ROSEMOUNT 3051TG1A2B21BB4K5M5T104 Gauge Pressure Transmitter

Overview

The ROSEMOUNT 3051TG1A2B21BB4K5M5T104 is a direct mount gauge pressure transmitter from the Rosemount 3051T series under Emerson Automation. The ROSEMOUNT 3051TG1A2B21BB4K5M5T104 adopts high-performance capacitive sensing technology and supports HART 4–20mA signal output for accurate gauge pressure measurement of gas, liquid and steam in process pipelines and pressure vessels. The ROSEMOUNT 3051TG1A2B21BB4K5M5T104 is equipped with local LCD display for on-site reading and parameter configuration, and can be calibrated and diagnosed via the 475 field communicator and AMS Device Manager software. It is widely stocked as spare pressure transmitter for oil & gas, chemical, power plant and water treatment DCS and PLC control systems.

Features

The ROSEMOUNT 3051TG1A2B21BB4K5M5T104 achieves high measurement accuracy and stable long-term drift performance, with built-in temperature compensation and static pressure compensation logic to reduce measurement error under changing working conditions. The ROSEMOUNT 3051TG1A2B21BB4K5M5T104 integrates comprehensive self-diagnosis functions including sensor fault, over-range alarm and wiring fault detection, and supports burst mode and multi-variable reading through HART protocol. The ROSEMOUNT 3051TG1A2B21BB4K5M5T104 is fitted with 316L stainless steel process wetted parts, and supports a wide range of explosion-proof and intrinsic safety certifications for hazardous classified areas. The ROSEMOUNT 3051TG1A2B21BB4K5M5T104 adopts standard 1/2-14 NPT process connection and can be directly mounted on the process tapping point without extra manifold assembly, following the original pinout definition for direct replacement of the same 3051TG series transmitters.

Specs

Device Type: Gauge pressure transmitter Model: ROSEMOUNT 3051TG1A2B21BB4K5M5T104 Series: 3051T Sensor Type: Capacitive sensor Output Signal: 4–20mA with HART digital protocol Process Connection: 1/2-14 NPT female Wetted Material: 316L stainless steel Display: Local LCD digital display Configuration Tool: 475 field communicator, AMS Device Manager Power Supply: 10.5–42.4 V DC Protection Grade: IP66 / IP67 Operating Temperature: -40°C ~ +85°C Application: Chemical plant, oil & gas pipeline, thermal power DCS, water treatment, hazardous area pressure monitoring

Principle

The ROSEMOUNT 3051TG1A2B21BB4K5M5T104 guides the process pressure into the internal capacitive sensor cavity. The sensor converts pressure changes into capacitance variation signals, and the internal circuit converts the capacitance signal into standardized 4–20mA analog output superimposed with HART digital data. The DCS or PLC system reads the pressure value through the signal cable. The ROSEMOUNT 3051TG1A2B21BB4K5M5T104 continuously monitors sensor health and process status, and triggers fault indication and alarm when abnormal conditions occur.

Applications

The ROSEMOUNT 3051TG1A2B21BB4K5M5T104 is used for real-time gauge pressure monitoring of process pipelines, tanks and equipment in chemical, oil & gas, power and water treatment automation systems. It serves closed-loop pressure control and safety interlock for process control loops. The ROSEMOUNT 3051TG1A2B21BB4K5M5T104 applies to spare stock and emergency replacement of legacy Rosemount 3051TG pressure transmitter assemblies. It also supports instrument loop renovation, calibration and configuration migration projects.
