As shown in Figure 1, 2, a kind of explosive flame sensor, including base 1, upper cover 3 and the window structure of tubular, described on
Lid is connected formation one cavity with base, is provided with the first sealing ring 2 playing sealing function between described base and upper cover.Upper cover and
Base uses threaded and locks with marking closely screw, prevents from loosening, improves the comprehensive sealing performance of shell.
Under far ultraviolet irradiation in explosive flame, the incident far ultraviolet of Electron absorption in double ultraviolet light induced module photocathodes
The energy of photon and escape photocathode surface, to anode movement under cathode electric field effect, thus produce the signal of telecommunication, through oversampling circuit mould
The process transport of block, exports the signal of telecommunication, reaches to detect the purpose of explosive flame.Logical light window is used for detonation by influence flame ultraviolet band,
And prevent external impurities from entering sensor internal.The spectral response of the ultraviolet light photo induction module used is 185～260nm, far
The scope of ultraviolet light, the ultraviolet band of sunlight terminates in that 290nm, infrared band terminate in 13um, therefore this ultraviolet phototube
Insensitive to sunlight.The spectral band of illumination light-emitting is from the beginning of 300nm, not within the investigative range of Ultraviolet sensor, because of
This this explosive flame sensor capacity of resisting disturbance is strong.
Double ultraviolet induction modules are used for detonation by influence flame information, when two ultraviolet phototubes all detect explosive flame ultraviolet light,
The signal of telecommunication can be converted into.
