Key Advantages & Applications
Reliable Performance: Long-life zirconia sensor with field-replaceable heater assembly reduces maintenance costs and downtime.
Flexible Configuration: Multiple probe lengths, flange types, and reference gas options (natural convection/instrument air/pressure-compensated) adapt to diverse installation scenarios.
Seamless Integration: HART 7 and Modbus TCP/RTU communication enable remote monitoring, calibration, and data integration with DCS/PLC systems.
Industrial-Grade Durability: Corrosion-resistant materials and IP44D/IP66 ingress protection (with sealed cable gland) withstand harsh industrial environments.
Typical applications include power plant boilers (coal/gas/oil-fired), steel mill reheating furnaces, petrochemical cracking furnaces, cement kilns, and waste-to-energy incinerators. It supports combustion efficiency optimization by maintaining optimal O₂ levels, reducing fuel consumption and greenhouse gas emissions while ensuring compliance with environmental regulationsYokogawa Electric Corporation.
Installation & Maintenance Notes
Mounting: Flange-mounted (JIS 5K 65FF); probe insertion angle: horizontal to vertically downward (≤±5° for lengths ≤2m; vertical for >2.5m).
Calibration: Zero/span calibration (0.3–100 vol% O₂ zero range; 4.5–100 vol% O₂ span range) via manual/semi-automatic mode (ZR20H calibration unit optional).
Accessories: ZR22R probe protector (for particulate-laden flue gases), ZR22V support clamp (for long probes), and fly ash filters (for high-dust environments).
The Yokogawa ZR22G100SKCTTEA delivers industry-leading performance for industrial combustion oxygen monitoring, combining precision, durability, and versatility to meet the demands of modern process industries.
