Axiom type
LLM classification basis: function-based → ≡
The concept is defined by its dual function: indicating pressure (providing local visual display) and transmitting pressure signals. The ISA 5.1 abbreviation confirms this functional basis with 'I' for Indicate and 'T' for Transmit. The identity is given by what the device does, not its internal measurement mechanism.

Identity-Giving Function
✓ done
PressureIndicatingAndTransmissionFunction → PressureIndicatingAndTransmissionProcess ⊑ MeasurementProcess
▼
COPI-Core operation
MeasurementProcess via process parent MeasurementProcess
LLM rationale:
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.

Genus (genus proximum)
Most specific superclass — may be a domain class like "Valve" or an IOF-Core root.
BFO/IOF-Core Root
bfo:Object branch
bfo:ObjectAggregate branch
bfo:ImmaterialEntity branch
LLM rationale:
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.

Conditions that distinguish
Pressure Indicating Transmitter
from sibling classes under genus
Transmitter.
Only what is not already entailed by the genus.
Differentia expression
Differentia (natural language)
LLM rationale:
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.

Necessary Parts
✓ done
no necessary parts
▼
Consider part-whole relations beyond subsumption:
hasComponentPartAtAllTimes (universal, structurally essential)
· hasComponentPartAtSomeTime (contingent, optional component)
LLM rationale:
All parts are necessary for the dual function of pressure measurement, local indication, and signal transmission.

Inputs (I)
Outputs (O)
Transformation (T)
LLM rationale:
Single pressure input is converted to both electrical output signal and local visual display, enabling both remote monitoring and local observation.
