Professional-grade Rosemount 2051TG3A2B21AS1E1M5D4Q4Q8QTQ15HR7+1199WDA95AFFWG1DA00Q15 remote diaphragm seal offering -14.7 to +800 psi (-1.0 to +55 bar) / 0 to 800 psia (0 to 55 bar) capabilities alongside robust 4–20 mA with digital signal based on HART® Protocol.
The Rosemount 2051TG3A2B21AS1E1M5D4Q4Q8QTQ15HR7+1199WDA95AFFWG1DA00Q15 represents the pinnacle of pressure measurement technology for demanding process environments. This integrated Remote Diaphragm Seal (RDS) system combines the proven reliability of the 2051T Coplanar™ pressure transmitter with a purpose-matched 1199 series diaphragm seal assembly. Engineered for critical applications where process media must be isolated from the sensing element, this configuration delivers exceptional accuracy and long-term stability. The unit is calibrated for a versatile measurement range spanning from -14.7 to +800 psi (-1.0 to +55 bar) for gauge applications, and 0 to 800 psia (0 to 55 bar) for absolute pressure monitoring. The 4–20 mA output, enhanced with HART® Protocol digital communication, ensures seamless integration into existing Distributed Control Systems (DCS) and Safety Instrumented Systems (SIS), providing real-time process visibility and remote diagnostic capabilities.
Key Features & High-End Benefits
This Rosemount RDS solution is defined by features that directly translate into superior operational integrity and process optimization. The HART® Protocol enables advanced digital diagnostics, allowing for predictive maintenance by alerting operators to potential issues such as diaphragm rupture, process temperature extremes, or seal degradation before they cause unplanned downtime. The high-performance 1199WDA95AFFWG1DA00Q15 diaphragm seal, constructed with material code DA, offers exceptional corrosion resistance and compatibility with aggressive or viscous media, ensuring reliable performance in harsh chemical or abrasive environments. The wide turndown capability of the 2051TG platform, combined with the seal’s optimized fill fluid, minimizes temperature-induced errors, delivering precise pressure readings across the full -14.7
