Kromschroeder UVS5 (84333010) UV flame sensor

Krom schroder UVS5 84333010 UV-sensitive is designed specifically for overseeing flame dynamics in gas burners. It operates exclusively when paired with Elster Kromschroder automatic burner control units IFS, IFD, PFS, or PFD, as well as flame detectors IFW or PFF, or burner control units BCU or PFU. This collaborative integration ensures precise flame control and enhances the safety and efficiency of gas burner systems.

Kromchroeder UVS5 84333010 flame detector installation

Please observe the following to ensure that Krom schroder 84333010 UVS5 UV-sensitive detector is not damaged during installation:

• Use Kromschroder UVS5 84333010 flame detector only in conjunction with Elster Kromschroder automatic burner control units, flame detectors or burner control units.
• Cool Kromschroeder UVS5 84333010 UV-sensitive detector with filtered air when subject to higher temperatures. In addition, this protects the sensor from dirt and condensation.
• Max. distance between Krom schroder UVS5 84333010 flame detector and flame < 400 mm.
• It can be fitted using a 1/2” viewing tube that should be aligned on the first flame third, as this is where the highest UV radiation is generally found. The inside of the steel tube should not be coated and the tube should be directed at the flame from above so that no dirt collects in front of the UV sensor.
• Kromschroeder 84333010 UVS5 UV cell may only be exposed to the UV light of its own flame. It should be protected from other sources of ultraviolet light, e.g. neighboring flames (this must be observed when monitoring pilot and main burners in particular), ignition sparks, arcs from welding devices or lamps emitting ultraviolet light.
• Do not expose Krom schroder 84333010 UVS5 UV sensor viewing opening to direct sunlight.
• Supply cooling air to cool and protect the optical system from soiling and condensation.
• Max. cable length in accordance with the specifications for automatic burner control units IFS, PFS, PFD, flame detectors IFW, PFF or burner control units BCU, PFU.
