Flame Sensors
Control device of the burners – a device that senses a flame under their control the burner, the output of which there are signals showing the presence or absence of flame. Control device of the burners is the general case of the flame detector (flame sensor) and a control unit flame sensor (secondary device). Flame sensor converts light radiation controlled flame burners into an electrical signal, and the block management processes this signal in accordance with laid down in his logic and provides a binary signal the presence or absence of controlled flame burner. Connecticut oftentimes addresses this issue. Additionally, the control unit can generate a flame sensor signal intensity of the flame in the form of 0 / 4 20 mA, and binary signals on the status of the device control the flame and binary control signals for the automatic burner control / all of the unit. Since control of the flame is directly related to safe operation of equipment, the control unit of the flame – flame sensor must accurately determine the torch of "their" torches and did not respond other torch burners and radiation of structural elements firing. (GOST 21204 -97 burner gas industry. General technical requirements: 4.2.8 Control Device flame should respond only to a controlled flame burner and should not react on foreign sources of heat and light (incandescent lining, lighting, etc.)
