ABB EL3020 Continuous Gas Analyzer  

1. Key Parameters

• Product Model: EL3020
• Product Series: ABB Industrial Continuous Gas Analyzers (Real-Time Gas Composition Monitoring)
• Core Function: Continuous gas concentration analysis; real-time data transmission; over-limit alarm; self-diagnosis; industrial system compatibility.

2. Core Features

• High Stability: Equipped with anti-interference sensors and temperature-compensated circuits, ensuring consistent accuracy even in fluctuating industrial environments.
• Continuous Uninterrupted Monitoring: 24/7 real-time analysis with no sampling gaps, avoiding missed over-limit events.
• Easy Maintenance: Built-in automatic calibration function (manual / 定时) and self-diagnosis (sensor fault, sampling blockage), reducing manual maintenance workload.
• System Compatibility: Supports 4-20mA and industrial communication protocols, seamlessly connecting to ABB DCS (e.g., Symphony Plus) or third-party control systems.

3. Application Fields

• Environmental Protection: Monitors flue gas concentrations (SO₂, NOₓ, O₂) in power plants, waste incineration plants, and steel mills to meet emission standards.
• Chemical Industry: Analyzes process gas components (e.g., CO in reactor tail gas, O₂ in inert protection gas) to ensure reaction safety and product quality.
• Energy Sector: Measures O₂ concentration in boiler flue gas of thermal power plants, optimizing combustion efficiency and reducing energy consumption.
• Metallurgy: Monitors CO/CO₂ in blast furnace gas, guiding fuel adjustment and improving smelting efficiency.

4. Precautions

• Installation Environment: Avoid installing in dusty, corrosive gas, or high-humidity areas; ensure good ventilation to prevent sensor damage.
• Regular Calibration: Perform zero/span calibration every 3-6 months (per usage scenario) to maintain measurement accuracy; use ABB-certified calibration gas.
• Sampling System Maintenance: Clean the sampling filter and pipeline monthly to prevent blockage, which may cause delayed response or inaccurate data.
• Spare Parts: Use genuine ABB sensors and accessories; non-genuine parts may lead to measurement deviations or analyzer malfunctions.
