Product Overview

The ABB EL3040 featuring the URAS-26 infrared photometer is a high-precision solution for continuous gas analysis in complex industrial environments. This rack-mounted analyzer is engineered to detect and quantify multiple gas components simultaneously, including Carbon Monoxide, Sulfur Dioxide, and Methane, among others. By utilizing advanced NDIR (Non-Dispersive Infrared) technology, the URAS-26 delivers exceptional selectivity and long-term stability. The system is housed in a robust 19-inch enclosure, making it an ideal choice for integration into standardized monitoring cabinets where reliable, real-time data is critical for process safety and environmental compliance.

Essential Performance Metrics and Physical Data

• Repeatability performance of ±1% of the current measured value.

• Zero and Span drift maintained at less than 1% per week for reduced calibration frequency.

• Inlet sample gas pressure tolerance ranging from 800 to 1200 hPa.

• Optimal sample gas flow rate set between 0.5 and 1.5 L/min.

• Operating ambient temperature range of -5°C to +45°C.

Strategic Industrial Deployment

The EL3040 URAS-26 is predominantly utilized in sectors where emission monitoring and combustion control are paramount. In power generation and waste incineration plants, it serves as a primary tool for Continuous Emissions Monitoring Systems (CEMS) to ensure SO2 and NO levels remain within legal limits. It is equally effective in the chemical processing industry for purity analysis and safety monitoring of flammable or toxic gases. Beyond heavy industry, this analyzer finds application in iron and steel manufacturing for blast furnace gas analysis and in cement production to optimize fuel efficiency by monitoring exhaust gas composition.

FAQ

Q: Does the EL3040 URAS-26 support multi-component analysis within a single unit?

A: Yes, the URAS-26 photometer is capable of measuring up to four infrared-active gas components simultaneously, providing a compact solution for multi-gas monitoring requirements.

Q: What are the primary maintenance requirements for this analyzer?

A: Maintenance involves periodic zero and span calibrations, typically once a week or month depending on accuracy needs, and checking the internal filters to ensure sample gas remains free of particulates.

Q: Can this unit be installed in outdoor environments?

A: The housing is rated IP20 and designed for 19-inch rack mounting inside a protected enclosure or control room. For outdoor use, an additional climate-controlled protective cabinet is necessary.

Q: What communication protocols are available for DCS integration?

A: The device is highly versatile, supporting standard 4-20 mA analog outputs as well as digital communication via Modbus and Profibus for seamless integration with modern Distributed Control Systems.

Q: How does the unit handle variations in sample gas temperature?

A: The EL3040 can process sample gases up to 50°C. If your process gas exceeds this temperature, a sample conditioning system must be used to cool and dry the gas before it enters the analyzer.
