?Honeywell在2011年底收購的fire sentry公司利用出眾的火焰探測技術(shù)用于所有火焰探測產(chǎn)品的設(shè)計與制造，此技術(shù)早在1884年就開始應(yīng)用，并且有軍工、航空領(lǐng)域技術(shù)背景。fire sentry火焰探測器利用專利的寬頻紅外量子傳感器，F(xiàn)S24三重紅外火焰探測器使用寬頻4.3微米紅外技術(shù)的局限性。SS4-A型光電火焰探測儀采用UV/IR探測技術(shù)并成功應(yīng)用于全世界數(shù)千處場合中。

?·Multi-Spectrum可探測紫外、可見及紅外光光譜
·內(nèi)置“through the lens”自檢測試
·誤報警屏蔽
·探測所有火災(zāi)，不僅僅是碳氫和非碳氫類火災(zāi)
·可調(diào)探測精度
·運行于大范圍溫度范圍內(nèi)

?應(yīng)用范圍
·碳氫類火焰探測：CH4、C2H6...
·非碳氫類火焰探測：SiH4、H2...
·其他火焰探測：酒精、IPA...
