Engineered for harsh environments, the Rosemount 3051TG3A2B21AI1M5DOP1Q4Q8S1QTHR7+1199WDF59WFF18A4314 remote diaphragm seal delivers precise measurement with 4-20 mA with digital signal based on HART® Protocol.
The Rosemount 3051TG3A2B21AI1M5DOP1Q4Q8S1QTHR7+1199WDF59WFF18A4314 represents the pinnacle of precision pressure measurement for demanding process environments. This integrated Remote Diaphragm Seal (RDS) system combines the industry-standard 3051T Coplanar™ pressure transmitter with a purpose-engineered 1199 series seal assembly. Designed for applications involving viscous, corrosive, or high-temperature media, this configuration delivers a 4-20 mA output signal superimposed with a digital HART® Protocol signal, enabling seamless integration into existing Distributed Control Systems (DCS) and asset management platforms. The unit is engineered for absolute pressure measurement (0 to 800 psia) and gauge pressure measurement (-14.7 to 800 psi), providing the operational integrity required for critical custody transfer and safety-instrumented functions.
Key Features & High-End Benefits
Advanced Signal Integrity: The 4-20 mA HART® protocol ensures reliable, noise-immune communication over long cable runs, while the digital overlay allows for remote diagnostics, configuration, and multivariable process data retrieval. This facilitates predictive maintenance and reduces unscheduled downtime.
Superior Material Compatibility: The specified Material of Construction (Code 43) and the 1199WDF59WFF18A4314 seal assembly are selected for exceptional resistance to aggressive chemical attack and high-temperature excursions. This metallurgical choice directly extends the mean time between failures (MTBF) in harsh environments such as hydrocarbon processing, refining, and chemical production.
Optimized Measurement Range: With a full-scale capability of 800 psi and a turndown ratio exceeding 100:1, the transmitter offers unmatched flexibility. This allows a single
-14.7 to 800 psi (-1.01 to 55.15 bar) [3051TG]; 0 to 800 psia (0 to 55.15 bar) [3051TA]
