DURAG integrated flame detector

Germany DURAG GROUP-Durag Group, a well-known supplier of measurement and control equipment. Founded in 1948, it is located in the German port city of Hamburg.

DURAG GmbH is the core company of DURAG Group. It mainly produces flame detectors, high-energy ignition devices, dust meters, turbidity meters, traffic tunnel monitoring equipment, flue gas flow meters, atmospheric environment detection and management systems, etc.

The DURAG Group of Companies has the following subsidiaries:

• Hegwein Company, mainly produces oil and gas igniters, burners, oil guns and ignition devices;

• VEREWA Company, which mainly produces environmentally friendly instruments, such as small-range dust meters, mercury analyzers, etc.;

• SMITSVONK Company, mainly produces automatic ignition systems for exhaust emissions from chemical plants and steel plants.

DURAG products have been widely used in the power industry and other process industries, such as coal-fired power plants, waste incinerators, purification plants, chemical plants, cement plants, steel plants and filtration systems.

Working principle of DURAG flame detector:

The flame is detected by detecting the special wavelengths of ultraviolet, infrared and visible light radiated by the flame, and at the same time identifying the characteristic flicker frequency of the flame. When the flame burns, it will release ultraviolet, infrared and other radiation of specific wavelengths and frequencies. The photoelectric detector in the detector uses the photoelectric effect to convert these optical radiation into electrical signals. After processing and analysis by the internal circuit, it determines whether there is a flame and outputs the flame intensity signal as a 4-20mA analog signal.

High reliability: Using advanced optical and electronic technology, it has high detection accuracy and stability, and can work reliably in complex industrial environments.
