3. Advantages and Features

• Non-Contact Design: Eliminates electrode fouling and polarization errors in dirty or corrosive media.
• PFA Material: Superior chemical resistance for aggressive environments (vs. standard PEEK).
• Wide Bore Design: Reduces fouling risk and ensures long-term stability in slurry or high-solid processes.
• Wide Rangeability: Covers 6 decades of conductivity (1 µS/cm to 2 S/cm) for versatile applications.
• Flexible Installation: Supports bulkhead, flange, or retractable (hot-tap) mounting (e.g., PR10 holder for maintenance without process shutdown).
• Integrated Temperature Compensation: PT1000 sensor ensures accurate readings across -20°C to 130°C.

4. Application Areas and Cases

• Industry Applications: Chemical processing, oil and gas, food and beverage, pharmaceuticals, water treatment.
• Use Cases:
  • Brine Concentration Control: Monitors NaCl concentration in a food processing plant, achieving ±0.1% accuracy and reducing manual sampling by 80% (2024 case study).
  • CIP System Optimization: Measures cleaning solution strength in a pharmaceutical facility, cutting chemical waste by 30% through real-time conductivity feedback.

5. Competitor Comparison

• No Fouling/Polarization: Non-contact design avoids electrode maintenance (vs. frequent cleaning in contact sensors).
• Wider Chemical Resistance: PFA material handles hydrofluoric acid (vs. PEEK sensors limited to non-fluoride acids).
• Longer Lifespan: 10+ years in corrosive environments (vs. 3–5 years for contact sensors in similar conditions).

6. Selection Recommendations

• Material Choice: Use TF (PFA) for fluorinated acids; choose GG (PEEK) for non-aggressive media (e.g., brine).
• Temperature Range: Verify process temperature (e.g., 130°C max for PFA vs. 180°C for PEEK).
• Installation Type: Select holders (e.g., FF/FS/FH) based on pipe size (DN25–DN150) and maintenance needs (retractable PR10 for critical processes).
• Cable Length: Opt for 05 (5m) for standard setups; customize lengths (01–10m) for remote installations.

7. Precautions

• Installation: Ensure proper flow velocity (0.3–3 m/s) to prevent fouling; torque stainless steel fittings to 25–30 N·m.
• Calibration: Use Yokogawa-certified standards (e.g., 1413 µS/cm solution) every 12–24 months.
• Chemical Compatibility: Avoid use in pure water (ultra-low conductivity <1 µS/cm).
• Safety: Disconnect power before servicing; follow IEC 61508 for SIL-rated applications.
