Axiomatization Decision LogRegistro de Decisões
1 Identity-Giving FunctionFunção Identitária
Function class
PressureIndicatingAndTransmissionFunction ⊑ DesignedFunction
Realized in
PressureIndicatingAndTransmissionProcess ⊑ PlannedProcess
This device has dual identity-giving functions: pressure indication (local display) and pressure transmission (signal output). This distinguishes it from pure pressure transmitters that only transmit or pure pressure indicators that only display locally.
2 Genus DeterminationDeterminação do Gênero
transmitterbfo:Object (BFO_0000030)
The ISA tag structure places this as a specialized type of transmitter ('T' suffix). The already-enriched 'transmitter' class with SignalTransmissionFunction is the appropriate genus, as this device extends basic transmission capability with local indication.
3 Differentia SpecificaDiferença Específica
∃bearerOf.PressureIndicatingAndTransmissionFunction ⊓ ∃participatesIn.PressureIndicatingAndTransmissionProcess

A transmitter that both measures and indicates pressure locally while simultaneously transmitting pressure signals to remote systems.

The differentia specifies pressure as the measured variable and adds the critical local indication capability that distinguishes this from pure pressure transmitters. The dual function is the key distinguishing feature.
4 Necessary PartsPartes Necessárias

No necessary parts recorded.

All parts are necessary for the dual function of pressure measurement, local indication, and signal transmission.

TransformationTransformação
pressure transduction to electrical signal plus local visual indication
Single pressure input is converted to both electrical output signal and local visual display, enabling both remote monitoring and local observation.
Disjoint WithDisjunto com
temperature transmitter flow transmitter level transmitter
C2: temperature transmitter, flow transmitter, level transmitter. Different measured variables (pressure vs temperature vs flow vs level) represent incompatible process signatures - a single device cannot simultaneously measure fundamentally different physical quantities.
