The Rosemount 2051CD2A22A1BHR7S2B4I1M5DOV5P1C4+1199DDB59AFFW72DA00+1199DDB59AFFW72DA00 is a highly reliable remote diaphragm seal featuring 4–20 mA with digital signal based on HART® Protocol, designed for demanding industrial applications.
The Rosemount 2051CD2A22A1BHR7S2B4I1M5DOV5P1C4, integrated with dual Model 1199DDB59AFFW72DA00 remote diaphragm seals, represents a premier solution for demanding differential pressure and gage pressure applications. This assembly leverages the proven Coplanar™ platform to deliver a 4–20 mA output with superimposed HART® digital protocol, ensuring seamless integration into existing Distributed Control Systems (DCS) and asset management architectures. Configured for a measurement range of -250 to 250 inH₂O (-623 to 623 mbar) for both differential and gage modes, this system is engineered to maintain operational integrity in processes where process isolation, high-temperature media, or corrosive environments necessitate remote mounting. The DA material construction provides robust chemical compatibility, making this assembly suitable for critical hydrocarbon, chemical, and refining applications.
Key Features & High-End Benefits
Advanced Diaphragm Seal Technology: The dual 1199 remote seals utilize a fully welded, hermetically sealed system that isolates the transmitter from the process fluid. This eliminates the risk of clogging, freezing, or corrosion within the sensor module, thereby extending mean time between failures (MTBF) and reducing unplanned maintenance costs.
HART® Protocol Integration for Process Optimization: The 4–20 mA loop with HART® enables real-time multivariable diagnostics. End-users can access primary variable (PV) data alongside secondary variables such as sensor temperature and loop integrity checks. This facilitates predictive maintenance strategies and enhances overall equipment effectiveness (OEE) by allowing remote troubleshooting and configuration without process interruption.
Superior Rangeability and Accuracy: With a turndown ratio exceeding 100:1, this configuration provides exceptional
Differential: -250 to 250 inH₂O (-623 to 623 mbar); Gage: -250 to 250 inH₂O (-623 to 623 mbarr)
