Rosemount 3051 Decoder
Paste a supported 3051SAL, 3051CD, 3051CG, or 3051CA model code and review page-cited PDS rows with order, seal, certification, configuration, and safety gaps kept visible.
A grammar-driven reference for supported Rosemount 3051 pressure transmitter model codes. The 3051SAL Scalable Level Transmitter (PDS 00813-0100-4801 Rev UW April 2026) and the 3051C Coplanar pressure transmitter family covering 3051CD differential, 3051CG gage, and 3051CA absolute (PDS 00813-0100-4001 Rev WG October 2025) are supported. Type or paste a model code and the tool walks each local parser position in order, resolves it against the cited PDS page, and surfaces compatibility/source prompts that still require current Emerson documents, configurator or representative review, product certificate, configuration data sheet, QSG/manual, process conditions, and qualified review before ordering, installation, or commissioning. For 3051SAL, the seal style branch at position 12 expands into FF, EF, RF, PF, FC, RC, RT, SC, or SS sub-tables. Additional options after the required positions parse via longest match against local approval, display, mounting, calibration, certification, and diagnostic rows. Codes not found in the supported source rows are flagged as unknown rather than guessed.

Pick or Paste a Model Code
Type the full ordering string in the input field, or click one of the example chips to load a worked-out string. Spaces, slashes, hyphens, and commas are all treated as separators, so the tool reads "3051SAL1CD2AA1A2020DFF71CA00/K5/B4/Q4" the same as "3051SAL 1 C D 2A A 1A 2 0 2 0 0 D FF 7 1 CA 0 0 / K5 / B4 / Q4". The tool is case-insensitive on input but every output is shown in uppercase to match the PDS.
-
Read the Family Banner
The first card after decoding shows which family the prefix matched (3051SAL or 3051C) and which Emerson Product Data Sheet revision was used as the source. If the family was not recognized, the tool says so and links to the supported prefixes rather than guessing. For 3051C, all three measurement types (D differential, G gage, A absolute) share the same ordering matrix and the first position selects the variant.
-
Walk the Required Positions
Each row shows the position number, the raw code from the input, the position name, the plain-English meaning, the confidence label, and the source page. Stars (★) mark Emerson standard offerings that ship faster. Context-dependent positions (Pressure range on 3051SAL depends on Pressure module type, Pressure range on 3051C depends on Measurement type, position 8 and 9 on 3051SAL depend on Seal system type) show which context was applied so the user can see how the meaning was resolved.
-
Walk the Seal Style Branch (3051SAL only)
After the eleven required positions, 3051SAL branches into a seal style: FF flush flanged, EF extended flanged, RF remote flanged, PF pancake, FC flush flanged with RTJ gasket, RC remote flanged with RTJ, RT remote threaded, SC hygienic Tri-Clamp, or SS hygienic tank spud. The tool shows the seal name, the branch description, and each sub-position with its own source page. EF six-inch extensions only ship with SST materials, FC only ships with high-pressure ASME flanges, and SC and SS are limited to hygienic process connections.
-
Read the Additional Options
Options after the required positions parse by longest match. Q4 cal cert, QT IEC 61508 SIL certification, K5 FM XP/DIP/IS approval, B4 SST mounting bracket, M5 Plantweb LCD, T1 transient terminal block, WR3 / WR5 extended warranty, and so on. Options are grouped by category in the output so it is easy to spot which Approvals, Brackets, or Calibration certs are on the order.
-
Check Compatibility Warnings
The decoder runs local rules drawn from supported PDS footnotes: wireless output (X) requires intrinsically safe approvals, FOUNDATION Fieldbus (F) requires Plantweb housing, FM/CSA combination approvals are not available with M20 or G1/2 conduit entry, EF 6-inch extension only with SST, drain/vent valve FV is required for Seal system type C or D with DP module D, and so on. These warnings are review prompts, not product-certification, orderability, hazardous-area, seal, or installation approval.
-
Read Field Notes and Cross-References
The field notes section captures domain knowledge that the matrix does not state explicitly: tantalum diaphragm temperature limits in chloride service, hygienic clamp MWP being limited by the customer-supplied clamp rating, wireless and IS planning, fill fluid behaviour in vacuum. Cross-references jump straight to related ToolGrit tools (motor nameplate decoder, wire sizing, voltage drop, panel load) and back to the authority guide.

Export the Decoded Report
Use the PDF export for a reference review record that lists decoded rows, parser warnings, source warnings, residual gaps, and cross-references. Use the CSV export for spreadsheet review. Share the URL to send the same normalized decode to a coworker without re-typing the code.

Features & Capabilities
Two Families, Three Variants
Supports 3051SAL Scalable Level Transmitter from PDS 00813-0100-4801 Rev UW April 2026 (eleven required positions plus a branching seal style at position 12), and 3051C Coplanar pressure transmitter from PDS 00813-0100-4001 Rev WG October 2025 (eight required positions plus appended additional options). 3051CD differential, 3051CG gage, and 3051CA absolute all share the 3051C matrix and select the variant at position 1.
Grammar-Driven, Not a Flat Lookup
A real 3051 model code mixes required model components, context-dependent meanings, seal subassemblies, and appended options. The decoder is built around a grammar that separates these layers. Required positions consume fixed-width codes left-to-right. Seal style at SAL position 12 forks the parser into a branch of seal-specific positions. After the required positions and seal branch, the remaining string parses against an option-code dictionary using longest match. This is why a tag with options in different order, with or without slashes, still decodes cleanly.
Source-Cited Local Rows
Supported local meanings carry the PDS page used by the parser, and parser compatibility checks carry the PDS page where the footnote was mapped. Page citations are source pointers, not proof of current orderability, certification, process compatibility, pressure rating, seal suitability, or installed configuration.
Honest About Unknown Codes
When a code is not in the source PDS for the matched family, the decoder reports it as "Unknown - code not listed" rather than guessing. The decoder errs on the side of admitting it does not know.
Context-Dependent Positions Resolved Automatically
Pressure range URL on 3051SAL changes by Pressure module type (Coplanar DP, Coplanar Gauge, In-line Gauge). Pressure range on 3051C changes by Measurement type (Differential, Gage, Absolute). High side connection and Low side connection on 3051SAL change by Seal system type (direct mount, remote mount with capillary, Tuned-System, Balanced). The decoder reads the trigger position first, then resolves the dependent meaning, and shows "Context applied: Pressure module type = D" inline so the user sees how the resolution was made.
Compatibility Review Prompts
A local exclusion-rules engine flags wireless (Output X) without an intrinsically safe approval code (rule X1), FOUNDATION Fieldbus (Output F) without Plantweb housing (rule X2), tantalum diaphragms (CC, DC) with thin-diaphragm option SC (rule X3), EF six-inch extension on non-SST materials (rule X4), FM and CSA combo approvals on M20 or G1/2 conduit entry (rule X6), QT safety cert on FF or X output (rule X7), missing drain/vent valve FV on Seal system C or D with DP module (rule X9), UltraTherm 805 fill fluid without a thermal range expander (rule X10), and several more. Treat these as PDS review prompts only.
Plain-English Summary
A successful decode produces a one-line plain-English summary for review notes. It is not a purchase requisition, order approval, product certificate, hazardous-area approval, SIL approval, pressure-rating approval, or commissioning record.
Field Notes That the PDS Does Not Print
Each family carries a list of caveats drawn from field experience and from PDS context that does not survive a quick reading: tantalum diaphragm temperature failure modes in chloride service, hygienic clamp MWP being limited by the customer-supplied clamp, wireless approval planning, derating above 185 °F ambient on direct-mount seals, the cold-temperature option matrix on 3051CD, and the trade-off between direct mount and remote mount with capillary. These are written like a senior planner walking a junior planner through the trade-offs.
Cross-References to the Rest of ToolGrit
Each decode includes a cross-reference panel pointing at related planning tools. Those links do not verify loop wiring, panel capacity, hazardous-area suitability, process compatibility, or installed configuration; they are prompts for broader review.
PDF and CSV Export
PDF export uses the shared ToolGrit programmatic PDF generator and includes source/safety boundaries and residual gaps. CSV export packages the same review fields for spreadsheet use. Share-URL encoding lets a coworker open the same normalized decode in their browser without retyping the code.
Light and Dark Mode, Mobile-Friendly
Standard ToolGrit light and dark theme with WCAG AA contrast throughout. The decoded output collapses cleanly to mobile at 375 px viewport without horizontal scrolling. The Plain-English summary is a screen-reader-friendly aria-live region so accessibility tools announce the decoded result when the input changes.
