Description
Technical field
The utility model relates to a kind of ultraviolet detector, is specially the senser of ultraviolet detector, promptly a kind of inflation ultraviolet light fulgurite with day blind performance.
Background technology
Flame radiation is to have the gas radiation of discrete spectrum and with the solid radiation of continuous spectrum; Its wavelength is in 0.1 μ m～10 μ m or wideer scope; Interference for fear of other signals; Often utilize the ultra-violet radiation of wavelength, perhaps near the CO of distinctive wavelength 4.4 μ m in the flame less than 300nm
2Radiation spectrum is as detectable signal.UV sensor only responds the ultra-violet radiation in 185nm～260nm narrow range, and insensitive to the light of other spectral range, utilizes it can the ultra-violet radiation in the flame be detected.The optical wavelength that sunlight and the non-purple material that arrives atmosphere ground down sends as the electric light source of glass bulb is all greater than 300nm, so the 220nm of flame detecting～280nm middle ultraviolet band belongs to solar spectrum blind area (day blind area).The ultraviolet flame Detection Techniques make system avoid the complex background that the most powerful lamp sun causes, and make that the burden of information processing greatly alleviates in system; So reliability is higher; It is the photon detection means in addition, thereby signal to noise ratio is high, has atomic Testing of Feeble Signals ability; In addition, it also has the characteristics that the reaction time is exceedingly fast.Compare with Infrared Detectors; Ultraviolet detector is more reliable; And have characteristics such as high sensitivity, high output, high response speed and application circuit are simple, thus as the inflation ultraviolet light fulgurite of the senser of ultraviolet detector be applied to just increasingly extensively burning monitoring, fire from warning, discharge examination, UV detection, and the ultraviolet controller for electric consumption in.
Summary of the invention
The wrong report that the light wave that the purpose of the utility model is to provide a kind of sunlight that can effectively prevent to arrive ground under the atmosphere and non-purple material to send as the electric light source of glass bulb causes; Has a day blind performance; Satisfy jacking light and side simultaneously and advance two kinds of detection modes of light, the inflation ultraviolet light fulgurite of being convenient to install.
The utility model is realized through following technical scheme:
A kind of day blind type inflation ultraviolet light fulgurite; It is characterized in that: comprise stem stem, negative electrode, anode and glass shell; Described stem stem comprises glass base, metallic struts and blast pipe, and metallic struts is passed glass base and is fixed on the glass base, and blast pipe then is arranged on the centre of glass base; Described anode and negative electrode are fixed on the metallic struts top of stem stem; And anode and negative electrode in the vertical direction laterally arrange, and in addition, the above-mentioned glass shell and the glass base sealing-in of stem stem are fixed.
The glass base of described glass shell and described stem stem is through the duration and degree of heating sealing-in.
Described metallic struts is four, arranges evenly that circumferentially negative electrode is fixed on two adjacent metallic struts, and anode is fixed on other two adjacent metal poles.
Described negative electrode and anode are fixed on the metallic struts through the mode of spot welding.
The horizontal plane of the glass base of described negative electrode and anode and stem stem is 45 ° of angles.
The material of described negative electrode 3 and anode 2 produces photoelectric metallic nickel for the ultraviolet radiation that only wavelength is shorter than 260nm.
The material of described glass shell is the molybdenum group uviol that can see through the 185nm ultraviolet radiation.
The beneficial effect of the utility model is: negative electrode that the utility model adopts and anode are that a ultraviolet radiation to 185nm～260nm spectral region produces photoelectric effect; Thereby the not response of light wave that the sunlight that arrives ground under the atmosphere and non-purple material are sent as the electric light source of glass bulb; Reliability and signal to noise ratio are high, have a day blind property, and negative electrode becomes parastate with anode and horizontal by 45; Have the jacking light of detection and side simultaneously and advance luminous energy power, be convenient to install.
