Emerson Rosemount 3051TG Pressure Transmitter

Core Performance & Industrial Application

The Emerson Rosemount 3051TG is an in-line gage pressure transmitter from the proven 3051 family for industrial process pressure measurement.

It converts gauge pressure into a standard 4-20mA HART signal for DCS, PLC or pressure recorder acquisition.

Reference accuracy reaches ±0.04% of span with 10-year stability of 0.2% of upper range limit.

It supports HART digital communication, local LCD display and advanced loop integrity diagnostic functions.

It is SIL 2/3 certified per IEC 61508 and suitable for safety-related pressure monitoring loops.

It is widely used as spare replacement in chemical, oil & gas, power and water process control systems.
