環氧乙烷溶(rong)液可燃氣(qi)體報(bao)警器(qi)主要(yao)有催(cui)化燃燒(shao)型(xing)、熱導型(xing)、紅外吸收型(xing)和半導體型(xing)等幾種，其中(zhong)使用最廣泛的是(shi)催(cui)化燃燒(shao)型(xing)。催(cui)化燃燒(shao)型(xing)報(bao)警器(qi)傳感器(qi)主要(yao)是(shi)由橋式電(dian)(dian)(dian)(dian)路(lu)(lu)、氣(qi)敏原(yuan)件(jian)組成。當可燃氣(qi)體進(jin)入報(bao)警器(qi)探(tan)(tan)頭(tou)，氣(qi)體與空氣(qi)中(zhong)的氧發生氧化反應，鉑絲(si)表面產(chan)生無煙催(cui)化燃燒(shao)，導致鉑絲(si)升溫(wen)，鉑絲(si)是(shi)感溫(wen)原(yuan)件(jian)，電(dian)(dian)(dian)(dian)阻值(zhi)隨溫(wen)度升高(gao)而增長，橋式電(dian)(dian)(dian)(dian)路(lu)(lu)失去平(ping)衡，產(chan)生電(dian)(dian)(dian)(dian)流，即將氣(qi)體濃(nong)度值(zhi)轉換為電(dian)(dian)(dian)(dian)信(xin)號(hao)輸出。報(bao)警器(qi)由探(tan)(tan)測器(qi)和控(kong)(kong)制(zhi)器(qi)兩部分(fen)組成，探(tan)(tan)測器(qi)即探(tan)(tan)頭(tou)傳感器(qi)部分(fen)，將氣(qi)體濃(nong)度轉換成電(dian)(dian)(dian)(dian)信(xin)號(hao)，控(kong)(kong)制(zhi)器(qi)包括控(kong)(kong)制(zhi)電(dian)(dian)(dian)(dian)路(lu)(lu)、放(fang)大(da)電(dian)(dian)(dian)(dian)路(lu)(lu)、報(bao)警系統和顯(xian)示(shi)器(qi)等部分(fen)。
