Emerson Rosemount 3051TG Stainless Steel Pressure Transmitter
The Emerson Rosemount 3051TG Stainless Steel Pressure Transmitter is a high-performance solution engineered for precise gauge pressure measurement in demanding industrial environments. Designed to deliver exceptional accuracy, durability, and versatility, this transmitter is ideal for applications in oil and gas, chemical processing, power generation, HVAC systems, and water/wastewater treatment. By integrating advanced sensor technology, corrosion-resistant stainless steel construction, and digital communication protocols, the 3051TG ensures reliable data acquisition and seamless integration into modern process control systems.
Core Technical Performance
The 3051TG offers an extensive pressure range from 0.5 inH2O to 4,000 psi (12.7 mmH2O to 27,580 kPa), catering to both ultra-low and high-pressure applications. Its ±0.075% of span accuracy (with an optional ±0.04% upgrade) ensures compliance with stringent industry standards, including API MPMS Chapter 5.6 for custody transfer. The transmitter supports multiple output signals-4-20 mA with HART® 7, FOUNDATION Fieldbus, and PROFIBUS PA-enabling compatibility with PLCs, DCS, and SCADA systems. Powered by 10.5-42 V DC (loop-powered for 4-20 mA models), it operates reliably in extreme ambient temperatures ranging from -40°C to +85°C (-40°F to +185°F) and responds to process changes in under 2 seconds.
Innovative Design and Durability
The 3051TG features Coplanar™ sensor technology, which eliminates impulse lines and minimizes maintenance in challenging environments involving corrosive fluids or viscous media. Its 316L Stainless Steel wetted materials provide excellent resistance to oxidation, acids, and chlorides, making it suitable for harsh chemical environments, offshore platforms, and food-processing facilities. Optional materials like Hastelloy C-276, Monel 400, or Tantalum further enhance compatibility with aggressive media. The transmitter's IP66/IP67-rated aluminum or stainless steel enclosure protects against dust, moisture, and mechanical impacts, while its sensor design resists vibration (2g RMS) and shock (50g, 11 ms), ensuring long-term reliability in extreme conditions.
Advanced Communication and Diagnostics
Equipped with HART® 7, FOUNDATION Fieldbus, or PROFIBUS PA, the 3051TG enables remote configuration, calibration, and diagnostics via tools like Emerson Field Communicator or AMS Device Manager. These protocols support real-time monitoring of sensor health, process anomalies, and predictive maintenance alerts, reducing unplanned downtime. 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: Pipeline integrity monitoring, tank overpressure protection, and wellhead pressure control in explosive atmospheres.
Chemicals: Reactor vessel pressure management, acid storage tanks, and solvent handling systems requiring corrosion resistance.
Power Generation: Boiler pressure measurement, turbine lube oil monitoring, and condensate recovery in high-vibration environments.
HVAC Systems: Compressor discharge pressure, filter differential pressure, and chiller performance optimization with low-pressure sensitivity.
Global Certifications and Compliance
The 3051TG Series complies with international standards:
ATEX/IECEx for explosive atmospheres.
NACE MR0175 for sour service in oil and gas.
Marine approvals (DNV GL, ABS, LR) for offshore installations.
RoHS Directive 2015/863 for environmental compliance.
Optional Accessories
Enhance functionality with:
Remote Seal Kits for isolating the transmitter from extreme temperatures or corrosive media.
HART Modem for wireless configuration in hazardous areas.
Local Display Modules (LCD or graphical) for real-time pressure readouts.
NIST-Traceable Calibration Certificates for regulatory compliance.
