       2.檢測液化氣(qi)等(deng)(deng)比空氣(qi)重的可(ke)燃氣(qi)體(ti)時(shi)，其安裝高度應(ying)(ying)距地(di)(di)面（或地(di)(di)板(ban)）0.3m~0.6m，且(qie)應(ying)(ying)在(zai)同一高度級別作為發布源(yuan)。距離應(ying)(ying)小于 4m。此外，還要注意雨(yu)水(shui)、濺(jian)水(shui)等(deng)(deng)外部環(huan)境因素對探(tan)測器(qi)造成的損壞。建議(yi)為探(tan)測器(qi)配備防(fang)雨(yu)罩(zhao)。

       3.檢測氨等比重(zhong)小于(yu)空氣(qi)的(de)(de)有(you)(you)毒有(you)(you)害氣(qi)體(ti)時，除安裝(zhuang)在高于(yu)釋放(fang)(fang)源(yuan)0.5m~2m的(de)(de)位置外，還應安裝(zhuang)在車(che)間的(de)(de)高點容易積氣(qi)。與(yu)釋放(fang)(fang)源(yuan)的(de)(de)水平(ping)距離小于(yu)1m。

       4.檢測(ce)硫化氫等(deng)比(bi)重大于(yu)空(kong)氣的有(you)毒有(you)害氣體時，安裝在距離地(di)面0.3m~0.6m處(chu)，并與(yu)釋放源的水平距離應小于(yu) 1m。 

       5.檢測一(yi)氧化碳等與(yu)空(kong)氣(qi)(qi)比重接近、易與(yu)空(kong)氣(qi)(qi)混合(he)的有毒(du)氣(qi)(qi)體(ti)(ti)，應(ying)(ying)安裝(zhuang)在(zai)釋(shi)放(fang)源上下(xia)1m以內。當有毒(du)氣(qi)(qi)體(ti)(ti)比空(kong)氣(qi)(qi)略輕時，應(ying)(ying)安裝(zhuang)在(zai)釋(shi)放(fang)源上方。當有毒(du)氣(qi)(qi)體(ti)(ti)略重于空(kong)氣(qi)(qi)時，應(ying)(ying)安裝(zhuang)在(zai)釋(shi)放(fang)源下(xia)方，與(yu)釋(shi)放(fang)源的水平距離不(bu)宜過1m。

    &nbsp;  6.探測器應安裝在(zai)無沖擊、無振動、無強電磁(ci)場(chang)干擾、周(zhou)圍(wei)凈空<0.3m的地方。

       7.儀表(biao)的(de)安裝(zhuang)、接線除(chu)應符合(he)制造(zao)廠規定的(de)要求外，還應符合(he)GB50058-2014《爆炸性危險環境電(dian)氣裝(zhuang)置設計規范》的(de)相(xiang)關規定。 

       8.選擇安(an)裝位置時還應注意以下幾點

       （1)目標氣體在空氣中的擴散速(su)度(du)（與氣體本身、空氣密(mi)度(du)、風(feng)向(xiang)和(he)風(feng)速(su)等有關）。

       （2)通風也是必須考(kao)慮的(de)一(yi)(yi)個因素。空(kong)氣的(de)流動(dong)會導(dao)致目(mu)標(biao)氣體(ti)(ti)在(zai)一(yi)(yi)處比另一(yi)(yi)處積(ji)累更多。探測器(qi)應安裝(zhuang)在(zai)目(mu)標(biao)氣體(ti)(ti)容易積(ji)聚的(de)地(di)方(fang)(fang). 閥門、管(guan)接頭、出(chu)風口(kou)等易漏水(shui)的(de)地(di)方(fang)(fang)，半徑1m以內，盡(jin)量靠近；但不影響其他設備運行(xing)，盡(jin)量避免高溫(wen)高濕環境，避免外接影響，如(ru)飛(fei)濺的(de)水(shui)、油和其他機械(xie)損壞的(de)可能性。同時，應考(kao)慮維護和校準的(de)方(fang)(fang)便性。 

       （3)探測(ce)器安裝在室外時(shi)，建議加(jia)防雨(yu)罩，避免雨(yu)雪等對探測(ce)器的影響。
