Overview Manuals Applications Connectivity Programming Standards

Features:

  • The long ordering code fixes the sensing assembly, mechanical selections, indication, and communication revision as one configuration.
  • A verified configuration export should be retained before removal so only validated settings are restored.
  • Enclosure integrity depends on correctly tightened covers, suitable cable glands, and intact sealing surfaces.
The ordering reference denotes a fully configured differential-pressure transmitter with a defined option package; only documented selections are treated as included.

Its service objective is low differential-pressure process measurement with documented HART integration. The configured package combines Range 1 differential measurement with HART Revision 5, local display, and FM approvals.

A like-for-like review covers the complete suffix set, manifold interface, bracket arrangement, display access, host revision, and certified installation details. Retain the original alarm action and certification identity when transferring the configuration.

Availability is subject to Apter Power inventory and sourcing confirmation.

  • Supports low-pressure-drop monitoring where the installed impulse system is kept symmetrical and free of blockage.
  • Provides a differential input for flow calculations after the primary element and host algorithm are confirmed.
  • Serves process level measurement when wet-leg, dry-leg, or seal arrangements are documented for the vessel.
  • The receiving input must match the completed transmitter output and configured failure direction.
  • Field polarity and available terminal voltage are verified with the loop connected.
  • Maintenance-tool support is confirmed before the low differential-pressure measurement channel is placed back in service.
  • Engineering units and calibrated endpoints are entered from the approved loop data sheet.
  • Zero adjustment is completed only after installation stress and process reference conditions have stabilized.
  • The restored parameter set is proven against the host indication used for low differential-pressure measurement.
  • The completed ordering code determines which electrical and pressure approvals apply to the assembly.
  • Process-wetted hardware is selected to the project piping and material specification.
  • Compliance records retain the verified suffixes, manifold, display, host revision, and certification for this configured DP option package.
Description
3051DP1A22A1AB4M5K5HR5 designates a fully configured differential-pressure transmitter with a defined option package for an installed Rosemount 3051 measurement point. The device record preserves the selected assembly details.

Its process role is low differential-pressure process measurement with documented HART integration. It supports controlled ranging and device-status access without changing the established process connection.

For like-for-like service, reconcile the complete suffix set, manifold interface, bracket arrangement, display access, host revision, and certified installation details. Complete functional verification after the mechanical and electrical checks pass.

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 field records should be captured before removing 3051DP1A22A1AB4M5K5HR5?
Capture the full nameplate, device tag, range values, damping, alarm direction, trim status, and installed option photographs.
How is HART revision compatibility evaluated for 3051DP1A22A1AB4M5K5HR5?
Check the maintenance host against the configured HART revision and confirm the receiving loop preserves the required signal action.
What differential measurement role can 3051DP1A22A1AB4M5K5HR5 serve in a process unit?
Use it only in a differential-pressure installation whose manifold, impulse piping, process media, and operating span match the completed order.
Which requested-delivery details are relevant to locating 3051DP1A22A1AB4M5K5HR5?
Supply the complete model string, condition preference, quantity, destination, delivery target, and photographs of the mounted assembly.
Why must every documented option be compared before replacing 3051DP1A22A1AB4M5K5HR5?
Each option affects the delivered configuration, so replacement review must cover sensing, process, enclosure, indication, and approvals.
What evidence should an installer retain after commissioning 3051DP1A22A1AB4M5K5HR5?
Keep the correct Rosemount product data sheet, HART reference manual, loop drawing, and saved configuration file with the asset record.
