High-Performance Gas Analysis for Process and Emission Monitoring
The ABB EL3020 continuous gas analyzer provides precise, real-time measurement of multiple gas components in industrial processes and emission monitoring applications. This EasyLine series analyzer integrates up to five different measurement technologies in a single 19-inch rack-mountable unit . Process engineers rely on this analyzer for accurate monitoring in power generation, chemical processing, and environmental compliance applications.
Detector Technologies and Measurement Capabilities
The ABB EL3020 supports multiple detector technologies to measure various gas components simultaneously. The Uras26 infrared photometer measures infrared-active gases such as CO, CO₂, NO, and SO₂ with high selectivity . The Limas23 ultraviolet photometer detects NO, NO₂, and SO₂, while the Magnos206 analyzer measures O₂ concentration in process gas streams . Users can configure up to five measurement components per analyzer, tailoring the unit to specific application requirements .

For specialized applications, the analyzer supports ultra-low range configurations, such as CO at 0-10 ppm for air separation units . Users can switch between multiple measurement ranges automatically via digital inputs or manually through the operator interface .
Analyzer Options and Configuration
The ABB EL3020 includes an optional integral gas feed module with a pump, solenoid valve, and flow sensor for automated sample extraction . An optional QAL3 monitoring function enables automatic drift and precision verification according to EN 14181 standards . The analyzer supports automatic calibration using built-in calibration cells, eliminating the need for test gas cylinders in many applications . Additionally, stainless steel gas paths are available for measuring flammable gases in non-hazardous environments .
Communication and Integration
This gas analyzer provides multiple communication interfaces for seamless system integration. An integrated Ethernet port supports configuration, software updates, and QAL3 data transfer . Users can connect the analyzer to DCS or SCADA systems via analog outputs (0/2/4-20 mA), Modbus, or Profibus . Furthermore, the analyzer includes a self-monitoring function that indicates when maintenance is required, reducing unplanned downtime .
Display and Operation
The ABB EL3020 features a backlit graphical display with 240 x 160 pixel resolution . Five keys provide menu-driven navigation for configuration and operation . The display shows numerical values with physical units, bar graph indicators, and up to five measured values simultaneously . Status messages and symbols provide clear diagnostic feedback directly on the display.
