QRA2系列火焰探测器-电眼(SIEMENS)QRA2系列火焰探测器-电眼**：SIEMENS（西门子）
产地：德国
 产品介绍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 **.

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.

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

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

The detector’s UV cell is located behind a swivelling shutter at the front end of the detector tube which is flanged to the housing. A quartz glass window protects the tube and the shutter against dirt. The detector’s housing accommodates a stepper motor to drive the shutter and the electronics to control the shutter.
Using the adapter AGG16.C, this flame detector can be mounted either directly on the burner, on a viewing tube or on a combustion chamber viewing hole.
