Professional-grade Rosemount 3051CD3A22A1BS8M5B4K8L4P1Q4Q8+1199WDB54AFFWG4DAA9H+1199MDB54AFFWG4DAA9H remote diaphragm seal offering -1000 to +1000 inH2O (-2.48 to +2.48 bar) [3051CD/CG]; 0 to 800 psia (0 to 55.15 bar) [3051CA] capabilities alongside robust 4-20 mA with digital signal based on HART® Protocol.
The Rosemount 3051CD3A22A1BS8M5B4K8L4P1Q4Q8+1199WDB54AFFWG4DAA9H+1199MDB54AFFWG4DAA9H represents a premier solution in remote diaphragm seal technology, engineered for demanding process environments where operational integrity is non-negotiable. This integrated assembly combines the proven 3051C Coplanar™ pressure transmitter with two high-performance remote diaphragm seals (Models 1199WDB and 1199MDB), delivering precise differential pressure measurement across a calibrated range of -1000 to +1000 inH₂O (-2.48 to +2.48 bar) for the differential/gauge variant, and 0 to 800 psia (0 to 55.15 bar) for absolute pressure applications. The system outputs a 4-20 mA signal with digital HART® Protocol, enabling seamless integration into existing Distributed Control Systems (DCS) for real-time process optimization. The “DA” material construction ensures robust compatibility with aggressive media, providing long-term reliability in chemical, hydrocarbon, and high-temperature processes.
Key Features & High-End Benefits
Advanced Diaphragm Seal Isolation: The dual-seal configuration (1199WDB and 1199MDB) isolates the transmitter from corrosive, viscous, or slurry-based process fluids, eliminating direct contact with the sensing element. This extends instrument lifecycle and reduces unplanned maintenance downtime, directly enhancing operational integrity in critical service applications.
High-Accuracy Digital Communication: The HART® Protocol integration facilitates remote configuration, diagnostics, and multi-variable data retrieval without requiring field intervention. This enables predictive maintenance strategies and real-time process optimization, as operators can monitor fill fluid integrity, temperature effects, and line
