Emerson Rosemount 3051TG HART 4-20mA Pressure Transmitter

The Emerson Rosemount 3051TG is an in-line pressure transmitter designed for precise gauge pressure measurement, serving as an industry standard for reliable performance in industrial applications. Combining proven sensor and electronics technologies with a single isolator design, it offers absolute and gauge pressure measurements from 0.3 to 10,000 psi (with extended ranges up to 20,000 psi for specific configurations).

Its compact in-line design allows direct connection to processes, simplifying installation and reducing costs. Equipped with HART communication (4-20 mA with digital signal) and a range of diagnostics, it integrates seamlessly into control systems, making it ideal for harsh environments and safety-critical applications.

• High Accuracy and Rangeability: Boasts accuracy of 0.5% FS and 1% FS, with a rangedown of up to 150:1, ensuring precise measurements across a wide pressure spectrum (1-600 bar for the 3051TG3A2B21AB4 model).
• Flexible Communication: Supports 4-20 mA with HART protocol, WirelessHART®, FOUNDATION fieldbus, PROFIBUS, and low-power 1-5 Vdc HART, enabling versatile integration into digital and analog control systems.
• Robust Construction: Features 316L stainless steel and Hastelloy C process isolation diaphragms, with filling fluids (silicon oil, inert oil) for compatibility with diverse media. A single isolated diaphragm design enhances durability.
• Advanced Diagnostics: Includes basic diagnostics and Loop Integrity monitoring; optional Power Advisory (Option Code DA0) proactively detects degraded electrical loop integrity, reducing downtime.
• Safety Certifications: SIL 2/3 certified to IEC 61508 by an independent third party, with additional approvals (NSF, NACE®, hazardous location ratings) for safety-critical and corrosive environments.
• User-Friendly Setup: Equipped with a Local Operator Interface (Option Code M4) featuring straightforward menus and built-in configuration buttons, simplifying on-site commissioning and calibration.
• Wide Operating Range: Functions in temperatures from -20 to 80°C, with maximum working pressures of 16MPa, 25MPa, or 40MPa, adapting to extreme process conditions.
