六氟(fu)化硫有毒么可(ke)燃氣(qi)體(ti)(ti)報(bao)警器(qi)(qi)主(zhu)(zhu)要(yao)有催化燃燒(shao)型(xing)(xing)(xing)、熱導(dao)型(xing)(xing)(xing)、紅外吸收型(xing)(xing)(xing)和半(ban)導(dao)體(ti)(ti)型(xing)(xing)(xing)等幾種，其中使用最廣泛的(de)(de)是催化燃燒(shao)型(xing)(xing)(xing)。催化燃燒(shao)型(xing)(xing)(xing)報(bao)警器(qi)(qi)傳感器(qi)(qi)主(zhu)(zhu)要(yao)是由(you)橋式(shi)電(dian)(dian)路(lu)(lu)(lu)、氣(qi)敏原件(jian)組(zu)成。當可(ke)燃氣(qi)體(ti)(ti)進(jin)入報(bao)警器(qi)(qi)探(tan)頭(tou)，氣(qi)體(ti)(ti)與空(kong)氣(qi)中的(de)(de)氧發生(sheng)氧化反應，鉑絲(si)表面產生(sheng)無煙催化燃燒(shao)，導(dao)致鉑絲(si)升(sheng)溫(wen)，鉑絲(si)是感溫(wen)原件(jian)，電(dian)(dian)阻值(zhi)隨溫(wen)度(du)升(sheng)高而增長，橋式(shi)電(dian)(dian)路(lu)(lu)(lu)失去平(ping)衡，產生(sheng)電(dian)(dian)流，即將(jiang)氣(qi)體(ti)(ti)濃度(du)值(zhi)轉(zhuan)(zhuan)換(huan)為電(dian)(dian)信(xin)號輸出(chu)。報(bao)警器(qi)(qi)由(you)探(tan)測器(qi)(qi)和控(kong)制器(qi)(qi)兩部分組(zu)成，探(tan)測器(qi)(qi)即探(tan)頭(tou)傳感器(qi)(qi)部分，將(jiang)氣(qi)體(ti)(ti)濃度(du)轉(zhuan)(zhuan)換(huan)成電(dian)(dian)信(xin)號，控(kong)制器(qi)(qi)包(bao)括控(kong)制電(dian)(dian)路(lu)(lu)(lu)、放大電(dian)(dian)路(lu)(lu)(lu)、報(bao)警系(xi)統和顯(xian)示器(qi)(qi)等部分。
