Emerson Rosemount 3051TG Differential Pressure Transmitter with Flange
The Emerson Rosemount 3051TG Differential Pressure Transmitter with Flange Connection is a high-performance instrument engineered for precise and reliable measurement of differential pressure in industrial environments. Designed to meet the demands of critical applications such as level, flow, and pressure monitoring, this transmitter combines advanced sensor technology, robust flanged design, and digital communication protocols to deliver exceptional accuracy and operational efficiency. Its integration of Coplanar™ sensor architecture and corrosion-resistant materials ensures long-term reliability in harsh conditions, making it ideal for sectors like oil and gas, chemical processing, power generation, and water/wastewater management.
Core Technical Performance and Design
The 3051TG Differential Pressure Transmitter offers a wide measurement range from 0.5 inH2O to 4,000 psi (12.7 mmH2O to 27,580 kPa), enabling it to handle low-pressure and high-pressure applications with equal precision. Its ±0.075% of span accuracy (upgradable to ±0.04%) ensures compliance with industry standards for custody transfer and process control. The transmitter supports multiple output signals, including 4-20 mA with HART® 7, FOUNDATION Fieldbus, and PROFIBUS PA, ensuring seamless compatibility with PLCs, DCS, and SCADA systems. Powered by 10.5-42 V DC (loop-powered for 4-20 mA models), it operates reliably across extreme ambient temperatures ranging from -40°C to +85°C (-40°F to +185°F) and responds to process changes in under 2 seconds.
The flanged connection design adheres to international standards such as ANSI, DIN, and JIS, ensuring compatibility with diverse piping systems and simplifying installation. The wetted materials include 316L Stainless Steel, Hastelloy C-276, Monel 400, or Tantalum, providing excellent resistance to corrosion, oxidation, and aggressive media. This makes the 3051TG suitable for sour service environments (compliant with NACE MR0175) and applications involving acidic or saline fluids.
Advanced Features and Communication Protocols
Equipped with Coplanar™ sensor technology, the 3051TG eliminates impulse lines, reducing maintenance in slurry or viscous media applications. Its IP66/IP67-rated aluminum or stainless steel enclosure protects against dust, moisture, and mechanical impacts, while the sensor's rugged construction resists vibration (2g RMS) and shock (50g, 11 ms).
Communication is streamlined via HART® 7, FOUNDATION Fieldbus, or PROFIBUS PA, enabling remote configuration, calibration, and diagnostics using tools like the Emerson Field Communicator or AMS Device Manager. These protocols support real-time monitoring of sensor health, predictive maintenance alerts, and data integration into enterprise-level systems. For safety-critical applications, the transmitter meets SIL 2 (IEC 61508) standards and is certified for use in ATEX/IECEx Zone 0/1/21/22 hazardous areas.
Industry-Specific Applications
Oil & Gas: Crude oil pipeline pressure monitoring, tank overpressure protection, and LNG liquefaction units.
Chemicals: Reactor level control, acid storage tanks, and multiphase flow measurement in corrosive environments.
Power Generation: Boiler drum level monitoring, condensate recovery, and steam pressure measurement in high-vibration settings.
Water/Wastewater: Open-channel flow control, clarifier level monitoring, and slurry handling with flanged piping systems.
Optional Accessories and Compliance
Enhance functionality with:
Remote Seal Kits for isolating the transmitter from extreme temperatures or corrosive media.
Local Display Modules (LCD or graphical) for real-time pressure and level readouts.
NIST-Traceable Calibration Certificates for regulatory compliance.
The 3051TG complies with ATEX/IECEx for explosive atmospheres, Marine approvals (DNV GL, ABS, LR) for offshore installations, and RoHS Directive 2015/863 for environmental compliance.
