Claims (4)
- 火炎が発する光または電磁波を検出するセンサと、
当該センサに設定強度の光または電磁波を照射する発光手段と、
前記センサからの信号を解析する信号処理装置と、
前記発光手段を駆動させる発光手段駆動用ドライバの各機器を備え、さらに、
火炎が無いときは、前記発光手段からの光を解析した前記信号処理装置の出力から前記各機器の健全性を診断し、火炎があるときは、火炎からの光と前記発光手段からの光とを重ね合わせた光を解析した前記信号処理装置の出力変化から前記各機器の健全性を診断する判定器を備えた火炎検出装置。 - 前記発光手段が、UV−LEDであることを特徴とする請求項1記載の自己診断機能を有する火炎検出装置。
- 前記センサが、SiC,GaN,GaP,ダイアモンドのいずれかであることを特徴とする請求項1または2記載の自己診断機能を有する火炎検出装置。
- 燃焼装置からの火炎発光から発生するパワ−スペクトルと異なるパワ−スペクトルの発光を前記発光手段で発光させることにより、燃焼装置運転中または休止中に関係なく火炎検出装置の健全性を診断することが可能な請求項1〜3のいずれかに記載の自己診断機能を有する火炎検出装置。
