The flame sensor (Photocell) QRA2. UV sensor for flame control of combustion gas or the combustion of liquid fuel. Flame detectors QRA2 designed to operate in conjunction with combustion machines Siemens
Flame detector QRA2 Siemens used in heating equipment of high power, using blast (supercharged) burners (Cib unigas, Giersch,Weishaupt, etc.), along with ionization sensors are sensitive to radiation of the burner flame in the infrared, ultraviolet or visible (photosensors) region of the spectrum. Such sensors are also used when the installation of an ionization sensor for combustion equipment simply is not the place.
The effectiveness of flame control infrared sensors decreases due to heat radiation from the heated surfaces of the furnace. The most reliable are UV sensors. Adjusting them to different (temperature and spectrum of light) part of the flame, it is possible to achieve satisfactory control even with a fluctuating feed of fuel. The use of ultraviolet, infrared and photo-sensors also require power supply from the external network and provides logic control of the combustion process.
Is responsible for what the flame sensor Qra2 ?The flame sensor is responsible for control of fuel delivery, and when you stop he gives a signal and the burner is blocked and the fuel supply stops.
On any burners is the flame sensor qra2, Siemens?Photocell qra is used in most European burners, among them leaders such as Oilon (Finland), Cib unigas (Italy), Weishaupt (Germany), Riello (Italy), Baltur (Italy), Giersch (Germany) and Elco (Italy), Cuenod (Italy)
