Abstract:
Embodiments relate generally to systems and methods for detecting obscuration of a window of a flame detector. A flame detector may comprise a housing; a window attached to the housing, wherein the window allows radiation to pass through to the interior of the housing; a transmitter configured to emit electromagnetic radiation; a receiver configured to receive electromagnetic radiation emitted by the transmitter; and a plurality of angled surfaces configured to direct the electromagnetic radiation from the transmitter through at least a portion of the window and toward the receiver.
