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.
