UVTRON 是紫外線開/關(guān)探測器，可快速遠(yuǎn)距離檢測火焰發(fā)出的微弱 UV，因而適合用于火焰探測器和火警。它們的光譜靈敏度范圍是 185 nm 到 300 nm，且對(duì)可見光完全不敏感。它們使設(shè)計(jì)具有簡單電路的高靈敏度、快速響應(yīng)的 UV 檢測系統(tǒng)成為可能。

Operating principle

When UV light emitted from flames or discharges reaches the UVTRON and strikes the cathode, photoelectrons are released from the cathode surface. These photoelectrons are drawn toward the anode while colliding with gas molecules and ionize them, producing secondary electrons. The electrons then repeatedly collide with and ionize other gas molecules until finally reaching the anode. By using this phenomenon called gas multiplication, UVTRON amplifies the electrical current and outputs it as a signal.

主要型號(hào)有R2868、R9454、R9533、R13192等。

主要應(yīng)用場合如下：包括大型復(fù)雜設(shè)施和倉庫中的火警、鍋爐火焰監(jiān)測、氫火焰檢測（氫作為一種新能源正在引起廣泛關(guān)注）以及一般行業(yè)的其他任務(wù)。
