QRA2 ultraviolet flame detector, normal sensitivity, without flange/clamp


QRI flame detector: The extrauterine flame detector used in Siemens burner controller is used to monitor gas flame, fuel flame and other flame that can be detected by infrared distribution.

QRI can be put into the burner and run in continuous or intermittent mode with any power.

QRI features: ① infrared flame detector with infrared sensitive flame sensor ② integrated flame signal amplifier ③ forward and lateral (90 °) lighting design ④ suitable for burner controller LMV5 series ⑤ fixed on burner through flange and clamp; QRI can be used with suitable burner controller through electronic self-monitoring of flame signal, and can realize continuous or intermittent operation; The sensitivity of QRI is designed for use behind the burner baffle.

Siemens flame detector

Siemens original off-the-shelf, infrared photo-eye QRI2 detects infrared ray, which is used to detect yellow flame, that is, infrared ray in flame, and can be used for fuel flame safety detection. QRI2A2.B180B is used in conjunction with Siemens program controller, which can be used for large burner, continuous or intermittent operation.

Infrared flame detection.

QRI2B2.B180B Siemens flame detector

Flame signal amplifier.

There are two kinds of front detection and side detection.

Automatic patrol function.

Not limited by burner load.

It is not limited by operation mode.

Installation, assembly and service shall be completed by professional personnel

Before making any line changes in the connection area of the detector, the equipment should be completely isolated from the main power supply (all two levels are disconnected).

Provide proper protection for the connection terminal to ensure that it is not subject to electric shock. Check and confirm that the line is connected correctly.

Check and confirm that the line is connected correctly. Halogen lamps, welding equipment, special lamps or ignition sparks may generate enough radiation to ignite the UV unit of the detector. X-rays and gamma rays can also cause false flame signals.

Falling or hitting will affect the safety function. Such detector units cannot work, even if their appearance appears to be damaged at all.
