LBT-50s管道在線粉塵濃度監測儀工作原理:
當(dang)帶電(dian)(dian)(dian)(dian)(dian)粉塵顆粒通(tong)過(guo)測(ce)(ce)狼電(dian)(dian)(dian)(dian)(dian)極(ji)時,測(ce)(ce)量(liang)電(dian)(dian)(dian)(dian)(dian)極(ji)感應出正(zheng)負電(dian)(dian)(dian)(dian)(dian)荷,電(dian)(dian)(dian)(dian)(dian)荷在(zai)轉移(yi)運動中形(xing)成電(dian)(dian)(dian)(dian)(dian)流信號(hao);此(ci)交流電(dian)(dian)(dian)(dian)(dian)信號(hao)的(de)大小和粉塵質量(liang)含(han)量(liang)成正(zheng)比。通(tong)過(guo)對此(ci)電(dian)(dian)(dian)(dian)(dian)信號(hao)進一步(bu)放大、運算處理,從(cong)而(er)測(ce)(ce)量(liang)出粉塵濃(nong)度mg/Nm3智能(neng)電(dian)(dian)(dian)(dian)(dian)路(lu)設計,有三路(lu)報警,可(ke)任意設計。廣泛應用于冶金、發電(dian)(dian)(dian)(dian)(dian)、水泥等行業氣固兩相(xiang)流的(de)含(han)塵量(liang)在(zai)線測(ce)(ce)量(liang),主要(yao)使用場所:TRT發電(dian)(dian)(dian)(dian)(dian),濕(shi)法除(chu)(chu)塵,除(chu)(chu)塵總(zong)管,電(dian)(dian)(dian)(dian)(dian)除(chu)(chu)塵或(huo)其他除(chu)(chu)塵場所。
