ABB EasyLine series gas analyzer EL3020, EL3040

ABB EasyLine series gas analyzer EL3020, EL3040

Product overview

The ABB EasyLine series gas analyzer includes models EL3020 and EL3040, with software version 3.2, mainly used for continuous measurement of the concentration of individual components in gases or vapors. Among them, EL3020 is a 19 inch chassis with a protection level of IP20 and a weight of approximately 7-15 kg; EL3040 is a wall mounted chassis with a protection level of IP65 and a weight of approximately 13-21 kg.

This analyzer cannot be used to measure combustible gases/air or gas/oxygen mixtures. The stainless steel gas path and gas connection version can measure flammable gases and vapors in non hazardous environments, but special requirements must be followed; The explosion-proof version (EL3040, protection level II 3G) can measure non combustible gases and vapors in hazardous environments.

Installation preparation

Installation site and power requirements

Installation site: It needs to be installed indoors and should be as close as possible to the sampling location to ensure sufficient air circulation and avoid adverse conditions such as cold, hot, temperature changes, strong airflow, dust accumulation, corrosive atmosphere, and vibration. The installation site needs to be stable enough to withstand the weight of the analyzer, and it is recommended to install the 19 inch chassis in a cabinet or rack with sliding rails.

Climate conditions: atmospheric pressure 600-1250 hPa; The maximum relative humidity is 75%, and slight condensation is allowed; Storage and transportation temperature -25-+65 ° C, operating temperature+5-+45 ° C (Uras26 combined with other analyzers is+5-+40 ° C, Limas23 is+5-+40 ° C); The maximum altitude of the installation location is 2000 meters.

Power supply: Input voltage 100-240 V AC (-15%,+10%), 50-60 Hz (± 3 Hz); Maximum power consumption of 187 VA; using a 3-pole grounded instrument connector (EN 60320-1/C14), equipped with a power cord; The built-in clock is powered by a 3 V CR2032 lithium battery.

Sample gas conditions

Different analyzers have different requirements for the inlet and outlet conditions of the sample gas. For example, Uras26 requires the dew point of the sample gas to be at least 5 ° C lower than the lowest ambient temperature in the entire sample gas path, with a positive pressure of 2-500 hPa and a flow rate of 20-100 l/h; Limas23, Magnos206, Caldos27, etc. also have their own corresponding requirements for temperature, pressure, flow rate, etc.

Special requirements

Combustible gas measurement: EL3020 needs to ensure air circulation around it and cannot be placed directly on a table. The chassis holes must not be closed and should be at least 3 cm away from adjacent built-in components. The enclosed cabinet should have sufficient ventilation; The EL3040 chassis must be purged with nitrogen gas at a flow rate of 1-20 l/h, and the outlet flow rate of the purging gas needs to be monitored.

Explosion proof design (EL3040, protection level II 3G): The cable should be correctly inserted into the threaded cable sealing sleeve and tightened, and unused cable connectors should be sealed with suitable ventilation plugs; In hazardous areas, it is not allowed to open the chassis with electricity on; Unused purge gas connections during operation need to be sealed with ventilation plugs, etc.

Installation process

Unpacking and Inspection

Two people are required to open the box. After removing the accessories, take out the analyzer from the packaging box, remove the packaging and place it in a clean location. Check for any transportation damage and keep the packaging box and materials for future transportation.

Gas connection installation

It is recommended to install gas connections before installing the analyzer. The accessories should be clean and free of residue, and no sealant should be used. PTFE sealing tape should be used instead. Different models and combinations of analyzers have different gas connection methods, which need to be operated according to the corresponding connection diagram, such as Uras26, Limas23, and their combinations with other analyzers.

Analyzer installation

19 inch chassis (EL3020): requires 4 oval head screws (M6 recommended) and 1 pair of mounting rails (approximately 240 mm in length) to be installed in a cabinet or rack, with a minimum spacing of 1 height unit between multiple 19 inch chassis.
