The Rosemount 3051CD2F22A1AS2KDM5Q4Q8Q76, paired with the 1199WDAB4AFFW71DB00Q8Q76 and 1199MDB55AFFW71DB00Q8Q76 remote diaphragm seals, represents a premier solution for demanding process measurement applications. This integrated assembly leverages the proven performance of the 3051C Coplanar™ pressure transmitter with the isolation capabilities of high-performance remote seals. Configured with Alloy C-276 wetted materials, this system is engineered to withstand highly corrosive environments while delivering precise differential pressure measurement. The FOUNDATION™ Fieldbus protocol output ensures seamless integration into modern distributed control systems (DCS), enabling advanced diagnostics and asset management. With a calibrated range spanning -250 to +250 inH₂O for differential pressure and 0 to 150 psia for absolute pressure, this assembly is ideal for applications requiring both high sensitivity and robust overpressure protection.
Key Features & High-End Benefits
Advanced Material Compatibility: The use of Alloy C-276 (Hastelloy C-276) for all wetted parts provides exceptional resistance to pitting, stress-corrosion cracking, and oxidizing agents. This ensures operational integrity in processes involving hydrochloric acid, chlorine, or high-temperature seawater, drastically reducing unplanned maintenance cycles.
FOUNDATION™ Fieldbus Integration: The digital output signal enables real-time access to multiple process variables (PV, SV, TV, QV) and advanced diagnostic data. This facilitates predictive maintenance strategies and process optimization by allowing operators to monitor seal health, diaphragm fill fluid integrity, and line temperature without additional hardware.
Remote Seal Configuration for Process Isolation: The dual 1199 remote diaphragm seals physically isolate the sensitive
