Description Vendor

The D-LE 603 Flame Sensor is a specialized device designed for monitoring gas, oil, and coal flames, primarily in multi-burner applications. It features self-monitoring and fail-safe capabilities when integrated with a control unit or burner control, ensuring reliable operation in hazardous environments. The sensor is available with different photo elements to maximize selectivity across various fuels and is ATEX approved for use in hazardous areas. It connects to control units such as D-UG 120, D-UG 660, and D-GF 150, making it suitable for applications in power stations, chemical industry, refineries, cement plants, waste incinerators, steam generators, and heating plants. The sensors output signal is proportional to the flame radiation intensity and is used as an input signal to a control unit or burner control. It is also compatible with various test light sources and accessories for optimal alignment and performance.

Use Cases

  • Power stations
  • Chemical industry
  • Refineries
  • Cement plants
  • Waste incinerators
  • Steam generators
  • Heating plants
  • Hydrogen burner monitoring (100% H2 or H2-mix fuels)

Capabilities

  • Self-monitoring and fail-safe in conjunction with a control unit/ burner control
  • Flame sensors for every spectral range from UV to IR
  • Connection to the D-UG 120 control unit, D-UG 660 control unit as well as to the D-GF 150 (-MB) burner control
  • Uniform output signal thus mutually interchangeable
  • Adjustable to different combustion technologies such as exhaust gas recirculation
  • Compliance to general safety regulations
  • ATEX approved
DURAG GROUP DURAG GROUP, a German gas analysis and measurement technology company, supports hydrogen purity monitoring through its subsidiary AP2E's ProCeas gas analyzers, which have been developing hydrogen industry solutions since 2015 and participated in the EU-funded MetroHyVe research project for controlling hydrogen purity per ISO 14687:2019. The ProCeas gas analyzer, based on patented OFCEAS (Optical Feedback Cavity Enhanced Absorption Spectroscopy) technology combined with low-pressure sampling (LPS), monitors trace-level impurities such as CO, HCHO, NH3, H2S, COS, and H2O at hydrogen refueling stations, providing real-time contaminant detection compliant with ISO 14687, EN 17124, ISO 19880, and Northern Lights CCUS specifications with no drift and no recalibration required. SGS France's laboratory in Harfleur uses ProCeas devices to monitor hydrogen purity for mobility applications (grade D, 99.97% purity), quantifying 14 different impurities from ppb to ppm levels in a single sample injection. DURAG GROUP also provides H2-ready combustion control and safety solutions including customized burners, igniters, flame scanners supporting up to 100% hydrogen fuel mixtures, and video/thermography monitoring systems for safe, reliable operation with complex and variable fuel mixtures.
