SS4紫外紅外火焰探測(cè)器 優(yōu)勢(shì)供貨

Fire Sentry SS4/FSC紫外/紅外火焰探測(cè)器

Honeywell在2011年底收購(gòu)的fire sentry公司利用出眾的火焰探測(cè)技術(shù)用于所有火焰探測(cè)產(chǎn)品的設(shè)計(jì)與制造，此技術(shù)早在1884年就開(kāi)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(cè)器利用專(zhuān)利的寬頻紅外量子傳感器，F(xiàn)S24三重紅外火焰探測(cè)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(cè)儀采用UV/IR探測(cè)技術(shù)并成功應(yīng)用于全世界數(shù)千處場(chǎng)合中。

·Multi-Spectrum可探測(cè)紫外、可見(jiàn)及紅外光光譜
·內(nèi)置“through the lens”自檢測(cè)試
·誤報(bào)警屏蔽
·探測(cè)所有火災(zāi)，不僅僅是碳?xì)浜头翘細(xì)漕?lèi)火災(zāi)
