一般(ban)來說(shuo)，傳(chuan)(chuan)(chuan)感(gan)器(qi)(qi)的(de)(de)量(liang)程(cheng)越接近(jin)分配到(dao)每(mei)個傳(chuan)(chuan)(chuan)感(gan)器(qi)(qi)的(de)(de)載(zai)(zai)荷(he)，其稱量(liang)的(de)(de)準確(que)(que)度就越高。但(dan)在實習運用時(shi)，因(yin)為(wei)加在傳(chuan)(chuan)(chuan)感(gan)器(qi)(qi)上的(de)(de)載(zai)(zai)荷(he)除被稱物體外，還存在秤體自重(zhong)、皮重(zhong)、偏載(zai)(zai)及振動沖擊等載(zai)(zai)荷(he)，因(yin)此選用傳(chuan)(chuan)(chuan)感(gan)器(qi)(qi)量(liang)程(cheng)時(shi)，要考慮諸(zhu)多方(fang)面的(de)(de)要素，確(que)(que)保傳(chuan)(chuan)(chuan)感(gan)器(qi)(qi)的(de)(de)安全和(he)壽數。今天說(shuo)下(xia)稱重(zhong)傳(chuan)(chuan)(chuan)感(gan)器(qi)(qi)的(de)(de)數量(liang)和(he)量(liang)程(cheng)原理(li)：

  1、稱重傳感器的數量和量程

  一(yi)般(ban)應使稱(cheng)(cheng)重(zhong)(zhong)(zhong)傳(chuan)(chuan)感(gan)(gan)器(qi)(qi)(qi)在(zai)其30%～70%量程(cheng)內(nei)工作。但對于(yu)(yu)一(yi)些在(zai)運用(yong)過程(cheng)中存在(zai)較大(da)沖擊力的(de)衡(heng)器(qi)(qi)(qi)，如動(dong)態(tai)軌道(dao)衡(heng)、動(dong)態(tai)汽車(che)衡(heng)、鋼(gang)(gang)材(cai)秤(cheng)(cheng)(cheng)等(deng)，在(zai)選用(yong)稱(cheng)(cheng)重(zhong)(zhong)(zhong)傳(chuan)(chuan)感(gan)(gan)器(qi)(qi)(qi)時(shi)，一(yi)般(ban)要拓展其量程(cheng)，使稱(cheng)(cheng)重(zhong)(zhong)(zhong)傳(chuan)(chuan)感(gan)(gan)器(qi)(qi)(qi)在(zai)其量程(cheng)的(de)20%～30%以內(nei)工作，使稱(cheng)(cheng)重(zhong)(zhong)(zhong)傳(chuan)(chuan)感(gan)(gan)器(qi)(qi)(qi)的(de)稱(cheng)(cheng)量儲(chu)藏量程(cheng)增大(da)，以確保稱(cheng)(cheng)重(zhong)(zhong)(zhong)傳(chuan)(chuan)感(gan)(gan)器(qi)(qi)(qi)的(de)運用(yong)安全和壽數。稱(cheng)(cheng)重(zhong)(zhong)(zhong)傳(chuan)(chuan)感(gan)(gan)器(qi)(qi)(qi)型式(shi)(shi)(shi)的(de)選擇首(shou)要取(qu)決于(yu)(yu)稱(cheng)(cheng)量的(de)類型和設(she)備空(kong)間，確保設(she)備適宜，稱(cheng)(cheng)量安全可靠；另一(yi)方面(mian)，要考慮稱(cheng)(cheng)重(zhong)(zhong)(zhong)傳(chuan)(chuan)感(gan)(gan)器(qi)(qi)(qi)制造廠(chang)的(de)建議(yi)。制造廠(chang)一(yi)般(ban)會根據稱(cheng)(cheng)重(zhong)(zhong)(zhong)傳(chuan)(chuan)感(gan)(gan)器(qi)(qi)(qi)的(de)受力情況、功用(yong)政策、設(she)備方法、結構型式(shi)(shi)(shi)、彈性體的(de)資料(liao)等(deng)特(te)征(zheng)規矩稱(cheng)(cheng)重(zhong)(zhong)(zhong)傳(chuan)(chuan)感(gan)(gan)器(qi)(qi)(qi)的(de)適用(yong)計(ji)(ji)劃，比如鋁(lv)式(shi)(shi)(shi)懸臂梁(liang)稱(cheng)(cheng)重(zhong)(zhong)(zhong)傳(chuan)(chuan)感(gan)(gan)器(qi)(qi)(qi)適用(yong)于(yu)(yu)計(ji)(ji)價秤(cheng)(cheng)(cheng)、平臺秤(cheng)(cheng)(cheng)、案秤(cheng)(cheng)(cheng)等(deng)，鋼(gang)(gang)式(shi)(shi)(shi)懸臂梁(liang)稱(cheng)(cheng)重(zhong)(zhong)(zhong)傳(chuan)(chuan)感(gan)(gan)器(qi)(qi)(qi)適用(yong)于(yu)(yu)料(liao)斗秤(cheng)(cheng)(cheng)、電子皮帶(dai)秤(cheng)(cheng)(cheng)、分選秤(cheng)(cheng)(cheng)等(deng)，鋼(gang)(gang)質橋(qiao)式(shi)(shi)(shi)稱(cheng)(cheng)重(zhong)(zhong)(zhong)傳(chuan)(chuan)感(gan)(gan)器(qi)(qi)(qi)適用(yong)于(yu)(yu)軌道(dao)衡(heng)、汽車(che)衡(heng)、天(tian)車(che)秤(cheng)(cheng)(cheng)等(deng)，柱式(shi)(shi)(shi)稱(cheng)(cheng)重(zhong)(zhong)(zhong)傳(chuan)(chuan)感(gan)(gan)器(qi)(qi)(qi)適用(yong)于(yu)(yu)汽車(che)衡(heng)、動(dong)態(tai)軌道(dao)衡(heng)、大(da)噸位(wei)料(liao)斗秤(cheng)(cheng)(cheng)等(deng)。稱(cheng)(cheng)重(zhong)(zhong)(zhong)傳(chuan)(chuan)感(gan)(gan)器(qi)(qi)(qi)

  2、稱(cheng)重傳感(gan)器的準確度(du)等級選擇

  稱(cheng)重(zhong)傳(chuan)(chuan)感(gan)器(qi)的(de)(de)(de)準確度(du)等(deng)級包括稱(cheng)重(zhong)傳(chuan)(chuan)感(gan)器(qi)的(de)(de)(de)非線性(xing)(xing)、蠕變、重(zhong)復性(xing)(xing)、滯(zhi)后(hou)(hou)、靈敏(min)度(du)等(deng)技術政(zheng)策。在選用的(de)(de)(de)時分不(bu)應當(dang)盲目尋求高(gao)等(deng)級的(de)(de)(de)稱(cheng)重(zhong)傳(chuan)(chuan)感(gan)器(qi)，應當(dang)考慮電子衡(heng)的(de)(de)(de)準確度(du)等(deng)級和(he)本錢。一(yi)般情況下，選用稱(cheng)重(zhong)傳(chuan)(chuan)感(gan)器(qi)的(de)(de)(de)總精度(du)為非線性(xing)(xing)、不(bu)重(zhong)復性(xing)(xing)和(he)滯(zhi)后(hou)(hou)三項(xiang)政(zheng)策的(de)(de)(de)之和(he)的(de)(de)(de)均方根值略高(gao)于秤的(de)(de)(de)精度(du)。稱(cheng)重(zhong)傳(chuan)(chuan)感(gan)器(qi)

  3、各種類型稱重(zhong)傳感器的運用計劃

  選用(yong)的稱重(zhong)傳感(gan)(gan)器(qi)須滿足表(biao)面(mian)(mian)輸入靈敏度(du)的央(yang)(yang)求，須可以與(yu)所選表(biao)面(mian)(mian)匹(pi)配，滿足整臺電(dian)子(zi)(zi)秤準(zhun)(zhun)確度(du)的央(yang)(yang)求。一(yi)臺電(dian)子(zi)(zi)秤首要(yao)是由機(ji)械(xie)組織、稱重(zhong)傳感(gan)(gan)器(qi)、表(biao)面(mian)(mian)三(san)有些構成，在對稱重(zhong)傳感(gan)(gan)器(qi)準(zhun)(zhun)確度(du)選擇的時分(fen)，應使稱重(zhong)傳感(gan)(gan)器(qi)的準(zhun)(zhun)確度(du)略(lve)高于理論核(he)算值，因為理論一(yi)般遭(zao)到(dao)客觀條件的束縛，如機(ji)械(xie)結(jie)構的強(qiang)度(du)、表(biao)面(mian)(mian)的功用(yong)、秤的工作環境惡劣程度(du)等要(yao)素都(dou)直接(jie)影(ying)響到(dao)秤的準(zhun)(zhun)確度(du)。因此(ci)要(yao)從各方面(mian)(mian)行進央(yang)(yang)求，統籌經(jing)濟效益(yi)，確保(bao)抵達意(yi)圖(tu)。

  4、運用環境

  一般情況下(xia)，高溫(wen)環境(jing)對稱(cheng)重(zhong)(zhong)(zhong)傳(chuan)感器(qi)(qi)構成(cheng)涂覆資(zi)料(liao)融(rong)化(hua)、焊(han)點開(kai)化(hua)、彈性體(ti)(ti)內應(ying)力(li)發生結構改動(dong)等疑問；粉塵、濕潤對稱(cheng)重(zhong)(zhong)(zhong)傳(chuan)感器(qi)(qi)構成(cheng)短路(lu)的影響(xiang)；在腐蝕性較高的環境(jing)下(xia)會構成(cheng)稱(cheng)重(zhong)(zhong)(zhong)傳(chuan)感器(qi)(qi)彈性體(ti)(ti)受損或發生短路(lu)表象(xiang)；電(dian)磁場對稱(cheng)重(zhong)(zhong)(zhong)傳(chuan)感器(qi)(qi)輸(shu)出(chu)會發生攪擾。相(xiang)應(ying)的環境(jing)要(yao)(yao)素(su)下(xia)咱(zan)們(men)有必(bi)要(yao)(yao)選擇對應(ying)的稱(cheng)重(zhong)(zhong)(zhong)傳(chuan)感器(qi)(qi)才調滿足必(bi)要(yao)(yao)的稱(cheng)重(zhong)(zhong)(zhong)央(yang)求。

  通過(guo)對(dui)(dui)稱重(zhong)(zhong)傳感器(qi)的(de)數量(liang)和(he)量(liang)程原理的(de)了(le)(le)解，相信(xin)大家對(dui)(dui)稱重(zhong)(zhong)傳感器(qi)有了(le)(le)一定(ding)的(de)了(le)(le)解。
