Hamamatsu Photonics所生產的UVTRON®有非常窄頻的反應,從185奈米至300奈米,並且對可見光完全沒反應。因為它使用的放電現象,其靈敏度高且輸出足夠的電壓,使得UVTRON®可以用簡單的電路設計來開發一個高靈敏度,快速響應的紫外檢測器。UVTRON®可靠地檢測來自火焰的微弱紫外線,使其成為理想的火災報警器,監控縱火,和燃燒器燃燒監控設備。UVTRON®也可以用來檢測放電現象如電暈放電。
UVTRON®is an ultraviolet ON / OFF sensor tube that uses the photoelectric effect of metal and gas multiplication effect of electric current by means of discharge. It has a very nar- row range of sensitivity from 185 nm to 300 nm and is com- pletely insensitive to visible light. Because it used the dis- charge phenomenon, its sensitive is high and an adequate output voltage is obtained, making it possible to design a high-sensitivity, quick response ultraviolet detection with sim- ple circuitry.
The UVTRON® reliably detects faint ultraviolet emissions from flames, making it ideal for applications such as fire alarms, arson surveillance, and burner combustion monitor devices. The UVTRON® can also detect discharges such as corona discharges from high-voltage power transmission lines.
