The Rosemount 3051CD2A22A1JS2E8P1Q4Q8+1199TDK60AFFW74DAA9GE+1199SDK60AFFW74DAA9G 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 3051CD2A22A1JS2E8P1Q4Q8+1199TDK60AFFW74DAA9GE+1199SDK60AFFW74DAA9G represents a fully integrated Remote Diaphragm Seal (RDS) solution engineered for high-accuracy differential pressure measurement in demanding process environments. This assembly combines the industry-standard 3051C Coplanar™ pressure transmitter with two complete remote seal assemblies, providing a sealed, fill-fluid system that isolates the transmitter from corrosive, viscous, or high-temperature process media. The configuration delivers a 4-20 mA output with digital HART® Protocol communication, enabling seamless integration into existing Distributed Control Systems (DCS) for real-time monitoring and process optimization. With a measurement range of -250 to +250 inH₂O (-621.60 to +621.60 mbar) for the differential pressure (CD) variant, this system is optimized for low-differential applications such as level, density, and interface measurement in sealed or open vessels.
Key Features & High-End Benefits
This remote diaphragm seal system is characterized by its material code DA, which specifies Hastelloy C-276 for both the diaphragm and wetted parts, ensuring exceptional resistance to pitting, stress corrosion cracking, and oxidizing agents. The 1199 series seals feature a fully welded construction, eliminating potential leak paths and enhancing operational integrity under extreme thermal cycling or vacuum conditions. The advanced fill-fluid system, combined with the 3051C’s patented Coplanar™ design, provides superior temperature compensation and minimizes thermal transient errors, delivering a total performance accuracy better than 0.075% of span. For process optimization, the HART® digital signal allows for remote diagnostics, multi-variable data retrieval, and predictive maintenance capabilities, reducing unplanned downtime.
