Abstract
The utility model discloses a high sensitivity ultraviolet phototube which is characterized in that the high sensitivity ultraviolet phototube includes a glass tube shell, a cathode, an anode, metal support rods, a glass pedestal, and an exhaust tube; the metal support rods pass through the glass pedestal and are fixed on the glass pedestal; the glass tube shell is sealed with the glass pedestal to form a glass cavity; the cathode and the anode are arranged on upper ends of the metal support rods in the glass cavity; the middle part of the glass pedestal is provided with the exhaust tube. The cathode and the anode have no response to the radiation of the sunlight and an indoor lighting source, so the interference from other signals is effectively avoided. At the same time, the cathode and the anode are flat, so the area of the cathode and the anode of the phototube is bigger than the area of the cathode and the anode of a conventional metal wire, and consequently the receiving area to the ultraviolet radiation is enlarged. Besides, the high sensitivity ultraviolet phototube can perfectly prevent the misinformation caused by the natural light source and greatly improve the sensitivity to the ultraviolet radiation.
Description
Technical field
The utility model relates to a kind of device of surveying ultra-violet radiation, is specially a kind of highly sensitive ultraviolet light fulgurite that has.
Background technology
Flame radiation is to have the gas radiation of discrete spectrum and with the solid radiation of continuous spectrum, its wavelength for fear of the interference of other signals, often utilizes wavelength in 0.1 ~ 10 μ m or wideer scope<the ultra-violet radiation of 300nm, perhaps near the CO of distinctive wavelength 4.4 μ m in the flame
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, thereby can utilize it that the ultra-violet radiation in the flame is 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 one 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, and atomic weak signal is had detectability; In addition, it also has the characteristics that the reaction time is exceedingly fast.Compare with Infrared Detectors, ultraviolet detector is more reliable, and has characteristics such as high sensitivity, high output, high response speed and application circuit are simple.Thereby as the 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.The general sensitivity of ultraviolet light fulgurite of domestic production at present is at 1000cps ~ 2000cps, do not have can production sensitivity greater than the ultraviolet light fulgurite of 3000cps, this has just suppressed the development and the exploitation of the ultraviolet detector of high sensitivity, characteristics such as quick, remote.Given this, we develop a kind of high-sensitivity ultraviolet fulgurite, and sensitivity can reach 5000cps.
Summary of the invention
The purpose of the utility model is to provide a kind of can effectively prevent the wrong report that lamp causes, fast to the flame response time simultaneously, highly sensitive ultraviolet light fulgurite.
The utility model is realized through following technical scheme:
A kind of high-sensitivity ultraviolet fulgurite; It is characterized in that: comprise glass shell, negative electrode, anode, metallic struts, glass base and blast pipe; Described metallic struts runs through glass base and is fixed on the glass base; And described glass shell and glass base sealing-in form the glass chamber, and described negative electrode and anode are arranged on the upper end of the metallic struts in the glass chamber, and the middle part of described glass base also is provided with blast pipe.
Described glass base and glass shell and blast pipe are through the duration and degree of heating sealing-in.
Described metallic struts is four, circumferentially evenly is provided with, and described negative electrode is arranged on two and is on the metallic struts that the diagonal angle is provided with, and described anode then is arranged on other two and is on the metallic struts that the diagonal angle is provided with.
Described negative electrode and anode have slab construction, and laterally arrange, and the material of negative electrode and anode is for only producing photoelectric metallic nickel to being shorter than the 260nm ultraviolet radiation.
And 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: the utility model has only adopted the ultraviolet radiation that is shorter than the 260nm spectral region has been produced photoelectric negative electrode and anode; Negative electrode and anode are metallic nickel, and the glass shell adopts the molybdenum group uviol that can see through the 185nm ultraviolet radiation.Thereby, effectively avoided the interference of other signals to not response of the radiation of daylight and room lighting light source; Simultaneously; The area of negative electrode and anode increases than the anode and cathode of general ultraviolet light fulgurite to some extent; The anode and cathode of general ultraviolet light fulgurite is an one metal wire, and the utility model negative electrode and anode are dull and stereotyped, and this has just increased its receiving area to ultra-violet radiation; In addition, the utility model can also well prevent the wrong report that lamp causes and effectively improve the sensitivity to ultra-violet radiation.
