More Information

Overview Manuals Applications Connectivity Programming Safety

Features:

  • The completed order string preserves the process connection, mounting, indication, communication, and approval configuration.
  • The existing configuration and alarm behavior should be captured before removing power or process pressure.
  • The atmospheric reference and enclosure entries must remain protected without blocking pressure equalization.
The ordering reference denotes a fully configured gauge-pressure transmitter with defined mechanical and display options; only documented selections are treated as included.

Its service objective is gauge-pressure measurement in an established wired loop. The configured package supports Range 3 gauge service, local indication, and HART Revision 5 communication.

A like-for-like review covers the threaded connection, bracket, display, enclosure entry, atmospheric reference, HART host revision, and certification. Check the documented process connection, bracket, and enclosure entry against the installed unit.

Availability is subject to Apter Power inventory and sourcing confirmation.

  • Provides gauge-pressure feedback on process skids that retain the documented process connection and mounting hardware.
  • Monitors pump or compressor duty where local indication assists maintenance and operator checks.
  • Supports control loops that require the installed communication revision and alarm behavior to remain unchanged.
  • The wired loop provides the process measurement and the service path defined by the installed electronics.
  • Cable shields and protective earth follow the project wiring drawing rather than improvised field practice.
  • Reconnect approval requires a successful host readback from this configured gauge assembly.
  • Tag, damping, alarm direction, and output mapping are retained in the asset configuration file.
  • A service tool reads the existing setup before replacement hardware is introduced.
  • Download acceptance includes a controlled input check on this configured gauge assembly.
  • The process connection is treated as pressurized until isolation, venting, and verification are complete.
  • Approved grounding and enclosure closure are restored before energization.
  • Alarm action is proven at the host before in-line gauge measurement with local indication resumes.
Description
3051GP3A2B21AB4M5HR5 designates a fully configured gauge-pressure transmitter with defined mechanical and display options for an installed Rosemount 3051 measurement point. The device record preserves the selected assembly details.

Its process role is gauge-pressure measurement in an established wired loop. It combines local pressure indication with host-system measurement for a documented installation.

For like-for-like service, reconcile the threaded connection, bracket, display, enclosure entry, atmospheric reference, HART host revision, and certification. Complete functional verification after the mechanical and electrical checks pass.
