The Rosemount 3051S2CD2A2B12A1KB4M5Q4Q8I1QTD1P1+1199DDC55GFFW72DA00 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 3051S2CD2A2B12A1KB4M5Q4Q8I1QTD1P1+1199DDC55GFFW72DA00 represents the pinnacle of precision differential pressure measurement in high-temperature, corrosive, or viscous process environments. This integrated Remote Diaphragm Seal (RDS) system combines the industry-proven 3051S SuperModule platform with a purpose-engineered 1199 seal assembly. Designed for critical applications in chemical, hydrocarbon, and power generation sectors, it delivers a 4-20 mA output overlaid with HART® digital protocol, ensuring seamless integration into existing Distributed Control Systems (DCS) and asset management networks. The configuration supports a differential/gauge range of -250 to 250 inH2O and an absolute pressure range up to 150 psia, providing exceptional sensitivity for low-pressure processes while maintaining robust overpressure protection.
Key Features & High-End Benefits
This unit is specified with a DA material construction (Hastelloy C-276 for wetted parts), offering superior resistance to pitting and stress-corrosion cracking in chloride-laden or acidic media. The remote seal eliminates direct contact between the transmitter element and the process fluid, significantly reducing the risk of impulse line plugging, freezing, or coating. This translates directly to reduced unscheduled downtime and lower total cost of ownership through minimized maintenance interventions. The HART® protocol enables remote diagnostics, including seal health monitoring and loop integrity checks, facilitating predictive maintenance strategies. The integrated capillary system with temperature compensation ensures measurement stability even with ambient temperature swings, a critical factor for custody transfer or reactor pressure control where operational integrity is non-negotiable.
