Emerson Rosemount 3051CD Pressure Transmitter Alloy C-276 4-20mA

The Emerson Rosemount 3051CD is a high-performance intelligent differential pressure transmitter, celebrated for its precision, adaptability, and durability—especially in harsh industrial environments. As part of the renowned 3051 series, it features a flexible CoPlanar™ platform that supports differential, gauge, and absolute pressure measurements, with the Alloy C-276 variant offering exceptional corrosion resistance for aggressive media.

Its design ensures accuracy and stability across varying operating conditions, while compatibility with PlantWeb factory management networks and fieldbus technologies allows seamless integration into modern control systems. Whether for flow, level, or pressure monitoring, the 3051CD delivers reliable performance, making it a top choice for critical industrial processes.

• Superior Accuracy: Boasts a reference accuracy of ±0.075% and overall performance of ±0.15%, ensuring precise measurements even in dynamic environments.
• Broad Measurement Ranges: Differential pressure: 0.5 inH₂O to 2000 psi. Gauge pressure: 2.5 inH₂O to 2000 psi. Absolute pressure: 0.167 psia to 4000 psia, covering diverse industrial needs from low to high pressure.
• Alloy C-276 Construction: Equipped with Alloy C-276 process isolating diaphragms (a nickel-chromium-molybdenum alloy), providing exceptional resistance to corrosion, pitting, and crevice corrosion—ideal for aggressive media like acids, chlorides, and industrial chemicals.
• CoPlanar™ Platform: A flexible design that simplifies installation, supports upgrades, and integrates seamlessly with accessories (e.g., manifolds, seals), adapting to evolving application requirements.
• Advanced Sensing Mechanism: Pressure is transferred via isolation diaphragms and filling fluid to a central sensing diaphragm. Displacement of the sensing diaphragm (max 0.1 mm) is proportional to pressure and detected by capacitance plates. Capacitance differences are converted to 4-20 mA analog output or HART digital signals for real-time monitoring.
• HART Communication: Enables on-site and remote communication via tools like the Rosemount 475 operator, facilitating configuration, calibration, and diagnostics without interrupting processes.
• Robust and Compact: Lightweight, sturdy build with easy installation, suitable for space-constrained environments.
