Fire Sentry SS4/FSC紫外/红外火焰探测器

Honeywell在2011年底收购的fire sentry公司利用出众的火焰探测技术用于所有火焰探测产品的设计与制造，此技术早在1884年就开始应用，并且有军工、航空领域技术背景。fire sentry火焰探测器利用专利的宽频红外量子传感器，FS24三重红外火焰探测器使用宽频4.3微米红外技术的局限性。SS4-A型光电火焰探测仪采用UV/IR探测技术并成功应用于全世界数千处场合中。

·Multi-Spectrum可探测紫外、可见及红外光光谱
·内置“through the lens”自检测试
·误报警屏蔽
·探测所有火灾，不仅仅是碳氢和非碳氢类火灾
·可调探测精度
·运行于大范围温度范围内

应用范围
·碳氢类火焰探测：CH4、C2H6...
·非碳氢类火焰探测：SiH4、H2...
·其他火焰探测：酒精、IPA...
