Overview Manuals Applications Interoperability Configuration Certifications

Features:

  • The scalable coplanar platform integrates with compatible manifolds, primary elements, and seal solutions.
  • The sensing module and electronics configuration must be treated as a matched assembly during service planning.
  • Final environmental capability follows the completed enclosure, electronics, display, and approval configuration.
This order identifies a scalable coplanar differential-pressure transmitter on the Rosemount 3051S platform; the physical nameplate governs the exact assembly supplied.

Its assigned work is low differential-pressure measurement with modular process and system integration. Performance class 2 identifies the Classic measurement class for this Range 1 SuperModule configuration.

Before installation, verify the performance class, coplanar hardware, communication option, housing, display, diagnostics, process materials, and approvals. Replacement planning should preserve the SuperModule identity, process interface, and electronics compatibility.

Availability is subject to Apter Power inventory and sourcing confirmation.

  • Supports low differential-pressure measurement on process equipment using compatible coplanar manifolds.
  • Integrates with assembled DP flow solutions when the selected primary element and calculation method are documented.
  • Provides level measurement through impulse piping or approved seal systems selected for the vessel and process fluid.
  • Maintenance tools require support for the protocol revision delivered with the completed configuration.
  • Mechanical accessories are checked against the exact sensing-module and flange arrangement.
  • The control database preserves the scaling and failure action assigned to this scalable low-range coplanar assembly.
  • Lower and upper range values remain inside the capability of the selected sensing module.
  • The transmitter tag and units are compared with the control-system database before download.
  • Trim history is retained so maintenance changes can be distinguished from process effects during integrated low differential-pressure measurement.
  • A family data sheet does not substitute for the certification marks on the delivered unit.
  • Entity parameters and wiring restrictions are taken from the applicable approval document.
  • Grounding and unused-entry plugs remain consistent with the certified construction used for integrated low differential-pressure measurement.
Description
3051S2CD1A is a scalable coplanar differential-pressure transmitter on the Rosemount 3051S platform in the Rosemount 3051S range. The complete nameplate is the controlling record for the supplied assembly.

The installed duty is low differential-pressure measurement with modular process and system integration. Its SuperModule architecture separates the pressure-sensing assembly from selectable electronics and communication options.

Before replacement, confirm the performance class, coplanar hardware, communication option, housing, display, diagnostics, process materials, and approvals. Record the final comparison in the maintenance documentation.

FAQS

The following is a list of questions commonly asked by our customers. Please contact us if you have a question about our process that is not answered below.
Which scalable-platform selections remain open in the partial code 3051S2CD1A?
Performance class, electronics, communication, housing, process materials, indication, diagnostics, and approvals require confirmation from the full order code.
What Coplanar hardware must remain compatible with 3051S2CD1A?
Match the coplanar manifold, flange accessories, sealing surfaces, sensing module, and host communication used by the installed assembly.
How can 3051S2CD1A support a low-range differential measurement?
It is appropriate for low differential service only when the process span, static pressure, impulse system, and selected performance class are validated.
Which commercial scope should be stated when requesting 3051S2CD1A?
State the complete nameplate code, required condition, quantity, destination, delivery target, and whether a matched assembly is required.
May another 3051S2CD range be inserted in place of 3051S2CD1A without reranging the application?
A different sensor range changes the calibrated capability and cannot be inserted without application review, reranging, and acceptance testing.
What official 3051S data should be reviewed for 3051S2CD1A?
Use the Rosemount 3051S product data sheet, reference manual, and documentation for the installed manifold or seal system.
