style="text-indent:25px">工作原理：由于驅(qū)動(dòng)紅外發(fā)射管的是振蕩電路，很小的占空比使得流過紅外發(fā)射管的平均電流也很小。當(dāng)一定濃度的煙霧進(jìn)入煙室時(shí)，間歇發(fā)射的紅外線經(jīng)過煙霧顆粒的漫反射照射到紅外接收管，被紅外接收管轉(zhuǎn)換成光電流后又被三極管VT1放大，如果出現(xiàn)集成電路8腳電壓瞬間低手1／2Vco，9腳就會反轉(zhuǎn)為高電平，報(bào)警電路立即發(fā)出報(bào)警聲，直至煙霧消失后再延續(xù)一段時(shí)間才能恢復(fù)正常。MQ-2煙霧傳感器有6個(gè)引腳，寧波氬氣報(bào)警器哪家好，其中中間的2個(gè)為電阻絲，剩下的4個(gè)引腳分別為2個(gè)輸入引腳和兩個(gè)輸出引腳。其中中間的兩個(gè)引腳為信號輸出端，其輸出為模擬電壓量，范圍為0～1V，寧波氬氣報(bào)警器哪家好，寧波氬氣報(bào)警器哪家好。報(bào)警器不可以安裝在排氣扇、門浴室這類地方，這種高靈敏的儀器對水沒有抵抗能力。寧波氬氣報(bào)警器哪家好</p><div

style="text-indent:25px">離子式煙感探測器的工作原理是電離室內(nèi)的放射源媚Am241，電離產(chǎn)生的正、負(fù)離子，在電場作用下，各向正負(fù)電極移動(dòng)。正常情況下，內(nèi)外電離室的電流、電壓都是穩(wěn)定的，但當(dāng)火災(zāi)發(fā)生時(shí)，有煙霧竄進(jìn)外電離室，干擾帶電粒子正常運(yùn)行時(shí)，則會使電流、電壓有所改變，破壞內(nèi)外電離室之間的平衡，在檢測電離室兩端的電壓增加量達(dá)到一定值時(shí)，探測器就會對此產(chǎn)生感應(yīng)，開關(guān)電路動(dòng)作則將報(bào)警信息傳遞出去。當(dāng)物質(zhì)燃燒的時(shí)候，往往會先產(chǎn)生煙霧，接著產(chǎn)生可見與不可見光，而物質(zhì)由開始燃燒到火勢逐漸變大時(shí)總有個(gè)過程，煙感探測器則會“捕捉”到物質(zhì)燃燒時(shí)的“信號”，并把“捕捉”到的“信號”轉(zhuǎn)變成電信號，傳輸給火災(zāi)自動(dòng)報(bào)警系統(tǒng)的控制器。寧波氬氣報(bào)警器哪家好報(bào)警器對于有試驗(yàn)按鈕的儀器，啟動(dòng)報(bào)警器的試驗(yàn)按鈕，即可檢查報(bào)警器的報(bào)警功能是否正常。</p><div
