Functional Features

  • High-Precision Sensing:
    • Utilizes a long-life zirconia sensor with three reference gas compensation methods (natural air convection, instrument air, pressure compensation) for stable performance.
  • Dual Functionality:
    • Configurable as an oxygen analyzer or high-temperature humidity analyzer (/HS option).
  • User-Friendly Interface:
    • LCD touchscreen supports trend displays, alarm settings, and self-diagnostics.
  • Flexible Installation:
    • Separate or integrated probe-converter designs reduce wiring and installation costs.
    • Optical switches enable easy field operation.
  • Remote Maintenance:
    • HART communication allows for calibration and troubleshooting without physical access.
  • Robust Design:
    • Field-replaceable heater unit in the probe minimizes downtime.
    • Anti-interference capabilities ensure reliable operation in harsh industrial environments.

Application Scenarios

  • Energy Efficiency:
    • Monitors combustion efficiency in boilers, furnaces, and incinerators to optimize fuel usage and reduce CO₂/SOx/NOx emissions.
  • Process Control:
    • Regulates oxygen levels in steel, cement, and petrochemical plants for consistent product quality.
  • Environmental Compliance:
    • Ensures adherence to emission standards in waste-to-energy plants and power generation facilities.
  • Humidity Management:
    • Measures moisture in drying processes (e.g., paper, textiles) and humidification systems (e.g., greenhouses, pharmaceuticals).
  • Safety Monitoring:
    • Detects oxygen deficiency in confined spaces (e.g., tunnels, storage tanks) to prevent hazards.

Key Advantages

  • Cost-Effective Operation:
    • Reduces maintenance costs via field-replaceable components and remote diagnostics.
  • High Reliability:
    • NEMA4X/IP66-rated converter and dustproof probe withstand extreme conditions.
  • Seamless Integration:
    • Supports 4–20 mA and HART for compatibility with existing control systems.
  • Global Certifications:
    • Complies with CENELEC, CSA, and FM standards for safety and performance.
