Professional-grade Rosemount 3051TG4A2B21KS1B4E5Q4Q8QTM5P1Q15+1199WDA95ARFW46DAA5Q15 remote diaphragm seal offering -14.7 to 4000 psi (-1.01 to 275.79 bar) [3051TG]; 0 to 4000 psia (0 to 275.79 bar) [3051TA] capabilities alongside robust 4-20 mA with digital signal based on HART® Protocol.
The Rosemount 3051TG4A2B21KS1B4E5Q4Q8QTM5P1Q15+1199WDA95ARFW46DAA5Q15 represents a premier solution in pressure measurement technology, specifically engineered for demanding process environments where isolation of the sensing element from the process fluid is paramount. This Remote Diaphragm Seal (RDS) assembly integrates the high-performance 3051TG transmitter with a purpose-matched 1199 diaphragm seal system, delivering superior accuracy and reliability for applications involving corrosive, viscous, or high-temperature media. The configuration supports a robust measurement range from -14.7 to 4000 psi (-1.01 to 275.79 bar) for gauge pressure variants and 0 to 4000 psia (0 to 275.79 bar) for absolute pressure, ensuring compatibility with a wide spectrum of industrial processes. With a 4-20 mA output signal enhanced by digital HART® Protocol communication, this assembly provides real-time process data alongside analog control, facilitating seamless integration into existing Distributed Control Systems (DCS) and asset management platforms. The DA material construction ensures exceptional corrosion resistance, extending service life in harsh chemical and hydrocarbon processing environments.
Key Features & High-End Benefits
The primary feature of this assembly is its remote diaphragm seal architecture, which physically isolates the 3051TG transmitter from the process fluid via a capillary-fill system. This design eliminates direct contact between the sensing element and aggressive media, preventing corrosion, clogging, and thermal damage—directly enhancing operational integrity and reducing unplanned downtime. The HART® Protocol communication enables bidirectional digital data exchange, allowing for remote configuration, diagnostics, and multivariable process variable access (e.g., pressure, temperature, and sensor status) without interrupting the analog loop. This capability drives process optimization by enabling predictive maintenance and real-time performance monitoring. The inclusion of
