The Rosemount 3051CD2A22A1AS2M5B4E8D4T1P2Q4CN+1199DCC64AFFW72DAA9H remote diaphragm seal ensures accurate process control with its 4-20 mA with digital signal based on HART® Protocol and proven performance architecture.
The Rosemount 3051CD2A22A1AS2M5B4E8D4T1P2Q4CN+1199DCC64AFFW72DAA9H represents a pinnacle of precision differential pressure measurement engineered for the most demanding process environments. This integrated Remote Diaphragm Seal (RDS) assembly combines the proven 3051C Coplanar platform with a fully welded, hermetically sealed diaphragm system. Designed to isolate sensitive transmitter electronics from corrosive, viscous, or high-temperature media, this configuration ensures uninterrupted operational integrity in critical applications such as hydrocarbon processing, chemical distillation, and pharmaceutical synthesis. The unit delivers a standard 4-20 mA output with digital HART® Protocol communication, enabling seamless integration into existing Distributed Control Systems (DCS) or Safety Instrumented Systems (SIS). With a robust DA material construction and a comprehensive selection of process connection and fill fluid options, this assembly is purpose-built for high-accuracy differential pressure measurement across a range of -250 to +250 inH₂O, while the absolute pressure variant extends to 0–150 psia.
Key Features & High-End Benefits
Remote Diaphragm Seal Integration (1199DCC64AFFW72DAA9H): The 1199 series seal isolates the transmitter from process media containing solids, polymers, or high vapor pressure components. This eliminates plugging, crystallization, and corrosion at the sensing element, drastically reducing unplanned maintenance and extending Mean Time Between Failures (MTBF). The fully welded construction guarantees zero fugitive emissions, supporting stringent environmental compliance mandates.
Advanced Diagnostics & HART® Protocol (Output: 4-20 mA HART): The integral HART® digital signal provides access to advanced diagnostics including loop integrity checks, electronics temperature
