266PSH.A.S.K.B.1.B.7.E1.L9.R1.B2: 266PSH gauge transmitter: DP-style configuration and replacement checks
The ABB 266PSH is a gauge-pressure transmitter in a DP-style configuration. The supplied designation contains option positions that must be decoded against the matching ABB order information. Because the 266 product documentation includes legacy and limited product references, verify availability, hardware revision and any approved successor before specifying a new installation.

| Lifecycle | Confirm current availability and approved replacement path |
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
Use the instrument only after confirming that the process connection, pressure range, static-pressure conditions, wetted materials and output protocol match the application. Gauge pressure references atmosphere; ensure the installation and venting arrangement preserve the intended reference. Do not infer a calibrated range from the family name or a partial type code.
Configuration and compatibility
Review the complete suffix for sensor code, connection, housing, output and accessory choices. Confirm certificates, temperature limits and maintenance spares from the applicable documentation. If replacing an existing unit, record the nameplate, firmware and configuration parameters and compare them with the proposed successor before removing the installed transmitter.
Related models and order-code references
The following designations are related catalog references, not automatic substitutes. Check each complete code, rating, connection, revision and application requirement before selecting a variant.

Installation and commissioning
Install with suitable process isolation and pressure-rated fittings. Check orientation, vent/drain access and electrical grounding, then apply pressure using an approved calibration source. Verify zero, span, loop output and diagnostics under the correct reference condition; retain calibration records and the exact configuration code for future service.
Replacement and procurement information
For a quotation or replacement review, provide the complete designation 266PSH.A.S.K.B.1.B.7.E1.L9.R1.B2, 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.
