燃燒器專用電眼西門子火焰探測器QRA2

QRA2系列火焰探測器-電眼

品牌：SIEMENS（西門子）(原LANDIS&GYR)

型號：QRA2

產(chǎn)地：德國

火焰探測器與西門子燃燒控制器配合使用，用于燃氣或燃油火焰的監(jiān)測。

火焰探測器用于監(jiān)測燃氣火焰、黃色或藍色燃油燃燒火焰以及點火火花的校對。

這種類型的火焰探測器監(jiān)測燃氣或燃油火焰放出的 UV 輻射產(chǎn)生的火焰信號。
輻射探測器是一個帶 2 個電極的 UV 光電管，當它被光譜中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。

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 thenm range of the spectrum, thereby triggering a current in the flame detector circuit.

The UV cell does not respond to glowing firebrick in the combustion chamber, daylight or light from the boiler room illumination.
