目前現(xian)階段目前市面(mian)上的(de)火(huo)(huo)焰(yan)探(tan)(tan)(tan)測器按方(fang)法分為可見(jian)光火(huo)(huo)焰(yan)探(tan)(tan)(tan)測器、紅(hong)外(wai)(wai)感應火(huo)(huo)焰(yan)探(tan)(tan)(tan)測器和(he)紫(zi)外(wai)(wai)光火(huo)(huo)焰(yan)探(tan)(tan)(tan)測器。火(huo)(huo)焰(yan)探(tan)(tan)(tan)測器主要是一種檢測柴油發動機發動機燃(ran)燒室或燃(ran)燒機中是否存在火(huo)(huo)焰(yan)的(de)實驗(yan)儀器。它(ta)重要由紫(zi)外(wai)(wai)線(xian)傳感器和(he)控(kong)制(zhi)器組成。它(ta)應用廣(guang)泛，是目前比較有效的(de)燃(ran)燒機火(huo)(huo)焰(yan)檢測方(fang)法。

對(dui)這類類型的(de)火(huo)焰探測器進(jin)行差(cha)異分析：

1紫外線火焰探測器

紫(zi)外(wai)線(xian)火焰(yan)探測器(qi)采(cai)用紫(zi)外(wai)光(guang)敏管(guan)作為傳感器(qi)技術電子(zi)器(qi)件，其光(guang)譜分析儀范圍在0.006～0.1m正(zheng)中(zhong)間，紫(zi)外(wai)光(guang)敏管(guan)為固態脈沖(chong)(chong)電子(zi)器(qi)件，其信號(hao)為脈沖(chong)(chong)頻率與紫(zi)外(wai)線(xian)放射性(xing)物質頻率成正(zheng)比的隨意脈沖(chong)(chong)。紫(zi)外(wai)光(guang)敏管(guan)有兩個電極(ji)(ji)，一般采(cai)用高交流(liu)電路(lu)。當放射性(xing)物質到電極(ji)(ji)上的紫(zi)外(wai)光(guang)充裕強時，電極(ji)(ji)正(zheng)中(zhong)間會(hui)導(dao)致“山(shan)崩”脈沖(chong)(chong)電總流(liu)量，其頻率與紫(zi)外(wai)線(xian)抗壓強度有關，做到幾(ji)千HZ。滅火時沒有脈博(bo)。

2可見光火焰探測器

可(ke)見光(guang)(guang)(guang)(guang)火焰探測器(qi)采用光(guang)(guang)(guang)(guang)電二極管作(zuo)為傳感器(qi)技術電子器(qi)件，其光(guang)(guang)(guang)(guang)譜分析儀答復范圍(wei)在0.33～0.7正中間m、 可(ke)見光(guang)(guang)(guang)(guang)火焰探測器(qi)由監(jian)控(kong)攝(she)像頭(tou)、底盤和制冷設備組成。爐內火焰中的(de)(de)可(ke)見光(guang)(guang)(guang)(guang)依據監(jian)控(kong)攝(she)像頭(tou)尾部的(de)(de)眼鏡片，依據光(guang)(guang)(guang)(guang)纖到(dao)達監(jian)控(kong)攝(she)像頭(tou)室，照(zhao)射在光(guang)(guang)(guang)(guang)電二極管上。

光電(dian)(dian)(dian)(dian)二(er)極管將可見(jian)光信(xin)號(hao)轉換(huan)(huan)為(wei)電(dian)(dian)(dian)(dian)總(zong)流(liu)(liu)量(liang)信(xin)號(hao)，電(dian)(dian)(dian)(dian)總(zong)流(liu)(liu)量(liang)信(xin)號(hao)依(yi)據(ju)大(da)部(bu)分(fen)變(bian)大(da)儀(yi)轉換(huan)(huan)為(wei)工作標準電(dian)(dian)(dian)(dian)壓(ya)(ya)信(xin)號(hao)。大(da)部(bu)分(fen)變(bian)大(da)儀(yi)輸(shu)出的(de)工作標準電(dian)(dian)(dian)(dian)壓(ya)(ya)信(xin)號(hao)被傳輸(shu)變(bian)大(da)儀(yi)轉換(huan)(huan)成電(dian)(dian)(dian)(dian)總(zong)流(liu)(liu)量(liang)信(xin)號(hao)。接著依(yi)據(ju)屏蔽雙(shuang)絞線傳輸(shu)到電(dian)(dian)(dian)(dian)腦(nao)主機箱。在這(zhe)里類(lei)情況(kuang)下(xia)，電(dian)(dian)(dian)(dian)總(zong)流(liu)(liu)量(liang)信(xin)號(hao)被轉換(huan)(huan)成工作標準電(dian)(dian)(dian)(dian)壓(ya)(ya)信(xin)號(hao)。將代表著火焰(yan)的(de)工作標準電(dian)(dian)(dian)(dian)壓(ya)(ya)信(xin)號(hao)分(fen)別送(song)至(zhi)頻率檢測(ce)(ce)電(dian)(dian)(dian)(dian)路(lu)、抗(kang)拉(la)(la)強度(du)檢測(ce)(ce)電(dian)(dian)(dian)(dian)路(lu)和常見(jian)問題檢測(ce)(ce)電(dian)(dian)(dian)(dian)路(lu)。抗(kang)拉(la)(la)強度(du)檢測(ce)(ce)電(dian)(dian)(dian)(dian)路(lu)有兩個不一樣的(de)極限(xian)，即限(xian)定(ding)和下(xia)限(xian)。當(dang)火焰(yan)抗(kang)拉(la)(la)強度(du)超過限(xian)定(ding)時，抗(kang)拉(la)(la)強度(du)燈亮，說明(ming)(ming)著火；當(dang)火焰(yan)抗(kang)拉(la)(la)強度(du)低于低特惠，抗(kang)拉(la)(la)強度(du)燈消滅，說明(ming)(ming)滅火。

火(huo)(huo)焰頻(pin)率檢測電(dian)(dian)(dian)路(lu)用于火(huo)(huo)焰閃(shan)爍檢測。根據火(huo)(huo)焰的閃(shan)爍頻(pin)率是否(fou)高過或低于設定(ding)的頻(pin)率，可以適當辨別爐內是否(fou)有火(huo)(huo)焰。常(chang)見(jian)(jian)問題(ti)檢測電(dian)(dian)(dian)路(lu)也是有兩(liang)個限(xian)(xian)制。一(yi)切正(zheng)常(chang)情況(kuang)下(xia)，該值保持在限(xian)(xian)定(ding)和下(xia)限(xian)(xian)正(zheng)中間。一(yi)旦電(dian)(dian)(dian)腦(nao)主(zhu)機(ji)箱的信號(hao)輸入電(dian)(dian)(dian)路(lu)造(zao)成(cheng)常(chang)見(jian)(jian)問題(ti)，如光電(dian)(dian)(dian)管到電(dian)(dian)(dian)腦(nao)主(zhu)機(ji)箱的電(dian)(dian)(dian)纜斷(duan)了，上述(shu)工(gong)作標準電(dian)(dian)(dian)壓信號(hao)立(li)刻偏(pian)位一(yi)切正(zheng)常(chang)范圍(wei)，傳來(lai)常(chang)見(jian)(jian)問題(ti)報警設備(bei)。

三(san)。紅外感應火焰探測(ce)器

紅外(wai)感(gan)應火(huo)(huo)焰(yan)(yan)探測器采用硫化(hua)鉛(qian)或硫化(hua)鎘光(guang)刻工藝(yi)作(zuo)為傳感(gan)器技術電(dian)(dian)子器件，其光(guang)譜(pu)分析(xi)儀(yi)(yi)答(da)復范圍在0.7-3.2中間(jian)、 紅外(wai)感(gan)應火(huo)(huo)焰(yan)(yan)探測器還(huan)由監(jian)(jian)控攝像頭(tou)、底(di)盤和(he)冷凍設備組成。燃(ran)燒機火(huo)(huo)焰(yan)(yan)一次引燃(ran)區(qu)導致的(de)紅外(wai)輻射(she)依據光(guang)纖送至(zhi)監(jian)(jian)控攝像頭(tou)，由監(jian)(jian)控攝像頭(tou)內的(de)光(guang)刻工藝(yi)電(dian)(dian)阻轉換成電(dian)(dian)子器件數據信號(hao)(hao)，再經(jing)變(bian)大(da)(da)儀(yi)(yi)增大(da)(da)。火(huo)(huo)焰(yan)(yan)信號(hao)(hao)依據屏蔽雙(shuang)絞線發(fa)送到底(di)盤，經(jing)歷相頻特性電(dian)(dian)源總開關和(he)變(bian)大(da)(da)儀(yi)(yi)后(hou)，與參考工作(zuo)標(biao)準電(dian)(dian)壓(ya)（可調）進行比較。
