From raw P&ID image to validated, export-ready Instrument Index in minutes — not days.
Upload any P&ID image (JPG, PNG, TIFF, PDF). Claude Vision AI reads every instrument bubble, tag number, and symbol using ISA S5.1 standard.
Extracts tag numbers, instrument types, measured variables, loop numbers, service descriptions, associated equipment, and P&ID references.
Identifies all FV, PV, TV, LV control valves with actuator type, fail position (FC/FO/FL), positioner, solenoid, and limit switch status.
Detects SDV, ESDV, BDV, MOV valves with safety function, ESD level, SIL classification, and fail-safe position for SIS documentation.
Identifies AIT, pH, O₂, H₂S, CO₂, GC and other analyzers with measured variable, range, and sample conditioning details.
Automatic ISA tag validation, duplicate detection, missing loop numbers, orphan instruments, and confidence scoring with REVIEW REQUIRED flagging.
Export the complete Instrument Index, Control Valve Index, Shutdown Valve Index, Analyzer Index, and Validation Report to CSV, Excel, or print-ready PDF.
Organise multiple P&IDs under projects. Compare, manage, and export across an entire plant area or unit.
PIDNexus recognizes all standard ISA S5.1 instrument designations used in Oil & Gas and Process Industries.
Join instrumentation engineers using PIDNexus to eliminate manual P&ID extraction work.
