The blaze detector of burner explores principle introduction

Blaze detector is one of fittings with indispensable burner, after all how does blaze detector work, the brand of blaze detector has a lot of, the burner blaze detector that uses principle of radiation light energy at present is to use for extensive, also be relatively the method of burner blaze detector of effective. The principle that intensity of radiation light energy detects is the radiation that receives blaze to give out with probe, the existence that according to its the size of intensity judges blaze. Because detect of wave band different, can divide detect for ultraviolet ray, visible light, infrared ray and total radiation blaze. Blaze explores signal to come from ultraviolet detector and smoke detector.

Blaze detector has 3 independent exploration canals, use at exploring wavelengh to be 180, 260 dust ultraviolet radiate. The radiation action when blaze when the cathode to one of exploration canals, electron beam is radiative come out. Electron beam action arrives the ionization gas that is full of exploration canal, launch a more electrons thereby, generation gives avalanche condition. More electrons are released, an instantaneous electron arises to flow between cathode and positive pole. This instantaneous electron flows (pulse) as heavy as rate of proportionate of ultraviolet radiate intensity recrudesce is unripe. The frequency of pulse is changed inside detector voltage transmits burner controller.

Ultraviolet, infra-red probe explores the spectrum of different share respectively, explore corresponding spectrum at the same time when 2 probe only when, ultraviolet, infra-red probe just can have output, avoided to use ultraviolet or infra-red probe alone so by certain reason (wait like lightning, arc welding) what cause call the police by accident. This blaze probe has two relay to output, of its breakdown relay often shut dot and terminal resistor to string together receive, be in repeatedly of blaze relay often open a dot to go up. When probe has breakdown happening, breakdown relay movement, produce one breakdown (open circuit) signal. When exploring blaze, blaze relay movement, output one alarm signal. This are ultraviolet / infra-red used automatic Oi to check a function, about one minute detects, the cleanness that checks probe camera lens is spent, the function of the sensitivity of sensor and in-house electron circuit. If all explore breakdown 3 times continuously, probe will output one fault signal. 100 get burner, the blaze detector of burner of profit elegant way also is to be based on above theory to develop outspread.
