Build a Rosemount 3051 order code from your specs
Walk the published ordering matrix one position at a time. The builder assembles the model string as you go, explains every segment against the product data sheet page it came from, and refuses to assemble a string the source does not tabulate.
Rosemount 3051 ordering information lives in an ordering matrix inside a product data sheet, and the real configurator sits behind a login. This tool runs the matrix in the open: pick the measurement type, the pressure range, the output protocol, the flange and diaphragm materials, the o-ring, the fill fluid, and the housing, and the model string assembles left to right in front of you.
It covers two platforms. The 3051C coplanar platform gives you 3051CD differential, 3051CG gage, and 3051CA absolute from the same eight required positions, with the measurement type at position 1 selecting the variant. The 3051SAL scalable level platform runs eleven required positions plus a seal style position that opens one of nine seal branches, each with its own connection and capillary positions. Both are modelled from the audited decoder data set, copied in with a provenance header, so the builder and the decoder can never drift apart.
Two behaviours make it worth trusting with an order. First, an option is offered only where the source table gives a meaning for the path you are on. Where the table says a code is not valid for that path, or gives no meaning at all, the code is withheld and assembly is blocked rather than guessed. Second, once every position has a code the assembled string is decoded back through the same engine the decoder uses, segment for segment. A string that does not read back cleanly is never shown. Options the data sheet flags as common are starred, and the Use standard options button fills every remaining position with the starred code and then stops where the source has no common option, which is exactly where a human has to make the call.
Some restrictions in the ordering table exist only as sentence text and are never broken out into codes. The tool does not check those and does not guess what they mean. It lists them under Restrictions this tool could not check, with the page number, so they get read against the order before it goes out. The finished string comes with a configuration-data-sheet-style request for quote block you can copy straight into an email to a distributor.
Already have a number? Decode it. The decoder reads a 3051C or 3051SAL string back into ranges, materials, and approvals.

-
Pick the platform
Choose the 3051C coplanar platform for differential, gage, or absolute pressure, or the 3051SAL scalable level platform for a level transmitter with the seal system built into one model number. Each platform card shows the product data sheet, revision, and page range its rows came from.
-
Work down the positions in order
Positions open left to right because later options depend on earlier ones. On the 3051C that is measurement type, pressure range, transmitter output, materials of construction, isolating diaphragm, o-ring, sensor fill fluid, and housing material. On the 3051SAL it is performance class, configuration type, pressure module type, pressure range, transmitter output, housing style, seal system type, high side connection, low side connection or capillary inner dimension, capillary length, and seal fill fluid.
-
Read the starred options first
A starred option is one the product data sheet flags as common. They sort to the top of every position. Use standard options fills every remaining position with the starred code in one click and stops at any position where the source offers no common choice, which tells you where the real decision is.
-
Read why an option is missing
Codes the grammar rules out for your path appear in a rejected list with the reason: not tabulated for the current trigger value, not available with something you already picked, requires something you have not picked, or no meaning in the source at all. That last case is needs-source, and it blocks assembly rather than producing a plausible string.
-
Add option codes
Once every required position has a code, the option adders open: approvals, mounting brackets, displays, diagnostics, calibration and material certificates, bolting, conduit connectors, alarm levels, cleaning, and the rest. The 3051C table holds 122 option codes across 42 categories and the 3051SAL table holds 156 across 43. Each one carries its own availability conditions and its own page citation.
-
Check the segment table and the caution card
The segment table lists every code with its position, its meaning as resolved for your path, whether it is standard or special, and the page it came from. Anything the ordering table states only as sentence text lands in Restrictions this tool could not check. Read those against the order; they are the ones nobody catches until the instrument arrives.
-
Copy the RFQ block
The request for quote block is laid out like an Emerson configuration data sheet: manufacturer, platform, model number, source line, then the specification segment by segment with standard and special flagged, plus quantity, need-by date, tag, and notes. Copy it to the clipboard or open a mail draft you address yourself. Nothing is sent anywhere and no email address is collected.
Built For
- Writing a specification for a new differential pressure transmitter and needing the full 3051CD model string without a MyEmerson login or a call to a rep.
- Checking a quoted model number segment by segment before a purchase order goes out, to catch a housing or approval code that does not match the area classification.
- Working out which segments of a configuration are special rather than standard, because those are the ones that set the lead time.
- Configuring a 3051SAL level transmitter with a capillary seal system and needing the seal style branch, the connection sizes, and the capillary length carried in the same model string.
- Handing a distributor a complete configuration data sheet in one email instead of three rounds of clarifying questions.
- Training a new instrument tech on what each position of a Rosemount order code actually controls, using a live string rather than a static example.
- Comparing a 3051CD against a 3051CG for a level or flow application where the range column, not just the tag, decides which one is right.
Features & Capabilities
Guided position-by-position assembly
The builder walks the same audited grammar the decoder reads, in the other direction. Each position stays locked until every earlier position has a code, because the meaning of a later option can depend on an earlier one. The assembled string updates as you go.
Nothing is offered that the source does not tabulate
An option appears only where the ordering table gives a meaning for the current path. Where the table says a code is not valid for that path, the option is removed with the source note attached. Where the table gives no meaning at all, the result is needs-source and assembly is blocked rather than guessed.
On-screen decode-back verification
Once every position has a code, the assembled string is decoded through the shared decode engine and the decoded codes are compared against the codes you selected. If the decode is not clean, or if any segment disagrees, the string is not shown at all. The builder never emits a model number it cannot read back.
Standard versus special, flagged where it matters
Every segment in the result table is marked standard or special against the product data sheet. Special segments are the ones that drive lead time and the ones a distributor will ask about, so they carry that flag into the exports and into the request for quote block rather than being buried.
Restrictions the tool refuses to guess at
Parts of the ordering table state a compatibility limit only as sentence text, never broken out into codes. Those are collected into a caution card with the segment, the code, and the page, and the tool says plainly that it did not check them. That is a shorter list than the ones it does check, and it is the list that catches people.
Configuration-data-sheet-style RFQ block
The finished string comes with a plain-text request for quote laid out the way Emerson lays out a configuration data sheet, so an inside sales desk can read it without translation. Quantity, need-by date, tag, and free-text notes are yours to fill in, and everything stays on your machine.
Which platform: 3051C (CD, CG, CA) or 3051SAL
| Ordering fact | 3051C coplanar (CD / CG / CA) | 3051SAL scalable level |
|---|---|---|
| What it measures | Differential (CD), gage (CG), or absolute (CA) pressure. The measurement type code at position 1 selects the variant. | Liquid level, with the diaphragm seal system carried inside the same model number. Configuration type at position 2 is fixed at C. |
| Required positions before option codes | 8 | 11, plus a seal style position that opens a branch |
| What sets the pressure range column | Measurement type at position 1 (D, G, or A). Range 2 is minus 250 to plus 250 inH2O on D and G, and 0 to 150 psia on A. | Pressure module type at position 3 (D coplanar differential, G coplanar gauge, T in-line gauge). |
| Accuracy class in the model string | Not a position. It follows from the range and the options ordered. | Position 1: code 1 Ultra at 0.055 percent of span with 150:1 rangedown, code 2 Classic at 0.065 percent of span with 150:1 rangedown. |
| Output protocols on offer | A HART 4-20 mA, F FOUNDATION Fieldbus, W PROFIBUS PA, X WirelessHART, M low power 1-5 Vdc HART. | A HART 4-20 mA, F FOUNDATION Fieldbus (requires a Plantweb housing), X WirelessHART (requires a wireless Plantweb housing and an intrinsically safe approval). |
| Housing position | Housing material at position 8: aluminium or SST, NPT or M20 conduit entry, engineered polymer for wireless only. | Housing style at position 6 as a two-character code: Plantweb, wireless Plantweb, or junction box, in aluminium or SST. |
| Seal handling | A seal assembly is an option code (assemble to one or two Rosemount seals). The seal itself is a separate 1199 or 1299 model string. | Nine seal style branches (FF, EF, RF, PF, FC, RC, RT, SC, SS), each with its own positions for high side connection, low side connection or capillary inner dimension, capillary length, and seal fill fluid. |
| Option codes tabulated | 122 codes across 42 categories | 156 codes across 43 categories |

Assumptions
- Option codes, meanings, page citations, and compatibility metadata come from the audited ToolGrit rosemount-3051-decoder data set, copied into this app with a provenance header.
- 3051C rows come from Emerson product data sheet 00813-0100-4001 Rev WG, October 2025, pages 7 to 18.
- 3051SAL rows come from Emerson product data sheet 00813-0100-4801 Rev UW, April 2026, pages 101 to 135.
- A code is offered only where the source table gives a meaning for the current selection path. Where the table says a code is not valid for that path, or gives no meaning at all, the code is withheld and assembly is blocked instead of guessed.
- The assembled string is decoded back through the shared decode engine before it is shown. A string that does not read back cleanly, segment for segment, is not shown at all.
- A starred option is one the product data sheet flags as common. Starred is a sourcing and lead-time signal, not a recommendation for your process.
- The model number describes ordered hardware and options. It does not describe calibrated lower and upper range values, damping, alarm direction, HART revision, network setup, or installed condition.
Limitations
- Coverage is the 3051C platform (3051CD differential, 3051CG gage, 3051CA absolute) and the 3051SAL scalable level platform only. It does not cover 3051T, 3051L, 3051H, 3051CF, 3051S SuperModule variants, or separate 1199 and 1299 seal model strings.
- The assembled string is a model number, not an Emerson quote. Availability, price, lead time, and regional option support are not modelled here at all.
- Some options state a compatibility limit only as sentence text in the ordering table. Those sentences are not broken out into codes, so the tool does not check them and does not guess what they mean. It lists them for you to read against the order.
- It does not confirm that a configuration is right for your process. Wetted material compatibility, overpressure and static pressure limits, fill fluid temperature limits, and the pressure range the application actually needs are engineering decisions, not code lookups.
- Hazardous-area approval codes are assembled from the ordering table. They are not verified against a certificate or against the authority having jurisdiction, and an order code is not a certificate.
- It does not assemble a diaphragm seal model string. For a seal assembly, the 1199 or 1299 model string is a separate exercise.
- Page citations point at the product data sheet revision named in the source line, not at whatever revision is current on the day you read this. A newer revision can add, move, or withdraw an option code.
- It does not carry configuration data: lower and upper range values, damping, alarm and saturation direction, output direction, HART revision, or tagging content all live on the Emerson configuration data sheet, not in the model number.
