ABB’s official documentation identifies the EL3020 as the 19-inch rack-mounted version of the EasyLine EL3000 family. Its enclosure is approximately 483 mm wide × 357 mm deep × 132 mm high, while the wall-mounted EL3040 uses a different enclosure.
The analyzer can accommodate up to two measurement modules, allowing combinations such as an infrared photometer with an oxygen analyzer. ABB lists Uras26 infrared, Limas23 UV, Magnos oxygen, Caldos thermal-conductivity, ZO23 trace-oxygen, and Fidas24 FID technologies within the broader EL3000 family.
For process-gas handling, ABB specifies a typical sample-gas flow of 30–90 l/h. Condensation must be controlled; the sample-gas dew point should remain at least 5°C below the temperature throughout the sample path.
Application Scenarios & Pain Points
Gas analyzers often fail operationally because of the sample-conditioning system rather than the analyzer electronics. Condensation, blocked filters, unstable flow, and contaminated sample lines can make a healthy measurement module look defective.
- Continuous emissions monitoring: EL3020 can be configured with suitable analyzer modules for continuous measurement of combustion and process gases.
- Combustion/process control: Depending on the installed analyzer modules, measurements can include CO, CO₂, NO, SO₂, O₂, CH₄ and other process-gas components.
- Chemical and petrochemical plants: Multi-component analysis can be configured by combining different analyzer modules in the same housing.
- DCS/SCADA integration: Ethernet, Modbus, Profibus, analog, and digital interface options allow measured values and status information to be transferred to plant control and monitoring systems.
Field note: Before condemning an EL3020, inspect the sample line first. A wet filter or unstable sample flow can create drifting readings that look like calibration failure. The gas path deserves the same attention as the electronics.

The Engineer’s Guide: Field Pitfalls to Avoid
⚠️ EL3020 does not define the measured gas by itself.
The EL3020 is the housing/platform. The installed analyzer modules determine what is actually measured.
How to avoid it: Record the complete analyzer configuration, including module type, measurement range, gas path, and options. Ordering an housing without matching the analyzer modules can leave you with the correct cabinet size but the wrong measurement function.
⚠️ Sample conditioning can mimic analyzer failure.
ABB specifies controlled sample-gas flow and dew-point conditions. Excess moisture can cause measurement errors and condensation inside the sample path.
How to avoid it: Check filters, condensate traps, sample-gas cooler, flow rate, pressure, tubing, and sample temperature before replacing electronics.
⚠️ Do not confuse with EL3040.
is the 19-inch rack version, while EL3040 is a wall-mounted enclosure with different dimensions and environmental protection.
How to avoid it: Match the complete model designation and physical installation requirements. A functional analyzer in the wrong enclosure format is still the wrong spare.
Frequently Asked Questions (FAQ)
What is ABB ?
is a 19-inch rack-mounted continuous gas analyzer from the family. It can accommodate up to two analyzer modules in one housing.
What gases can ABB measure?
There is no single fixed gas list for every . The measurement capability depends on the installed analyzer modules. ABB’s platform supports technologies covering gases such as CO, CO₂, CH₄, SO₂, NO, O₂, and hydrocarbons, among others.
Is an oxygen analyzer?
It can be configured for oxygen measurement, but itself is the analyzer platform/housing. For example, ABB lists Magnos206 and other oxygen technologies as compatible analyzer modules.
What is the difference between and EL3040?
The primary difference is the enclosure and installation method. is a 19-inch rack-mounted analyzer, while EL3040 is a wall-mounted unit. ABB specifies approximately 483 × 357 × 132 mm for and 360 × 230 × 404 mm for .
Can communicate with a DCS?
Yes. The platform provides an Ethernet 10/100BASE-T interface and optional communication modules, including Modbus and Profibus interfaces. Analog and digital I/O modules are also available depending on the configuration.
What should I verify before buying a replacement ?
Check the following rather than purchasing from the model number alone:
- Exact housing configuration.
- Installed analyzer module types.
- Measurement gases and ranges.
- Sample-gas inlet/outlet arrangement.
- Communication interface.
- Analog and digital I/O configuration.
- Power-supply requirements.
- Software/configuration version.
- Calibration history.
