266DRH.F.S.R.R.R.A.1.E1.L1.B1.C1.H3: 266DRH transmitter: remote-seal application and configuration review
The ABB 266DRH is a differential-pressure transmitter configured with remote diaphragm seals. ABB describes use for liquid, gas or steam flow and for level, pressure or density measurement. Its family accuracy starts from ±0.06%, and family span limits extend from 4 to 16,000 kPa; the selected sensor and code determine the actual calibrated span.

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
Remote seals are used when direct impulse connections are unsuitable because of process temperature, plugging, corrosive media, sanitation or access. The seal, capillary length, fill fluid, mounting elevation and ambient conditions all affect response and zero shift. Select the assembly as a complete system rather than treating the transmitter body as the only measurement element.
Configuration and compatibility
Decode every configuration position from the applicable ABB ordering documentation. Confirm diaphragm and flange material, process connection, seal construction, capillary length, fill fluid, output protocol, approvals and mounting hardware. A family range or accuracy value must not be presented as the exact span or tolerance of the listed code without the order record.

Installation and commissioning
Mount the seals and capillaries without kinks, twist or unintended thermal gradients. Follow the specified orientation and elevation compensation, then perform zero trim under the correct equalized condition. Commission with the process isolated, verify scaling and diagnostics, and document the full code, seal data, capillary dimensions and calibration reference.
Replacement and procurement information
For a quotation or replacement review, provide the complete designation 266DRH.F.S.R.R.R.A.1.E1.L1.B1.C1.H3, 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.
