主要有機械(xie)式（常(chang)見的為(wei)滾(gun)輪皮帶秤）和電子式兩大類(lei)。后來出現了TTS型(xing)新型(xing)皮帶秤（三(san)技秤）。
電(dian)子(zi)皮(pi)帶秤承(cheng)重裝(zhuang)置的(de)秤架結構(gou)主要有雙(shuang)杠(gang)桿多托(tuo)輥(gun)式(shi)、單托(tuo)輥(gun)式(shi)、懸(xuan)臂式(shi)和懸(xuan)浮式(shi)4種(zhong)。雙(shuang)杠(gang)桿多托(tuo)輥(gun)式(shi)和懸(xuan)浮式(shi)秤架的(de)電(dian)子(zi)皮(pi)帶秤計量(liang)段(duan)較長(chang)，一般為2～8組托(tuo)輥(gun)，計量(liang)準確度高(gao)，適用于流量(liang)
較大、計(ji)量準確(que)度要求高(gao)的(de)(de)地(di)方(fang)(fang)。單托(tuo)輥式和(he)懸臂(bei)式秤(cheng)架的(de)(de)電子皮(pi)帶秤(cheng)的(de)(de)皮(pi)帶速度可由制造廠確(que)定(ding)，適用于流量較小(xiao)的(de)(de)地(di)方(fang)(fang)或控制流量配(pei)料用的(de)(de)地(di)方(fang)(fang)。
滾(gun)輪(lun)皮帶秤由(you)重力傳遞系統(tong)、滾(gun)輪(lun)、計(ji)數(shu)器和速(su)度(du)(du)(du)盤(pan)(pan)組成。速(su)度(du)(du)(du)盤(pan)(pan)轉速(su)正比于皮帶速(su)度(du)(du)(du)。滾(gun)輪(lun)滾(gun)動(dong)的(de)角速(su)度(du)(du)(du)正比于皮帶上通過的(de)物料(liao)(liao)(liao)量。滾(gun)輪(lun)在速(su)度(du)(du)(du)盤(pan)(pan)上滾(gun)動(dong)的(de)位置由(you)物料(liao)(liao)(liao)的(de)重力大(da)小來調整。當皮帶上沒有物料(liao)(liao)(liao)時(shi)，滾(gun)輪(lun)靠(kao)近速(su)度(du)(du)(du)盤(pan)(pan)，轉速(su)為零，計(ji)數(shu)器不(bu)累計(ji)；當皮帶上有物料(liao)(liao)(liao)時(shi)，滾(gun)輪(lun)隨著重力變大(da)向(xiang)周邊移動(dong)，并(bing)帶動(dong)計(ji)數(shu)器記下皮帶上通過的(de)物料(liao)(liao)(liao)總量。
電子皮帶(dai)秤
電(dian)子(zi)皮帶秤，由鋼制(zhi)機械秤架，測速傳感(gan)器，高(gao)精度測重傳感(gan)器，電(dian)子(zi)皮帶秤控制(zhi)顯(xian)示(shi)儀表(biao)等組成（圖(tu)2），能(neng)對(dui)固體物料進(jin)行(xing)連續(xu)動態(tai)計(ji)量。
稱(cheng)重(zhong)時(shi)，承重(zhong)裝(zhuang)置將(jiang)皮帶上(shang)物(wu)(wu)料的重(zhong)力傳(chuan)遞到(dao)稱(cheng)重(zhong)傳(chuan)感(gan)器上(shang)，稱(cheng)重(zhong)傳(chuan)感(gan)器即輸(shu)出正比于物(wu)(wu)料重(zhong)力的電壓（mV）信號，經(jing)放大器放大后送模/數(shu)轉換器變成數(shu)字量(liang)A，送到(dao)運(yun)算器；物(wu)(wu)料速度(du)(du)輸(shu)入速度(du)(du)傳(chuan)感(gan)器后，速度(du)(du)傳(chuan)感(gan)器即輸(shu)出脈(mo)沖數(shu)B，也送到(dao)運(yun)算器；運(yun)算器對A、B進行運(yun)算后，即這一測(ce)量(liang)周期的物(wu)(wu)料量(liang)。對每一測(ce)量(liang)周期進行累計(ji)，即可皮帶上(shang)連續(xu)通過的物(wu)(wu)料總量(liang)。
稱重(zhong)顯(xian)(xian)(xian)(xian)示(shi)(shi)(shi)(shi)(shi)器(qi)主(zhu)要有(you)(you)數(shu)字(zi)(zi)顯(xian)(xian)(xian)(xian)示(shi)(shi)(shi)(shi)(shi)和漢(han)字(zi)(zi)顯(xian)(xian)(xian)(xian)示(shi)(shi)(shi)(shi)(shi)兩(liang)種，漢(han)字(zi)(zi)顯(xian)(xian)(xian)(xian)示(shi)(shi)(shi)(shi)(shi)為數(shu)字(zi)(zi)顯(xian)(xian)(xian)(xian)示(shi)(shi)(shi)(shi)(shi)的升級(ji)產品(pin)。稱重(zhong)顯(xian)(xian)(xian)(xian)示(shi)(shi)(shi)(shi)(shi)器(qi)有(you)(you)累計和瞬時流量(liang)顯(xian)(xian)(xian)(xian)示(shi)(shi)(shi)(shi)(shi)，具(ju)有(you)(you)自動調(diao)零、半自動調(diao)零、自檢故障(zhang)、數(shu)字(zi)(zi)標定、流量(liang)控制、打(da)印等功(gong)能。漢(han)字(zi)(zi)顯(xian)(xian)(xian)(xian)示(shi)(shi)(shi)(shi)(shi)除(chu)此之(zhi)外還(huan)能顯(xian)(xian)(xian)(xian)示(shi)(shi)(shi)(shi)(shi)速度(du)。漢(han)字(zi)(zi)顯(xian)(xian)(xian)(xian)示(shi)(shi)(shi)(shi)(shi)在(zai)操(cao)作時有(you)(you)功(gong)能顯(xian)(xian)(xian)(xian)示(shi)(shi)(shi)(shi)(shi)，能更好的幫助使用人員操(cao)作。
