A decoder for supported Rosemount 3144P Temperature Transmitter model-code rows. The local parser reads the housing style, transmitter output, measurement configuration, current Rev TH X-well measurement-configuration rows, and option adders from Emerson PDS 00813-0100-4021 Rev TH. It is a reference prompt only: it does not replace the current Emerson configurator, quote, product-certification label, QSG/manual, configuration data sheet, live device configuration, sensor/pipe/X-well details, local code/AHJ review, or qualified instrumentation and safety review. Sensor type, range, span, damping, alarm levels, HART/Fieldbus setup, SIS proof, and X-well installation suitability are not proven by the model code alone.

Pro Tip: Rev TH moved X-well into measurement configuration codes 3 and 4 instead of the older PT option pattern. Treat those rows as a prompt to pull the current Emerson X-well/PDS/QSG/manual data for pipe size, pipe material/schedule, sensor assembly, mount design, insulation, process conditions, monitoring-only limits, and factory configuration. The decoder flags missing X-well rows, but it does not approve X-well for control, custody transfer, SIS, process accuracy, installation, or safe work.

How It Works

  1. Start with the 3144P prefix

    Begin the code with 3144P. The decoder then reads three required positions: housing style, output, and measurement configuration.

  2. Read the housing style

    Position 1 is a two-character housing code (D1-D9, D0): a field-mount dual-compartment housing in aluminum, stainless steel, or ultra-low-copper aluminum, with a specific conduit entry type (NPT, M20, PG13.5, or JIS).

  3. Read the output

    Position 2 is the output: A HART 4-20 mA or F FOUNDATION Fieldbus. The output gates which options are available; Fieldbus removes the HART-only feature set.

  4. Read the measurement configuration

    Position 3 can be single sensor (1), dual sensor (2), X-well assembly with sensor/mounting (3), or transmitter-only X-well capability (4) in the current Rev TH source. Dual-input modes still require the proper dual-sensor setup and qualified configuration review.

  5. Walk the option string

    Diagnostics, current X-well rows, performance, brackets, display, transient protection, software configuration, alarm levels, calibration, dual-input modes, custody, safety, shipboard, cold temperature, conduit connectors, HART revision, assemble-to, warranty, and approvals are matched by longest match where locally supported.

  6. Read the constraint warnings

    Warnings flag source conflicts and missing review prompts: X-well rows on the wrong lane, missing C1/HR7/X-well rows, Fieldbus-only control/diagnostics on a HART build, and dual-input modes without dual-sensor configuration.

  7. Note the sensor is configured separately

    The normal model code does not prove RTD/thermocouple type, range, span, damping, alarm levels, variable mapping, Fieldbus block setup, calibration, or installed wiring. Pull the Configuration Data Sheet or live device configuration.

  8. Export the prompt

    PDF, CSV, and share URL reproduce the decode plus warning boundaries; they are not an Emerson order, certificate, installation procedure, SIS approval, or commissioning record.

Built For

  • Reliability engineer confirming a dual-sensor 3144P (config 2) before promising Hot Backup or sensor drift detection on a critical temperature loop
  • Instrument tech decoding a 3144P nameplate to order a matching spare with the same housing and output
  • Project engineer checking a Rev TH X-well prompt still needs current Emerson X-well, pipe, sensor, and installation review
  • Planner confirming a Fieldbus 3144P order is not carrying HART-only options that will be rejected
  • Buyer spotting that a QT/SIS-looking row still needs the safety manual, FMEDA certificate, SIF basis, and functional-safety review
  • Specifier choosing between differential (U5), average (U6), and first-good (U7) dual-input modes and confirming the build is dual sensor
  • Estimator bulk-decoding 3144P codes from an instrument index

Features & Capabilities

Single, dual, and X-well rows

The measurement configuration position now includes single sensor, dual sensor, X-well assembly, and X-well-capable transmitter-only rows. The decoder flags missing source-review prompts for X-well and dual-input paths.

Rev TH X-well awareness

X-well measurement configuration 3/4 rows are decoded with C1/HR7 and pipe-mount prompts where locally supported, while the app keeps monitoring-only, process, and installation gaps visible.

HART-vs-Fieldbus feature gating

FOUNDATION Fieldbus output removes HART-only options and current X-well rows. Fieldbus-only and HART-only options are flagged against the wrong output, but final acceptance still belongs to current Emerson documents/configurator review.

Full dual-input mode coverage

Hot Backup (U1), drift alert warning/alarm (U2/U3), differential (U5), average (U6), first-good (U7), and two-independent (U4) are all decoded with their dual-sensor requirement enforced.

Sensor-not-in-code honesty

The decoder states that sensor type, range, and span are configured separately and points at the Configuration Data Sheet and assemble-to option.

Source-cited, boundary-labeled

Supported local rows carry PDS page pointers from 00813-0100-4021 Rev TH, February 2026, plus warnings that page citations do not prove orderability, certification, configuration, installation, or safe operation.

PDF and CSV export

PDF and CSV export the full decode with warnings and source-boundary notes.

Tripwire test suite

Canonical integrity, Rev TH X-well golden path, negative paths, source-page coverage, saved-state hydration, source-pointer uniqueness, report/PDF warning propagation, and summary snapshot tests run on every change.

Frequently Asked Questions

Do not decide that from this decoder. Current Rev TH X-well rows are measurement-configuration driven and need the current Emerson X-well/PDS/QSG/manual, pipe/sensor/mount/insulation/process facts, and qualified review. The app treats X-well as a source-review prompt, not control-loop, custody-transfer, SIS, process-accuracy, installation, or safe-work approval.
Hot Backup (U1) and the other dual-input modes (U2/U3 drift, U5 differential, U6 average, U7 first-good, U4 two-independent) all require the dual-sensor measurement configuration (position 3 = 2). A single-sensor build has nothing to fail over to or compare against. The decoder flags any U-mode on a single-sensor configuration.
Fieldbus (output F) removes HART-only rows such as DA1, C1, NAMUR alarm levels, custody-transfer rows, some drift-alert modes, HART safety certs, HART revision rows, and current X-well ordering rows. Fieldbus acceptance still requires current Emerson Fieldbus QSG/manual, host/AI-block/channel mapping, segment design, and qualified review.
No. As with the 644, the normal model code does not prove the configured sensor type, range, span, damping, alarm levels, variable mapping, or Fieldbus block setup. Pull the Configuration Data Sheet or live device configuration.
U5 reports differential temperature (sensor 1 minus sensor 2), U6 reports the average of the two sensors, and U7 reports the first good temperature (it uses sensor 1 and falls back to sensor 2 on a fault). U1 is Hot Backup (failover), U4 is two fully independent sensor readings, and U2/U3 add drift alerting in warning or alarm mode. All require the dual-sensor configuration.
Choose the 3144P when you need its dual-sensor feature depth (Hot Backup, differential/average/first-good modes, drift alerting), X-well surface measurement, or its tighter accuracy options. For the majority of plant temperature points, the 644 is the right, lower-cost choice. Both decode here, and both leave the sensor out of the model code.
Disclaimer: This decoder reads supported Rosemount 3144P model-code rows against cited public Emerson source pointers. Option availability, dual-sensor capability, X-well rows, diagnostics, and approval codes vary by PDS revision, and the model code does not prove configured sensor type, range, span, calibration, alarms, Fieldbus setup, SIS basis, hazardous-area installation, or X-well process suitability. Use this tool as a source-aware reference only; verify the final model number against the current Emerson PDS/configurator, product certification label, QSG/manual, project specification, local code/AHJ, and qualified instrumentation/safety review before ordering, installing, or commissioning. This is not an official Emerson configuration tool.
