Emerson Rosemount 3051S2CG Differential Pressure Transmitter - Product Description
The Emerson Rosemount 3051S2CG Differential Pressure Transmitter is a high-precision instrument engineered for reliable measurement of differential pressure in gas, liquid, and steam applications across diverse industrial sectors. Designed to deliver exceptional accuracy, durability, and ease of integration, this transmitter is ideal for critical processes in oil and gas, chemical, power generation, HVAC, and water/wastewater industries. Combining advanced sensor technology with digital communication protocols, the 3051S2CG ensures optimal process control, safety, and operational efficiency.
Core Technical Performance
The 3051S2CG offers an extensive pressure range from 0.5 inH2O to 4,000 psi (12.7 mmH2O to 27,580 kPa), enabling it to handle both low-pressure and high-pressure applications. Its ±0.04% of span accuracy (with an optional ±0.025% upgrade) ensures precise measurements vital for custody transfer, reactor monitoring, and steam flow control. The transmitter supports multiple output signals, including 4-20 mA with HART® 7, FOUNDATION Fieldbus, and PROFIBUS PA, ensuring seamless integration 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 3051S2CG features Coplanar™ sensor technology, which eliminates impulse lines and minimizes maintenance in challenging environments involving corrosive fluids or viscous media. Available with wetted materials such as 316L Stainless Steel, Hastelloy C-276, Monel 400, or Tantalum, the transmitter withstands aggressive chemicals and sour service applications (compliant with NACE MR0175). Its IP66/IP67-rated aluminum or stainless steel enclosure protects against dust, moisture, and mechanical impacts, while the sensor's rugged design resists vibration (2g RMS) and shock (50g, 11 ms). This durability ensures long-term performance in harsh conditions, such as offshore platforms, chemical plants, and power stations.
Advanced Communication and Diagnostics
Equipped with HART® 7, FOUNDATION Fieldbus, or PROFIBUS PA, the 3051S2CG 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: Crude oil pipelines, natural gas processing, and LNG liquefaction units.
Chemicals: Reactor pressure monitoring, solvent handling, and multiphase flow measurement.
Power Generation: Steam pressure measurement, condensate recovery, and turbine protection.
HVAC Systems: Airflow and filter differential pressure monitoring for energy efficiency.
Global Certifications and Compliance
The 3051S2CG Series complies with international standards:
ATEX/IECEx for explosive atmospheres.
Marine approvals (DNV GL, ABS, LR) for offshore installations.
EMC immunity (IEC 61326-1) for electrical noise resistance.
RoHS Directive 2015/863 for environmental compliance.
Optional Accessories
