Engineered for harsh environments, the Rosemount 3051CD2A22A1AS2M5B4E8D4T1P2Q4CN+1199DLC64AEFW91DA60ED0730 remote diaphragm seal delivers precise measurement with 4-20 mA with digital signal based on HART® Protocol.
The Rosemount 3051CD2A22A1AS2M5B4E8D4T1P2Q4CN+1199DLC64AEFW91DA60ED0730 represents a pinnacle of precision pressure measurement, engineered as a fully integrated Remote Diaphragm Seal (RDS) system. This configurable assembly combines the industry-proven 3051C Coplanar™ transmitter with a purpose-matched 1199 series diaphragm seal, designed to deliver reliable differential pressure (DP) and absolute pressure (AP) readings in harsh, corrosive, or high-temperature process environments. The system supports a robust 4-20 mA output with HART® Protocol, enabling seamless integration into existing Distributed Control Systems (DCS) and Asset Management platforms. With a material code designation of ‘DA’—indicating Hastelloy C-276 for both the diaphragm and wetted parts—this configuration is specifically engineered to withstand aggressive chemical attack and process fouling, ensuring long-term operational integrity in critical applications such as hydrocarbon processing, chemical reactor monitoring, and steam flow measurement.
Key Features & High-End Benefits
HART® Protocol Integration for Advanced Diagnostics: The 4-20 mA loop with HART® digital overlay provides not only a standard analog signal but also access to real-time device diagnostics, multivariable process data, and configuration parameters. This enables predictive maintenance strategies, reducing unplanned downtime by allowing operators to remotely verify seal health, process temperature, and static line pressure without field intervention.
Hastelloy C-276 (Material DA) for Extreme Corrosion Resistance: The ‘DA’ wetted material specification ensures superior resistance to pitting, stress-corrosion cracking, and oxidizing environments. This translates to extended service life in chlorinated hydrocarbons, sour gas (H₂S), and
