style="text-indent:25px">可燃?xì)怏w報(bào)警器是如何檢測(cè)和發(fā)送報(bào)警信號(hào)？　　可燃?xì)怏w報(bào)警器檢測(cè)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(chǎng)環(huán)境以及用戶的需求而定。可燃?xì)怏w報(bào)警器檢測(cè)氣體是靠探頭來(lái)完成，探頭檢測(cè)到可燃?xì)怏w，它首先作出反應(yīng)，就是把將降氣信號(hào)轉(zhuǎn)成電信號(hào)傳送到控制器，發(fā)出報(bào)警信號(hào)，此信號(hào)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(lái)確定的，濃度越高，信號(hào)越強(qiáng)?？扇?xì)怏w報(bào)警器的工作環(huán)境和溫濕度要求？　　可燃?xì)怏w報(bào)警器對(duì)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(duì)濕度為85%RH。　　3.可燃?xì)怏w報(bào)警器安裝對(duì)檢測(cè)面積的要求？　　可燃?xì)怏w報(bào)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(wèn)題就是監(jiān)測(cè)場(chǎng)所的面積，根據(jù)面積的大小考慮安裝報(bào)警器的數(shù)量，不然報(bào)警器就是一個(gè)擺設(shè)，起不到報(bào)警的效果。如果檢測(cè)區(qū)域的面積不足20平，1個(gè)主機(jī)外加1個(gè)氣體探測(cè)器就可以滿足要求，但是如果檢測(cè)面積超過(guò)了20平米，那么主機(jī)通道和探測(cè)器的數(shù)量就要增加了。</p><p
