火焰探測器與西門子燃燒控制器配合使用,用于燃?xì)饣蛉加突鹧娴谋O(jiān)測。
火焰探測器用于監(jiān)測燃?xì)饣鹧?、黃色或藍(lán)色燃油燃燒火焰以及點火火花的校對。

輻射探測器是一個帶 2 個電極的 UV 光電管,當(dāng)它被光譜中 190...270 nm 范圍的光照射
時便會點燃,從而啟動火焰探測器電路內(nèi)的電流。
UV 不會對燃燒室內(nèi)灼熱的耐火磚,日光或照明光線產(chǎn)生反應(yīng)。
The flame detectors are used for the supervision of gas flames, yellow- or blue-burning oil flames and for ignition spark proving.
With this type of flame supervision, the UV radiation emitted by gas or oil flames is used to generate the flame signal.
The radiation detector consists of a UV-sensitive cell with 2 electrodes, which ignite when illuminated with radiation in the 190...270 nm range of the spectrum, thereby triggering a current in the flame detector circuit.
