皮帶(dai)(dai)秤是指無需(xu)對質量(liang)細分或者中(zhong)斷輸(shu)送帶(dai)(dai)的(de)運動，而對輸(shu)送帶(dai)(dai)上的(de)散裝物料進(jin)行連(lian)續稱量(liang)的(de)自動衡器，主要分類(lei)有按(an)承(cheng)(cheng)載器分類(lei)：稱量(liang)臺式(shi)承(cheng)(cheng)載器，輸(shu)送機式(shi)承(cheng)(cheng)載器；按(an)帶(dai)(dai)速(su)分類(lei)：單(dan)速(su)皮帶(dai)(dai)秤，變速(su)皮帶(dai)(dai)秤。

　　電子皮帶秤

　　電(dian)子皮(pi)帶秤，由鋼制機械秤架，測(ce)速傳感器，高(gao)精(jing)度測(ce)重(zhong)傳感器，電(dian)子皮(pi)帶秤控制顯(xian)示儀表等(deng)組成，能對固(gu)體物料進行連(lian)續動(dong)態計量。

　　稱重(zhong)(zhong)時，承(cheng)重(zhong)(zhong)裝(zhuang)置將(jiang)皮帶上物料的重(zhong)(zhong)力傳(chuan)遞到(dao)稱重(zhong)(zhong)傳(chuan)感器(qi)(qi)(qi)(qi)上，稱重(zhong)(zhong)傳(chuan)感器(qi)(qi)(qi)(qi)即輸出正比于物料重(zhong)(zhong)力的電壓（mV）信號，經放大器(qi)(qi)(qi)(qi)放大后(hou)送模/數轉換器(qi)(qi)(qi)(qi)變成數字量A，送到(dao)運(yun)算器(qi)(qi)(qi)(qi)；物料速(su)(su)(su)度(du)輸入速(su)(su)(su)度(du)傳(chuan)感器(qi)(qi)(qi)(qi)后(hou)，速(su)(su)(su)度(du)傳(chuan)感器(qi)(qi)(qi)(qi)即輸出脈沖數B，也送到(dao)運(yun)算器(qi)(qi)(qi)(qi)；運(yun)算器(qi)(qi)(qi)(qi)對A、B進(jin)行(xing)運(yun)算后(hou)，即得到(dao)這(zhe)一測(ce)量周期的物料量。對每一測(ce)量周期進(jin)行(xing)累(lei)計，即可得到(dao)皮帶上連續通過的物料總量。

　　稱(cheng)重(zhong)顯(xian)(xian)示器(qi)主要有(you)數(shu)字顯(xian)(xian)示和(he)漢字顯(xian)(xian)示兩(liang)種(zhong)，漢字顯(xian)(xian)示為(wei)數(shu)字顯(xian)(xian)示的升級產品。稱(cheng)重(zhong)顯(xian)(xian)示器(qi)有(you)累計和(he)瞬時流量顯(xian)(xian)示，具有(you)自(zi)(zi)動調零、半自(zi)(zi)動調零、自(zi)(zi)檢故障、數(shu)字標定、流量控制(zhi)、打(da)印等功(gong)能(neng)。漢字顯(xian)(xian)示除(chu)此(ci)之(zhi)外還(huan)能(neng)顯(xian)(xian)示速度。漢字顯(xian)(xian)示在操作時有(you)功(gong)能(neng)顯(xian)(xian)示，能(neng)更好的幫助使(shi)用人(ren)員操作。
