皮帶(dai)(dai)秤(cheng)是(shi)指無需(xu)對質量細(xi)分或者中斷(duan)輸送(song)(song)帶(dai)(dai)的運動，而對輸送(song)(song)帶(dai)(dai)上的散裝物料進行(xing)連續(xu)稱(cheng)(cheng)量的自動衡器，主要分類有按(an)承載(zai)器分類：稱(cheng)(cheng)量臺式承載(zai)器，輸送(song)(song)機式承載(zai)器；按(an)帶(dai)(dai)速分類：單(dan)速皮帶(dai)(dai)秤(cheng)，變(bian)速皮帶(dai)(dai)秤(cheng)。

　　電(dian)子皮(pi)帶(dai)(dai)秤稱重(zhong)(zhong)(zhong)橋架(jia)(jia)安(an)裝(zhuang)于(yu)輸送(song)機架(jia)(jia)上(shang)，當物料經(jing)過(guo)時，計量(liang)(liang)托輥檢測(ce)到皮(pi)帶(dai)(dai)機上(shang)的(de)(de)物料重(zhong)(zhong)(zhong)量(liang)(liang)通(tong)過(guo)杠桿作用于(yu)稱重(zhong)(zhong)(zhong)傳感器，產生一(yi)(yi)(yi)個正(zheng)(zheng)比(bi)于(yu)皮(pi)帶(dai)(dai)載荷的(de)(de)電(dian)壓信(xin)(xin)號(hao)(hao)。在(zai)皮(pi)帶(dai)(dai)秤上(shang)有一(yi)(yi)(yi)個稱重(zhong)(zhong)(zhong)傳感器裝(zhuang)在(zai)稱重(zhong)(zhong)(zhong)橋架(jia)(jia)上(shang)，工(gong)作時，將檢測(ce)到皮(pi)帶(dai)(dai)上(shang)的(de)(de)物料重(zhong)(zhong)(zhong)量(liang)(liang)送(song)入稱重(zhong)(zhong)(zhong)儀表(biao)(biao)，同時由測(ce)速傳感器皮(pi)帶(dai)(dai)輸送(song)機的(de)(de)速度(du)(du)信(xin)(xin)號(hao)(hao)也送(song)入稱重(zhong)(zhong)(zhong)儀表(biao)(biao)，儀表(biao)(biao)將速度(du)(du)信(xin)(xin)號(hao)(hao)與稱重(zhong)(zhong)(zhong)信(xin)(xin)號(hao)(hao)進行積(ji)分(fen)(fen)處理(li)，得到瞬(shun)時流量(liang)(liang)及累(lei)計量(liang)(liang)。速度(du)(du)傳感器直接連在(zai)大直徑測(ce)速滾筒上(shang)，提(ti)供一(yi)(yi)(yi)系(xi)列脈沖(chong)(chong)，每個脈沖(chong)(chong)表(biao)(biao)示一(yi)(yi)(yi)個皮(pi)帶(dai)(dai)運動(dong)單元，脈沖(chong)(chong)的(de)(de)頻率正(zheng)(zheng)比(bi)于(yu)皮(pi)帶(dai)(dai)速度(du)(du)。稱重(zhong)(zhong)(zhong)儀表(biao)(biao)從稱重(zhong)(zhong)(zhong)傳感器和速度(du)(du)傳感器接收信(xin)(xin)號(hao)(hao)，通(tong)過(guo)積(ji)分(fen)(fen)運算得出一(yi)(yi)(yi)個瞬(shun)時流量(liang)(liang)值(zhi)和累(lei)積(ji)重(zhong)(zhong)(zhong)量(liang)(liang)值(zhi)，并分(fen)(fen)別顯示出來。
