     • Cost-effective solution for duct pressure/air velocity monitoring.
10. Density/Interface Detection
    • Recommended Model: Rosemount 3051HP
      • High-precision absolute pressure measurement (±0.04%). Identifies liquid density/liquid-liquid interfaces in separation processes.

Key Selection Factors

• Media Compatibility:
  • Corrosive media: Opt for tantalum/Hastelloy diaphragms (Rosemount 3051TG).
  • Viscous fluids: Use flat-diaphragm direct mounting (Rosemount 3051L).
• Environmental Requirements:
  • Explosion-proof: SIL2/3-certified models (e.g., Rosemount 3051S).
  • Submersible: IP68-rated models (e.g., Rosemount 3051TA).
• Accuracy vs. Cost:
  • Routine control: Rosemount 3051CD (cost-effective).
  • Precision tasks: Rosemount 3051HP/3051S (high accuracy).
