淺聊稱重傳感器的工作原理

稱(cheng)(cheng)重(zhong)(zhong)(zhong)(zhong)傳(chuan)感(gan)(gan)器：被稱(cheng)(cheng)重(zhong)(zhong)(zhong)(zhong)物或(huo)載重(zhong)(zhong)(zhong)(zhong)汽(qi)車(che)置于承載器臺面上，在重(zhong)(zhong)(zhong)(zhong)力作用(yong)下，通(tong)過承載器將重(zhong)(zhong)(zhong)(zhong)力傳(chuan)遞至稱(cheng)(cheng)重(zhong)(zhong)(zhong)(zhong)傳(chuan)感(gan)(gan)器，使稱(cheng)(cheng)重(zhong)(zhong)(zhong)(zhong)傳(chuan)感(gan)(gan)器彈性(xing)體產生變形，貼附于彈性(xing)體上的(de)應變計(ji)橋路(lu)失去平衡，輸出(chu)與重(zhong)(zhong)(zhong)(zhong)量(liang)(liang)數(shu)值成正(zheng)比例的(de)電信號，經線性(xing)放(fang)(fang)大(da)器將信號放(fang)(fang)大(da)。再(zai)經A/D轉(zhuan)換為數(shu)字信號，由(you)儀表的(de)微處理(li)(li)機(ji)(ji)（CPU）對(dui)重(zhong)(zhong)(zhong)(zhong)量(liang)(liang)信號進行處理(li)(li)后直接(jie)顯示重(zhong)(zhong)(zhong)(zhong)量(liang)(liang)數(shu)據(ju)。配置打(da)印機(ji)(ji)后，即可打(da)印記錄稱(cheng)(cheng)重(zhong)(zhong)(zhong)(zhong)數(shu)據(ju)，如果配置計(ji)算機(ji)(ji)可將計(ji)量(liang)(liang)數(shu)據(ju)輸入計(ji)算機(ji)(ji)管(guan)理(li)(li)系統進行綜(zong)合管(guan)理(li)(li)。
         在稱重(zhong)傳感器的(de)彈(dan)性(xing)體上粘貼(tie)有應(ying)變(bian)計，組成惠斯登電橋(qiao)。在無負荷(he)時(shi)，電橋(qiao)處于平(ping)衡狀態(tai)，輸出為零(ling)。當彈(dan)性(xing)體承受載(zai)荷(he)時(shi)，各(ge)應(ying)變(bian)計隨之產(chan)生與(yu)(yu)載(zai)荷(he)成比(bi)例的(de)應(ying)變(bian)，由輸出電壓即(ji)可(ke)測出外載(zai)重(zhong)量，通(tong)過儀表的(de)通(tong)訊接口可(ke)以(yi)與(yu)(yu)上位機連接。
