266GST-FKPNB1E6L1B7I2C1: 266GST gauge transmitter: range code, pressure connection and protocol verification
The ABB 266GST-FKPNB1E6L1B7I2C1 is a coded 266GST gauge-pressure transmitter configuration. The 266GST family is designed for pressure measurement in liquids, gases or steam and can also support open-tank level applications. ABB lists a ±0.04% base-accuracy family reference and several output protocols; the exact range and wetted configuration must be checked against the sensor code and nameplate.

| Representative designation | 266GST-FKPNB1E6L1B7I2C1 |
| Measurement | Gauge pressure; family use includes liquid, gas, steam and open-tank level |
| Base accuracy | ±0.04% of span family reference; optional higher accuracy depends on version |
| Family span limits | 0.2 to 60,000 kPa; exact sensor code determines usable range |
| Outputs | 4–20 mA/HART, PROFIBUS PA or FOUNDATION Fieldbus options |
| Local interface | Optional TTG display/configuration features by version |
| Configuration | Confirm full code, seals, wetted materials and approvals |
The table summarizes family or catalog values for identification and initial selection. Confirm the nameplate, environmental limits, standards, revision and options for the exact device before procurement or engineering approval.
Application and system selection
Start with the process medium, static pressure, expected gauge range, overpressure events and required turndown. For open-tank level, also evaluate fluid density, vessel geometry and mounting elevation. Select seals and wetted materials for compatibility with the process and temperature, then coordinate the output protocol with the control system.
Configuration and compatibility
The long order string contains configuration choices that should not be inferred from a partial model name. Verify sensor span, process connection, diaphragm material, fill fluid, output, approvals and display options from the matching ABB configuration record. A nominal family accuracy does not replace range-specific uncertainty and installation checks.

Installation and commissioning
Install with pressure-rated fittings and an orientation suitable for the process connection. Isolate and depressurize before maintenance, check impulse-line routing and vent access, and ground the loop correctly. Commission zero and span with a traceable pressure reference, verify diagnostics and output scaling, and retain the final configuration record.
Replacement and procurement information
For a quotation or replacement review, provide the complete designation 266GST-FKPNB1E6L1B7I2C1, the order code where applicable, serial or hardware revision, quantity, operating environment, connected equipment and required delivery date. Include a legible nameplate image and relevant wiring, loop or switchgear drawing so the exact interface and configuration can be checked.
Ask the supplier to confirm accessories, revision compatibility and any approved successor in writing. Do not select solely from a family name or product photograph. Follow the current ABB installation and safety instructions for the exact unit.
