可燃气体报警器有哪几种分类?
当工业环境、日常生活环境中存在可燃性气体的场所,都需要安装可燃气体报警器。可燃气体报警器主要用于检测空气中的可燃气体,常见的如氢气(H2)、甲烷(CH4)、乙烷(C2H6)、丙烷(C3H8)、丁烷(C4H10)、乙烯(C2H4)、丙烯(C3H6)、丁烯(C4H8)、乙炔(C2H2)、丙炔(C3H4)、丁炔(C4H6)、磷化氢(PH3)等。当空气中检测到可燃性气体浓度达到可燃气体报警器设置的报警值时,可燃气体报警器就会发出声、光报警信号。那么您知道可燃气体报警器有哪几种分类吗?下面逸云天小编为您介绍:

可燃气体报警器按不同方式分类,可分为以下几种:
一、按功能:
可分为可燃气体探测器、可燃气体报警器、可燃气体报警器和可燃气体检测报警器
二、按用途分:
(1)固定式:探测器和可燃气体报警器分开安装,前者安装在工作现场,后者安装在仪器监控室。
(2)便携式:检测元件和可燃气体报警器一体成型,由巡检人员带到工作现场。
三、按使用环境分:
工业可燃气体报警器、家用可燃气体报警器
四、按检测原理分类:
(1)催化燃烧型:利用难熔金属铂丝加热后电阻变化用于测量可燃气体的浓度,催化燃烧式可燃气体报警器一般用于检测石油气、煤气、汽油、煤气、甲烷、乙炔、氢气等可燃气体,其优点是重复性好、功耗低。
(2)半导体型(气敏型)型):可燃气体报警器采用灵敏度较高的气敏半导体元件,整机体积小,电路比较简单,非常适合检测。氢气、甲烷、乙醇、天然气等都非常敏感。这种可燃气体报警器灵敏度高,无催化剂中毒问题,仪器使用寿命长。
综上所述,就是可燃气体报警器按不同方式所划分出来的分类。大家在选择可燃气体报警器时,可以根据实际需求的不同来选择合适的可燃气体报警器,这样选择的可燃气体报警器才更适合您进行使用。
