可燃氣體報警器分類

　　按(an)照(zhao)使用(yong)環境(jing)可(ke)以分為(wei)工業用(yong)氣體報(bao)警(jing)器(qi)(qi)(qi)和(he)家用(yong)燃(ran)氣報(bao)警(jing)器(qi)(qi)(qi)，按(an)自身形態可(ke)分為(wei)固定式可(ke)燃(ran)氣體報(bao)警(jing)器(qi)(qi)(qi)和(he)便攜式可(ke)燃(ran)氣體報(bao)警(jing)器(qi)(qi)(qi)。按(an)根據工作原理分別為(wei)傳(chuan)感(gan)器(qi)(qi)(qi)原理報(bao)警(jing)器(qi)(qi)(qi)，紅外線探測報(bao)警(jing)器(qi)(qi)(qi)，高(gao)能量回(hui)收(shou)(shou)報(bao)警(jing)器(qi)(qi)(qi)。大多(duo)數使用(yong)的是傳(chuan)感(gan)器(qi)(qi)(qi)式報(bao)警(jing)器(qi)(qi)(qi)，高(gao)能量回(hui)收(shou)(shou)報(bao)警(jing)器(qi)(qi)(qi)由(you)于成本(ben)太(tai)高(gao)，現仍在開發研(yan)究中。

　　工(gong)業用(yong)(yong)固(gu)定式可(ke)燃氣(qi)(qi)體(ti)報(bao)(bao)(bao)警(jing)(jing)(jing)器(qi)(qi)(qi)由報(bao)(bao)(bao)警(jing)(jing)(jing)控(kong)制(zhi)(zhi)(zhi)器(qi)(qi)(qi)和探測(ce)(ce)器(qi)(qi)(qi)組成，控(kong)制(zhi)(zhi)(zhi)器(qi)(qi)(qi)可(ke)放置于(yu)值班室內，主(zhu)要(yao)(yao)對各監測(ce)(ce)點(dian)進行控(kong)制(zhi)(zhi)(zhi)，探測(ce)(ce)器(qi)(qi)(qi)安(an)裝于(yu)可(ke)燃氣(qi)(qi)體(ti)最易(yi)泄露的(de)地(di)點(dian)，其核心(xin)部(bu)件為(wei)內置的(de)可(ke)燃氣(qi)(qi)體(ti)傳(chuan)感器(qi)(qi)(qi)，傳(chuan)感器(qi)(qi)(qi)檢(jian)(jian)(jian)測(ce)(ce)空氣(qi)(qi)中(zhong)氣(qi)(qi)體(ti)的(de)濃(nong)度(du)(du)。探測(ce)(ce)器(qi)(qi)(qi)將傳(chuan)感器(qi)(qi)(qi)檢(jian)(jian)(jian)測(ce)(ce)到(dao)的(de)氣(qi)(qi)體(ti)濃(nong)度(du)(du)轉(zhuan)換成電(dian)(dian)(dian)信號，通過(guo)線纜傳(chuan)輸(shu)到(dao)控(kong)制(zhi)(zhi)(zhi)器(qi)(qi)(qi)，氣(qi)(qi)體(ti)濃(nong)度(du)(du)越高，電(dian)(dian)(dian)信號越強，當氣(qi)(qi)體(ti)濃(nong)度(du)(du)達到(dao)或超過(guo)報(bao)(bao)(bao)警(jing)(jing)(jing)控(kong)制(zhi)(zhi)(zhi)器(qi)(qi)(qi)設(she)置的(de)報(bao)(bao)(bao)警(jing)(jing)(jing)點(dian)時，報(bao)(bao)(bao)警(jing)(jing)(jing)器(qi)(qi)(qi)發(fa)出報(bao)(bao)(bao)警(jing)(jing)(jing)信號，并可(ke)啟動(dong)電(dian)(dian)(dian)磁(ci)閥、排(pai)氣(qi)(qi)扇等(deng)外聯設(she)備，自動(dong)排(pai)除(chu)隱患。便(bian)攜式可(ke)燃氣(qi)(qi)體(ti)報(bao)(bao)(bao)警(jing)(jing)(jing)器(qi)(qi)(qi)為(wei)手持式，工(gong)作人(ren)員可(ke)隨身攜帶，檢(jian)(jian)(jian)測(ce)(ce)不同地(di)點(dian)的(de)可(ke)燃氣(qi)(qi)體(ti)濃(nong)度(du)(du)，便(bian)攜式氣(qi)(qi)體(ti)檢(jian)(jian)(jian)測(ce)(ce)儀集控(kong)制(zhi)(zhi)(zhi)器(qi)(qi)(qi)，探測(ce)(ce)器(qi)(qi)(qi)于(yu)一體(ti)，小巧靈活。與固(gu)定式氣(qi)(qi)體(ti)報(bao)(bao)(bao)警(jing)(jing)(jing)器(qi)(qi)(qi)相比主(zhu)要(yao)(yao)區(qu)別是便(bian)攜式氣(qi)(qi)體(ti)檢(jian)(jian)(jian)測(ce)(ce)儀不能外聯其他設(she)備。家用(yong)(yong)可(ke)燃氣(qi)(qi)體(ti)報(bao)(bao)(bao)警(jing)(jing)(jing)器(qi)(qi)(qi)也可(ke)以叫(jiao)做燃氣(qi)(qi)報(bao)(bao)(bao)警(jing)(jing)(jing)器(qi)(qi)(qi)，主(zhu)要(yao)(yao)用(yong)(yong)于(yu)檢(jian)(jian)(jian)測(ce)(ce)家庭煤氣(qi)(qi)泄漏(lou)，防止(zhi)煤氣(qi)(qi)中(zhong)毒和煤氣(qi)(qi)爆炸事故的(de)發(fa)生(sheng)。
