SIEMENS QRA53.E17 UV flame detector

The ultraviolet flame detector is designed for the Siemens burner control device to monitor the oil and gas flame and ignition spark. In order to ensure the free operation of the burner, these detectors continuously monitor the intensity of UV radiation of the burner flame in each half cycle, and provide signal current for the control system.

The detector UV unit is located behind the rotary baffle at the front of the detector tube, and the front of the detector tube is connected to the shell through a flange. Quartz glass windows protect pipes and louvers from dust. A hard housing accommodates a stepper motor, which drives the shutter and the electronic device controlling the shutter.

High sensitivity, the shell is made of die-cast aluminum. The ultraviolet flame detector is designed for the Siemens burner controller for the monitoring of gas or oil flame.

Flame protection device, approved for continuous operation, is used to monitor oil and gas flame in applications with ionization probe and photocell detector RAR9.

Use UV flame detector QRA2/QRA2M/QRA4/QRA4M/QRA10/QRA10M for flame protection in intermittent operation mode.
