Engineered for harsh environments, the Rosemount 3051CD4A22A1KS2B4K8M5P1Q4Q8QTQ15+1199BDC59AFFWG1DAA9UQ15+1199CDC59AFFWG1DAA9UQ15 remote diaphragm seal delivers precise measurement with 4-20 mA with digital signal based on HART® Protocol.
The Rosemount 3051CD4A22A1KS2B4K8M5P1Q4Q8QTQ15+1199BDC59AFFWG1DAA9UQ15+1199CDC59AFFWG1DAA9UQ15 is a high-performance, fully integrated remote diaphragm seal system engineered for demanding process environments where direct instrument mounting is impractical or detrimental to measurement accuracy. This configuration combines the industry-standard 3051S Coplanar™ pressure transmitter with two isolated, fill-fluid-filled diaphragm seal assemblies (Model 1199), enabling precise differential pressure measurement across a range of -300 to +300 psi (-20.68 to +20.68 bar). The system is purpose-built to isolate the transmitter from corrosive, viscous, high-temperature, or slurry-laden media, ensuring operational integrity in critical B2B applications such as chemical processing, oil & gas refining, and pharmaceutical manufacturing. With a 4-20 mA output enhanced by digital HART® Protocol communication, this solution delivers real-time process data for superior control room visibility and asset management.
Key Features & High-End Benefits
Advanced Diaphragm Seal Isolation: The dual 1199 series seals (materials: DA) provide robust physical separation between the process fluid and the transmitter’s sensing element. This eliminates direct contact with aggressive chemicals, high-viscosity polymers, or abrasive slurries, significantly extending service life and reducing maintenance downtime. The result is a measurable increase in process uptime and a lower total cost of ownership.
HART® Protocol Digital Integration: The 4-20 mA analog signal is overlaid with a digital HART® communication layer, allowing for remote configuration, diagnostics, and multivariable data retrieval. This enables predictive maintenance strategies and real-time process optimization without requiring field
