Axiomatization Decision LogRegistro de Decisões
1 Identity-Giving FunctionFunção Identitária
Function class
TemperatureIndicationFunction ⊑ IndicationFunction
Realized in
TemperatureIndicationProcess ⊑ PlannedProcess
The identity-giving function is to measure temperature and display the measured value locally. This function already exists in the enriched classes for 'analogue temperature indicator', so we reuse the same function name. The function is distinct from temperature transmission (which produces remote signals) by being limited to local indication.
2 Genus DeterminationDeterminação do Gênero
indicatorbfo:Object (BFO_0000030)
Temperature indicator is a type of measuring instrument. While 'Instrument' appears as a genus in several enriched classes (indicator, controller, detector, etc.), it is not itself in the enriched classes list, so genus_enriched=false. The concept belongs to the Assembly branch as it consists of multiple connected components (sensing element, linkage, display) that form a causally unified measurement device.
3 Differentia SpecificaDiferença Específica
∃hasInput.Temperature ⊓ ∃hasOutput.LocalTemperatureDisplay

Measures temperature as input and produces local temperature display as output, without remote signal transmission capability.

The differentia focuses on temperature as the measured variable and local-only display as the output characteristic. This distinguishes it from other instruments that measure different variables or provide remote transmission capabilities.
4 Necessary PartsPartes Necessárias

No necessary parts recorded.

These three components are essential for any temperature indicator: sensing element to detect temperature, display to show the value, and some form of linkage to transmit the signal from sensor to display.

TransformationTransformação
temperature sensing and local indication without remote signal generation
Temperature indicators have a simple signature: they sense temperature at one location and display it locally. Unlike transmitters, they do not produce standardized remote output signals.
