The Rosemount 3051CD2F22A1AS2B4K5Q4Q8+1199DCC59AFFW71DB00+1199DCC59AFFW71DB00 is a highly reliable remote diaphragm seal featuring FOUNDATION™ Fieldbus Protocol, designed for demanding industrial applications.
The Rosemount 3051CD2F22A1AS2B4K5Q4Q8+1199DCC59AFFW71DB00+1199DCC59AFFW71DB00 represents the apex of differential pressure measurement for the most corrosive and demanding process environments. This fully configured Remote Diaphragm Seal system integrates a Coplanar™ pressure transmitter with two Alloy C-276 remote seals, engineered to isolate the sensing element from aggressive media. Utilizing a FOUNDATION™ Fieldbus output, this assembly delivers high-resolution digital process data directly to your control network, enabling advanced diagnostics and seamless asset management. The system is specifically designed for applications where process fluid compatibility, high-temperature isolation, and long-term operational stability are non-negotiable.
Key Features & High-End Benefits
Alloy C-276 Material Construction: The wetted diaphragm and seal body are fabricated from Hastelloy® C-276, offering exceptional resistance to pitting, stress-corrosion cracking, and oxidizing agents. This metallurgical choice ensures operational integrity in environments containing chlorides, sulfuric acid, or wet chlorine, drastically reducing lifecycle costs associated with material degradation. FOUNDATION™ Fieldbus Protocol Integration: The 3051CD transmitter with FOUNDATION Fieldbus output provides full digital communication, including cyclic data, alarm management, and multi-variable measurement capabilities. This enables process optimization through real-time compensation for static pressure and temperature effects, while reducing wiring complexity and installation costs. Extended Measurement Range & Stability: Capable of measuring differential pressures from -250 to +250 inH2O, with an absolute pressure range of 0 to 150 psia, this system delivers high accuracy across a broad spectrum of flow, level, and pressure applications. The remote seal configuration dampens
