Professional-grade Rosemount 3051TG3A2B21BB4E8M5P1Q4Q8S1Q15+1199WDE15AFFWG2DBA9TG 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 3051TG3A2B21BB4E8M5P1Q4Q8S1Q15+1199WDE15AFFWG2DBA9TG represents a pinnacle of precision pressure measurement for demanding industrial processes. This integrated Remote Diaphragm Seal (RDS) system combines the proven 3051T pressure transmitter with a 1199 series diaphragm seal, engineered specifically for applications requiring isolation from corrosive, viscous, or high-temperature process media. The unit delivers a 4-20 mA output with digital signal based on HART® Protocol, ensuring seamless integration into existing plant control architectures. With a measurement range spanning -14.7 to 800 psi (-1.01 to 55.15 bar) for the 3051TG variant and 0 to 800 psia (0 to 55.15 bar) for the 3051TA, this assembly provides exceptional versatility for both gauge and absolute pressure monitoring in critical process streams.
Key Features & High-End Benefits
Alloy C-276 Wetted Materials: The use of Hastelloy C-276 for all wetted components delivers superior corrosion resistance against aggressive chemicals, including chlorides, sulfuric acid, and hydrogen sulfide. This metallurgical choice directly extends service life in harsh environments, reducing replacement frequency and unplanned downtime.
Remote Diaphragm Seal Isolation: The 1199WDE15AFFWG2DBA9TG seal assembly physically isolates the transmitter’s sensing element from the process fluid. This prevents clogging, crystallization, or coating of the diaphragm, maintaining measurement accuracy and operational integrity in slurry, polymerization, or high-particulate applications.
HART® Protocol Digital Integration: The embedded HART® communication capability allows for remote configuration,
