ABB EL3020 EL3040 Continuous Gas Analyzers

Specification

Measurement techniques and ranges: 

The analysers include a variety of measurement techniques, 

Uras26 infrared photometer is based on the principle of non-dispersive infrared absorption, and can measure CO, 

NO and other gases, with measurement ranges such as CO from 0 - 100 ppm to 0 - 100 vol.%, etc.; 

Limas23 ultraviolet photometer adopts different methods to measure NO, NO 2, and SO 2, and the measurement ranges are also different.

Stability index: each analyser has different performance in stability, 

Uras26 linearity deviation ≤1% of span, repeatability ≤0.5% of span, zero drift ≤1% of span per week, etc.; 

Limas23 linearity deviation ≤1% of span, repeatability ≤0.5% of span, zero drift ≤2% of span per week for NO week, etc.

Response time and calibration: Warm-up time and 90% response time are different, 

Uras26 warm-up time without thermostat is about 30 minutes, 90% response time T90 ≤ 2.5 seconds;

 calibration methods are automatic, manual and external control, 

automatic calibration is commonly used in built-in calibration cell or single-point calibration.

Electrical interfaces and gas connection: Equipped with Ethernet, Modbus, 

Profibus and other electrical interfaces, as well as a variety of I/O modules; gas connection methods, different models of analysers with different gas inlet, 

outlet and connection interface.

Other specifications: 19-inch rack-mountable (EL3020) and wall-mountable (EL3040) housings, with protection ratings of IP20 and IP65;

 power supply requirements of AC 100 - 240V and DC 24V, etc., with different power consumption for different analysers.

Technical features

Multi-measurement technology integration: Adopting a variety of advanced measurement technologies to accurately detect different gas characteristics 

and meet the needs of complex gas composition monitoring.

Powerful Measurement Functions: One instrument can measure up to five sample compositions, with a wide range of flexible adjustments, 

and can also be combined with different analysers to meet special measurement requirements.

Convenient operation and maintenance: automatic calibration function, which can be initiated based on time, external signals or Modbus, 

simplifies the calibration process; self-monitoring function prompts maintenance needs in time.

Flexible configuration and communication: A variety of electrical interfaces are provided to facilitate communication 

and data transmission with external systems; parameters can be set through 

the configuration software to achieve analogue output and digital input/output functions.

Reliable safety performance: high protection level of the shell, adapt to different installation environments;

 through a variety of safety certifications, in line with European and other regional standards, some models have explosion-proof design.

Additional models

EL3020-HC (Highly Corrosive Gas Specific): On the basis of the original, for highly corrosive gas environment, 

using more corrosion-resistant materials, optimising the gas circuit design, 

enhancing the resistance to corrosive gases, suitable for chemical, metallurgical and other industries containing highly corrosive gas monitoring scenarios.

EL3040-EX (Enhanced Explosion-proof): 

Enhanced explosion-proof performance to meet the requirements of higher explosion-proof level in hazardous areas, 

adopting special explosion-proof design and materials to ensure safe and stable operation in flammable and explosive environments, 

which can be used for gas monitoring in hazardous areas such as petroleum and natural gas extraction.

Application Scenarios

Monitoring in the energy sector: Gas analysis is crucial in the production and use of energy. In the petrochemical industry, the Fidas24 flame ionisation detector measures hydrocarbon content and is used to monitor the gas composition in crude oil processing and natural gas transmission to ensure safe and efficient energy production and transmission. In thermal power generation, by monitoring the oxygen content in the combustion process, the combustion efficiency can be optimised, energy consumption can be reduced, and power generation efficiency can be improved.

Gas quality detection: In the process of gas production and storage, the quality of gas needs to be strictly controlled.ZO23 trace oxygen analyzer is used to measure the trace oxygen in pure gas, to ensure that the quality of high purity gases used in the electronic industry meets the requirements, and to avoid the performance and quality of electronic products being affected by impurity gas. During the storage and transport of gases, by monitoring the composition of gases, problems such as leakage can be detected in time to ensure the safety of gas storage and transport.
