The Rosemount 3051CD2A22A1BS2B4E8Y2M5Q4Q8QTD4T1CNHR7Z1+1199WLC56AFFW72DA00+1199MLC56AFFW72DA00 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 3051CD2A22A1BS2B4E8Y2M5Q4Q8QTD4T1CNHR7Z1+1199WLC56AFFW72DA00+1199MLC56AFFW72DA00 represents a fully integrated, high-performance remote diaphragm seal (RDS) solution designed for demanding process environments. This configuration combines the industry-standard 3051S Coplanar™ pressure transmitter with two dedicated 1199 series remote seals, providing a hermetically isolated measurement system. Engineered for differential pressure (DP) and absolute pressure (AP) applications, this assembly delivers a 4-20 mA output signal with superimposed HART® digital protocol, enabling precise, real-time process data acquisition. The system is specifically configured to handle measurement ranges from -250 to +250 inH₂O for differential/capillary applications and 0 to 150 psia for absolute pressure scenarios, ensuring versatility across a wide spectrum of industrial processes.
Key Features & High-End Benefits
Total System Isolation with Dual Seal Redundancy: The integration of two 1199 series remote seals (models WLC56AFFW72DA00 and MLC56AFFW72DA00) provides complete physical separation between the process media and the sensitive transmitter electronics. This eliminates the risk of clogging, corrosion, or crystallization within the sensing element, ensuring long-term operational integrity in viscous, abrasive, or slurry-based applications.
Advanced Diagnostics & Digital Communication: The HART® protocol-enabled 4-20 mA output allows for simultaneous analog control and digital data access. This facilitates advanced diagnostics including loop integrity checks, process variable trend analysis, and remote configuration—reducing manual intervention and enabling predictive maintenance strategies for optimized asset management.
