皮帶秤是指無需對質量細分或者中斷輸送帶的運動，而對輸送帶上的散裝物料進行連續稱量的自動衡器，主要分類有按承載器分類：稱量台式承載器，輸送機式承載器；按帶速分類：單速皮帶秤，變速皮帶秤。

    電子皮帶秤稱cheng重zhong橋qiao架jia安an裝zhuang於yu輸shu送song機ji架jia上shang，當dang物wu料liao經jing過guo時shi，計ji量liang托tuo輥gun檢jian測ce到dao皮pi帶dai機ji上shang的de物wu料liao重zhong量liang通tong過guo杠gang杆gan作zuo用yong於yu稱cheng重zhong傳chuan感gan器qi，產chan生sheng一yi個ge正zheng比bi於yu皮pi帶dai載zai荷he的de電dian壓ya信xin號hao。在zai皮pi帶dai秤cheng上shang有you一yi個ge稱cheng重zhong傳chuan感gan器qi裝zhuang在zai稱cheng重zhong橋qiao架jia上shang
，工gong作zuo時shi，將jiang檢jian測ce到dao皮pi帶dai上shang的de物wu料liao重zhong量liang送song入ru稱cheng重zhong儀yi表biao，同tong時shi由you測ce速su傳chuan感gan器qi皮pi帶dai輸shu送song機ji的de速su度du信xin號hao也ye送song入ru稱cheng重zhong儀yi表biao，儀yi表biao將jiang速su度du信xin號hao與yu稱cheng重zhong信xin號hao進jin行xing積ji分fen處chu理li
，得de到dao瞬shun時shi流liu量liang及ji累lei計ji量liang。速su度du傳chuan感gan器qi直zhi接jie連lian在zai大da直zhi徑jing測ce速su滾gun筒tong上shang
