BST KLC11 - Dual Fuel UV Universal Flame Detector

UV - flame detector KLC 11 for oil - gas and dual fuel burners for intermittent burner operations

The KLC 11 is a compact UV flame detector, which has been developed for single flame combustion which produces little light or radiation in the visible spectrum and has very low flame modulation/flicker frequency. The design of the UV sensor ensures that the flame detector does not react to background radiation from hot refractory or from any other infra-red light source.

The flame detector is equipped with an optical interface which visibly indicates the flame signal intensity. The KLC 11 can be connected directly to the ionisation or LDR input of the control box. It is compatible in its physical dimensions and connection capability to other series KLC flame detectors. All KLC accessories are identical and therefore this reduces the variety of components used in production and makes it simpler for field application and service.

The flame detector KLC 11 has been developed to meet the requirements of European Standards EN298:2012-11. The internal increase of the UV tube voltage immediately after apply supply voltage ensures the safety requirement in accordance with the EN298:2012-11 for the examination of the UV tube to through-ignition. A simple change from ionisation flame control to the KLC 11 is permissible therefore also with control boxes without own UV tube input.
