Model: EL3020 (Gas Analyzer)

Product Type: Continuous Gas Analyzer Benchtop/Wall-Mounted Housing (Compact Design)

ABB EL3020 GAS ANALYZER

Technical Parameters:

Measurement Principles: Integrates up to two analyzer modules to measure up to four gas components simultaneously. Utilizes Non-Dispersive Infrared (NDIR) photometers (Uras26), Paramagnetic or Electrochemical Oxygen sensors (Magnos206), or Thermal Conductivity detectors (Caldos27).

Monitored Gases: Quantifies concentration levels for infrared-active gases such as CO, CO2, SO2, CH4, and NO, alongside O2, H2, and He tracking.

Enclosure Variation: Housed in a compact, space-saving benchtop or wall-mounted enclosure (protection class IP65 option for specific configurations), differing from the larger 19-inch rack-mount EL3040 model.

Linearity and Drift Error: Zero-point drift is minimized to $\le$ 1% of the span per week; linearity deviation remains within $\le$ 1% of the full-scale value.

Internal Calibration Unit: Built-in calibration cell technology option for NDIR components, enabling automated zero and span checks without relying on standard calibration gas cylinders.

Analog Output Matrix: Features up to 4x isolated 0/4-20 mA current outputs configured to transmit gas concentration values directly to remote recording systems.

Digital Communication Network: Equipped with an onboard Modbus TCP/IP Ethernet interface alongside options for serial RS-485 Modbus or Profibus DP data structures.

Display Configuration: Built-in backlit, multi-line digital LCD display on the front panel providing real-time data metrics, clear text status error strings, and manual configuration access.

Power Supply Input: Flexible global internal power input accommodating 100-240 VAC, 50/60 Hz single-phase lines.

Industrial Sectors:

Chemical Manufacturing, Industrial Gas Production, Air Separation Plants, Food and Beverage Processing (Modified Atmosphere Packaging), Biogas and Bio-methane Utilities, Landfill Gas Recovery, and Environmental Safety Monitoring.

Application Scenarios:

1. Purity Verification in Air Separation Plants: Installed in industrial gas generation facilities to monitor trace impurities (such as CO or CO2) in high-purity Nitrogen, Oxygen, or Argon process pipelines.

2. Biogas Methane Yield Optimization: Deployed in agricultural or municipal anaerobic digestion plants to continuously trace CH4 (methane) and O2 levels, safeguarding the extraction process from explosive atmosphere mixtures.

3. Controlled Atmosphere Storage Monitoring: Positioned inside commercial cold-storage facilities and fruit warehouses to track precise CO2 and O2 concentrations, ensuring optimal preservation conditions for stored agricultural products.

4. Localized Scrubber Efficiency Checks: Integrated into small-scale chemical venting stacks or laboratory scrubbers to audit the reduction of gas pollutants (like SO2 or CO) before air is exhausted to the exterior environment.
