  • Probe: -20℃~+800℃ (-4℉~1472℉)
• Protection Class:
  • Transmitter: IP65 (for harsh industrial environments)
  • Probe: IP68 (when properly installed with flange seals)
• Compliance Standards: IEC 61010-1 (safety), IEC 61326-1 (EMC immunity), EN 50545 (emission monitoring)

2. Product Features

• In-Situ Zirconia Measurement: Directly measures O₂ in flue gas at the point of emission (no sample extraction required), eliminating delays from gas sampling systems and ensuring real-time data for combustion control.
• Durable Probe Design: Heat-resistant alloy probe withstands temperatures up to 800℃ (1472℉) and resists corrosion from sulfur-containing or reducing gases—extending service life in harsh applications (e.g., waste incineration, sulfur recovery).
• Proven Sensor Reliability: 50+ years of ABB’s composite electrode technology enhances sensor tolerance to harsh gases and high temperatures, reducing replacement frequency and maintenance costs.
• Integrated Automatic Calibration: The Endura AZ20 auto-calibration system controls calibration gas sequence, verifies gas validity, and eliminates errors from gas leakage—ensuring accurate measurements without expensive external tools.
• User-Friendly Transmitter: Intuitive HMI (Human-Machine Interface) simplifies configuration and operation; HART and IrDA interfaces enable remote access (via DTM—Device Type Manager) for parameter adjustment, data logging, and firmware updates.
• Flexible Output Configuration: Standard analog/digital outputs plus optional expansions adapt to diverse control systems (e.g., DCS, PLCs) in power plants, incinerators, or industrial boilers.
• Environmental Compliance: Meets global emission monitoring standards (e.g., EN 50545), supporting compliance with local air quality regulations for NOₓ, SO₂, and CO₂ reduction.

3. Application Fields

• Power Generation: Optimizes combustion in coal-fired, gas-fired, or biomass boilers—reducing fuel consumption and minimizing NOₓ emissions from power plants.
• Waste Incineration: Monitors O₂ in flue gas from industrial/medical waste incinerators and crematoria—ensuring complete combustion to reduce toxic byproducts (e.g., dioxins).
• Petrochemical & Refining: Used in sulfur recovery units (SRUs) and refinery heaters to control O₂ levels, preventing catalyst poisoning and improving process efficiency.
• Industrial Boilers: Optimizes combustion in cement, steel, and chemical plant boilers—lowering energy costs and meeting emissions targets for industrial processes.
• District Heating: Controls O₂ in municipal heating boilers to enhance fuel efficiency and reduce greenhouse gas (GHG) emissions from centralized heating systems.

4. Precautions

• Probe Installation: Ensure the probe is inserted to the correct depth (per application requirements) to avoid measurement errors from non-representative flue gas sampling; use compatible flanges for airtight sealing.
• Calibration Gas Selection: Use certified calibration gases (e.g., 21% O₂ for air calibration, 0% O₂ for zero calibration) to maintain accuracy—expired or contaminated gases will invalidate calibration.
• Temperature Limitations: Do not exceed the probe’s maximum operating temperature (800℃/1472℉); use a heat exchanger for flue gas temperatures above this range to prevent sensor damage.
• Corrosion Protection: In high-sulfur or acidic gas environments, select optional corrosion-resistant probe materials (e.g., Hastelloy) to extend service life.
• Power Supply Stability: Use a regulated 24V DC power supply with surge protection to avoid transmitter malfunctions from voltage spikes.
• Regular Maintenance: Inspect the probe for soot buildup or corrosion every 3~6 months (depending on application); clean or replace the sensor per ABB’s recommended maintenance schedule to ensure reliable measurements
