1.可燃?xì)怏w報警器是如何檢測和發(fā)送報警信號可燃?xì)怏w報警器檢測原理主要有催化燃燒、紅外和熱導(dǎo)，需要根據(jù)量程、現(xiàn)場環(huán)境以及用戶的需求而定?？扇?xì)怏w報警器檢測氣體是靠探頭來完成，探頭檢測到可燃?xì)怏w，它首先作出反應(yīng)，就是把將降氣信號轉(zhuǎn)成電信號傳送到控制器，發(fā)出報警信號，此信號的不同主要是依據(jù)儀表顯示的可燃?xì)怏w下限的百分比濃度值來確定的，濃度越高，信號越強(qiáng)。 2.可燃?xì)怏w報警器的工作環(huán)境和溫濕度要求可燃?xì)怏w報警器對環(huán)境的要求也是有一定范圍的，通常工作的環(huán)境要求溫度范圍控制在（0-40）℃；相對濕度為85％RH。 3.可燃?xì)怏w報警器安裝對檢測面積的要求可燃?xì)怏w報警器要想達(dá)到預(yù)期的效果，能夠真正杜絕安全隱患，必須要考慮的問題就是監(jiān)測場所的面積，根據(jù)面積的大小考慮安裝報警器的數(shù)量，不然報警器就是一個擺設(shè)，起不到報警的效果。如果檢測區(qū)域的面積不足20平，1個主機(jī)外加1個氣體探測器就可以滿足要求，但是如果檢測面積超過了20平米，那么主機(jī)通道和探測器的數(shù)量就要增加了。無錫固定式可燃?xì)怏w報警器供應(yīng)商</p><p
