The Rosemount 3051CD3A22A1AS2B4M5Q4C1P1+1199DDE59AEFW92DC401+1199DDE59AEFW92DC401 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 3051CD3A22A1AS2B4M5Q4C1P1, integrated with dual 1199DDE59AEFW92DC401 remote diaphragm seals, represents a premier solution for demanding pressure measurement applications where process isolation is critical. This assembly is engineered to deliver exceptional accuracy and stability across a wide measurement range of -1000 to +1000 inH₂O (-2.48 to +2.48 bar) for differential pressure (3051CD/CG) and 0 to 800 psia (0 to 55.15 bar) for absolute pressure (3051CA). The 4-20 mA output with HART® Protocol digital signal ensures seamless integration into existing distributed control systems (DCS) and asset management platforms, providing both analog trend data and digital diagnostic capabilities. The DC material construction offers robust corrosion resistance, making this configuration ideal for harsh chemical, hydrocarbon, or high-temperature media where direct transmitter contact would compromise operational integrity.
Key Features & High-End Benefits
Remote Diaphragm Seal Integration: The dual 1199DDE59AEFW92DC401 seals physically isolate the transmitter from the process fluid, eliminating the risk of clogging, crystallization, or corrosion while maintaining high-fidelity pressure transmission. This feature directly enhances process safety and reduces unplanned maintenance interventions.
HART® Protocol Digital Communication: Beyond the standard 4-20 mA analog signal, the HART® digital overlay enables remote configuration, real-time diagnostics, and multivariable access (pressure, temperature, sensor health). This capability supports predictive maintenance strategies and reduces field service visits, directly lowering total cost of ownership.
Extended Measurement Versatility: With a dual-range capability spanning low differential pressures to high static line pressures
