氫氣(qi)(qi)(qi)濃度報(bao)警(jing)儀(yi)可燃氣(qi)(qi)(qi)體(ti)(ti)報(bao)警(jing)器(qi)(qi)(qi)主要有催(cui)化(hua)燃燒(shao)型(xing)、熱導型(xing)、紅外(wai)吸收型(xing)和(he)半導體(ti)(ti)型(xing)等(deng)(deng)幾種，其(qi)中(zhong)使用(yong)最廣泛的是(shi)催(cui)化(hua)燃燒(shao)型(xing)。催(cui)化(hua)燃燒(shao)型(xing)報(bao)警(jing)器(qi)(qi)(qi)傳感器(qi)(qi)(qi)主要是(shi)由(you)橋(qiao)式電(dian)(dian)(dian)(dian)路(lu)、氣(qi)(qi)(qi)敏(min)原(yuan)件組(zu)成(cheng)(cheng)。當可燃氣(qi)(qi)(qi)體(ti)(ti)進入報(bao)警(jing)器(qi)(qi)(qi)探(tan)頭，氣(qi)(qi)(qi)體(ti)(ti)與空氣(qi)(qi)(qi)中(zhong)的氧發生氧化(hua)反應，鉑(bo)(bo)絲表面產(chan)生無(wu)煙催(cui)化(hua)燃燒(shao)，導致鉑(bo)(bo)絲升溫，鉑(bo)(bo)絲是(shi)感溫原(yuan)件，電(dian)(dian)(dian)(dian)阻值(zhi)隨溫度升高而(er)增長，橋(qiao)式電(dian)(dian)(dian)(dian)路(lu)失去平(ping)衡(heng)，產(chan)生電(dian)(dian)(dian)(dian)流，即(ji)將氣(qi)(qi)(qi)體(ti)(ti)濃度值(zhi)轉換(huan)為電(dian)(dian)(dian)(dian)信號輸出。報(bao)警(jing)器(qi)(qi)(qi)由(you)探(tan)測(ce)器(qi)(qi)(qi)和(he)控(kong)(kong)制器(qi)(qi)(qi)兩部分(fen)(fen)組(zu)成(cheng)(cheng)，探(tan)測(ce)器(qi)(qi)(qi)即(ji)探(tan)頭傳感器(qi)(qi)(qi)部分(fen)(fen)，將氣(qi)(qi)(qi)體(ti)(ti)濃度轉換(huan)成(cheng)(cheng)電(dian)(dian)(dian)(dian)信號，控(kong)(kong)制器(qi)(qi)(qi)包(bao)括(kuo)控(kong)(kong)制電(dian)(dian)(dian)(dian)路(lu)、放大電(dian)(dian)(dian)(dian)路(lu)、報(bao)警(jing)系統和(he)顯示器(qi)(qi)(qi)等(deng)(deng)部分(fen)(fen)。
