Engineered for harsh environments, the Rosemount 3051TG3A2B21BWR3S1E8Q4Q8QTD4M5DOC1P1Q15HR7+1199WDA93AFFW71DAA9NGQ15WR3 remote diaphragm seal delivers precise measurement with 4-20 mA with digital signal based on HART® Protocol.
The Rosemount 3051TG3A2B21BWR3S1E8Q4Q8QTD4M5DOC1P1Q15HR7 integrated with the 1199WDA93AFFW71DAA9NGQ15WR3 remote diaphragm seal system represents the pinnacle of precision pressure measurement for demanding process environments. This assembly combines the proven performance of the 3051T in-line pressure transmitter with a fully welded, direct-mount remote seal engineered for applications requiring isolation from corrosive, viscous, or high-temperature media. The unit delivers a 4-20 mA output with digital HART® Protocol communication, enabling seamless integration into existing distributed control systems (DCS) and asset management platforms. With a measurement range spanning from -14.7 to 800 psi (-1.01 to 55.15 bar) for gauge configurations and 0 to 800 psia (0 to 55.15 bar) for absolute versions, this solution is optimized for critical custody transfer, filtration monitoring, and reactor pressure oversight.
Key Features & High-End Benefits
Advanced Diaphragm Seal Technology: The 1199WDA93AFFW71DAA9NGQ15WR3 remote seal features a robust design with material code DA, providing exceptional resistance to process media attack and thermal cycling. This ensures sustained operational integrity in harsh chemical, refining, and hydrocarbon processing applications. The seal’s capillary fill system minimizes temperature-induced errors, delivering drift-free performance over extended operational periods.
Digital Process Optimization via HART® Protocol: The integrated HART® communication layer allows for real-time diagnostics, remote configuration, and multivariable data access. Engineers can monitor diaphragm seal integrity, detect fill fluid loss, and perform predictive maintenance without interrupting process flow. This capability directly reduces unplanned downtime
