Engineered for harsh environments, the Rosemount 3051CD2A22A1KS2M5B4K8Q4Q8QTQ15+1199BDC56AFFWG4DA00Q15U+1199CDC56AFFWG4DA00Q15U remote diaphragm seal delivers precise measurement with 4-20 mA with digital signal based on HART® Protocol.
The Rosemount 3051CD2A22A1KS2M5B4K8Q4Q8QTQ15+1199BDC56AFFWG4DA00Q15U+1199CDC56AFFWG4DA00Q15U is a fully integrated Remote Diaphragm Seal (RDS) system engineered for high-precision differential pressure measurement in demanding process environments. This configuration combines the industry-leading 3051S Coplanar™ pressure transmitter with a matched pair of 1199 series diaphragm seals, providing a hermetically sealed, leak-free solution for critical applications involving corrosive, viscous, or high-temperature media. The system delivers a 4-20 mA output signal with superimposed HART® digital protocol, enabling seamless integration into existing Distributed Control Systems (DCS) and Asset Management platforms. With a measurement range spanning -250 to +250 inH₂O for differential pressure and 0 to 150 psia for absolute pressure, this assembly ensures reliable, repeatable performance for custody transfer, level, and interface measurement applications.
Key Features & High-End Benefits
The Rosemount 3051CD2A22A1KS2M5B4K8Q8QTQ15+1199BDC56AFFWG4DA00Q15U+1199CDC56AFFWG4DA00Q15U system is engineered to maximize operational integrity and process optimization. The 3051CD transmitter core features ultra-high accuracy of ±0.04% of span, reducing measurement uncertainty and enabling tighter control of critical process variables. The integrated 1199 diaphragm seals utilize a fully welded construction with DA (Ductile Alloy) material, providing exceptional resistance to corrosion and mechanical fatigue in aggressive chemical and hydrocarbon services. The dual-seal configuration (1199BDC56AFFWG4DA00Q15U and 119
