1 Identity-Giving FunctionFunção Identitária
Function class
PressureSensingFunction ⊑ DesignedFunction
Realized in
PressureSensingProcess ⊑ PlannedProcess
The identity-giving function is sensing pressure - converting pressure variations into detectable signals or responses. This is what makes a pressure element distinct from other detecting elements like temperature or flow elements.
2 Genus DeterminationDeterminação do Gênero
Instrumentbfo:Object (BFO_0000030)
The most specific superclass is 'detecting element' from CFIHOS. This is more specific than 'Instrumentation And Control Equipment' from POSC Caesar. DetectingElement represents devices that sense physical parameters - pressure element is a subtype that specifically senses pressure.
3 Differentia SpecificaDiferença Específica
∃bearerOf.PressureSensingFunction

A detecting element that specifically senses pressure variations.

The differentia is the specific pressure sensing function, which distinguishes it from other detecting elements that sense different physical parameters.
4 Necessary PartsPartes Necessárias

No necessary parts recorded.

A pressure element requires a pressure-responsive component to function, though the specific mechanism can vary (mechanical, electronic, etc.)

pressure-to-signal transduction
Pressure elements transduce pressure variations into detectable signals (mechanical displacement, electrical signal, etc.)
Disjoint WithDisjunto com
temperature element flow element level element
C2: temperature element, flow element, level element. Different sensing functions are mutually exclusive - a single element cannot simultaneously sense pressure and temperature as distinct parameters
