Professional-grade Rosemount 3051TG3A2B21AB4E8M5Q4Q8S1HR7+1199WFC59AEFW71DA802 remote diaphragm seal offering -14.7 to 800 psi (-1.01 to 55.15 bar) [3051TG]; 0 to 800 psia (0 to 55.15 bar) [3051TA] capabilities alongside robust 4-20 mA with digital signal based on HART® Protocol.
The Rosemount 3051TG3A2B21AB4E8M5Q4Q8S1HR7+1199WFC59AEFW71DA802 is an integrated remote diaphragm seal solution engineered for demanding process environments where direct contact with the media is impractical or detrimental to measurement integrity. This assembly combines the proven 3051T in-line pressure transmitter with a purpose-matched 1199 series remote seal, delivering high-accuracy differential and absolute pressure sensing across a range of -14.7 to 800 psi (-1.01 to 55.15 bar) for gauge applications and 0 to 800 psia (0 to 55.15 bar) for absolute configurations. The 4-20 mA output, augmented by HART® Protocol digital communication, ensures seamless integration into existing distributed control systems (DCS) and asset management architectures, providing real-time process visibility and enabling predictive maintenance strategies.
Key Features & High-End Benefits
Remote Seal Flexibility for Process Isolation: The 1199WFC59AEFW71DA802 remote diaphragm seal isolates the transmitter from corrosive, viscous, or high-temperature process fluids. This configuration eliminates direct media contact, preventing clogging, crystallization, or sensor damage, thereby extending operational life and reducing unplanned downtime.
HART® Protocol for Advanced Diagnostics: The integrated digital signal based on HART® Protocol allows for simultaneous analog and digital communication. This enables remote configuration, loop diagnostics, and access to multivariable data such as temperature and sensor status. Operators gain actionable insights into seal health and process anomalies, facilitating proactive maintenance and minimizing process interruptions.
Material Compatibility (Code DA): The specified material construction (DA) provides robust resistance to a broad spectrum of aggressive chemicals and high-temperature environments. This metallurgical selection
