产地：德国
产品描述
和西门子燃烧控制器火焰探测器使用气体或油进行火焰监测。
火焰探测器，用于监测气体火焰，黄色或蓝色燃烧的油火焰和点火火花证明。
这种类型的火焰探测器监测气体或油火焰发出的紫外线辐射产生的火焰信号。
是一种具有两个电极的辐射探测器，当它处于光照射的190-270nm光谱范围内时具有UV光电池
何时会点火，从而启动当前火焰探测器电路。
UV在燃烧室中不发光的耐火砖，日光或照明光反应。

QRA53和QRA55系列适合连续工作24小时
火焰探测器QRA5结构设计如下：

UV检测器单元位于旋转快门后面，在前端位置的快门被法兰连接到检测器管的外壳。石英玻璃窗百叶窗保护管道免受污垢和损坏。在电机驱动的检测器内部并控制快门。使用AGG16C适配器，火焰探测器可直接安装在燃烧器或燃烧室观察孔观察孔上。

Flame detector for SIEMENS QRA55C27 220-240V 50/60HZ

QRA53E27 replace the original QRA53C27 flame detector - electric eye
Brand: SIEMENS (Siemens) (formerly LANDIS & GYR)
Origin: Germany
product description
And Siemens combustion controller flame detector with the use of gas or oil for flame monitoring.
Flame detectors for monitoring gas flames, yellow- or blue-burning oil flames and for ignition spark proving.
This type of flame detectors to monitor gas or oil flames emitted UV radiation produced by the flame signal.
Is a radiation detector with two electrodes UV photocell, when it was in the 190 - 270nm spectral range of the light irradiation
When will ignite, thus starting current flame detector circuit.
UV does not glowing firebrick in the combustion chamber, daylight or illumination light reacts.

QRA53 and QRA55 series are suitable for continuous operation 24 hours
Flame detectors QRA5 structural design as follows:

UV detector unit is located behind a rotating shutter, the shutter at the front end position is flanged to the housing of the detector tube. A quartz glass window shutter to protect the pipe from dirt and damage. Inside the detector for motor drive and control the shutter. Use AGG16C adapter, flame detectors can be mounted directly to the burner or the combustion chamber viewing hole on a viewing tube.
