection and signal generation capabilities. ISO 15926 treats it as a function, while CFIHOS and ISA treat it as physical objects - both perspectives are captured in the functional classification with structural parts. SLB focuses on specific application domains (geophysics) but maintains the same conceptual core.
