一般(ban)來說(shuo)，傳(chuan)感器(qi)(qi)的(de)量(liang)程(cheng)(cheng)越接近分配到每(mei)個傳(chuan)感器(qi)(qi)的(de)載(zai)(zai)荷，其稱(cheng)量(liang)的(de)準確度就(jiu)越高。但在(zai)實(shi)習運(yun)用時，因(yin)為加(jia)在(zai)傳(chuan)感器(qi)(qi)上的(de)載(zai)(zai)荷除被稱(cheng)物(wu)體外，還存在(zai)秤體自(zi)重、皮重、偏載(zai)(zai)及振動沖擊等載(zai)(zai)荷，因(yin)此(ci)選用傳(chuan)感器(qi)(qi)量(liang)程(cheng)(cheng)時，要(yao)考慮(lv)諸(zhu)多方面(mian)的(de)要(yao)素，確保(bao)傳(chuan)感器(qi)(qi)的(de)安(an)全和(he)壽數。今天說(shuo)下稱(cheng)重傳(chuan)感器(qi)(qi)的(de)數量(liang)和(he)量(liang)程(cheng)(cheng)原理：

  1、稱(cheng)重傳(chuan)感器的數(shu)量和量程(cheng)

  一(yi)般應使稱(cheng)(cheng)重(zhong)(zhong)(zhong)(zhong)傳(chuan)(chuan)(chuan)(chuan)感(gan)(gan)器(qi)(qi)(qi)在(zai)其30%～70%量(liang)程(cheng)內工(gong)作(zuo)(zuo)。但對于一(yi)些(xie)在(zai)運用(yong)(yong)過(guo)程(cheng)中(zhong)存在(zai)較大沖擊(ji)力的(de)(de)(de)(de)衡(heng)(heng)器(qi)(qi)(qi)，如(ru)動(dong)態(tai)軌道衡(heng)(heng)、動(dong)態(tai)汽(qi)車(che)衡(heng)(heng)、鋼材秤(cheng)等(deng)(deng)，在(zai)選用(yong)(yong)稱(cheng)(cheng)重(zhong)(zhong)(zhong)(zhong)傳(chuan)(chuan)(chuan)(chuan)感(gan)(gan)器(qi)(qi)(qi)時，一(yi)般要拓展其量(liang)程(cheng)，使稱(cheng)(cheng)重(zhong)(zhong)(zhong)(zhong)傳(chuan)(chuan)(chuan)(chuan)感(gan)(gan)器(qi)(qi)(qi)在(zai)其量(liang)程(cheng)的(de)(de)(de)(de)20%～30%以(yi)內工(gong)作(zuo)(zuo)，使稱(cheng)(cheng)重(zhong)(zhong)(zhong)(zhong)傳(chuan)(chuan)(chuan)(chuan)感(gan)(gan)器(qi)(qi)(qi)的(de)(de)(de)(de)稱(cheng)(cheng)量(liang)儲藏量(liang)程(cheng)增(zeng)大，以(yi)確保稱(cheng)(cheng)重(zhong)(zhong)(zhong)(zhong)傳(chuan)(chuan)(chuan)(chuan)感(gan)(gan)器(qi)(qi)(qi)的(de)(de)(de)(de)運用(yong)(yong)安全和壽(shou)數。稱(cheng)(cheng)重(zhong)(zhong)(zhong)(zhong)傳(chuan)(chuan)(chuan)(chuan)感(gan)(gan)器(qi)(qi)(qi)型式(shi)的(de)(de)(de)(de)選擇首要取決于稱(cheng)(cheng)量(liang)的(de)(de)(de)(de)類型和設備(bei)空間，確保設備(bei)適(shi)宜，稱(cheng)(cheng)量(liang)安全可靠；另(ling)一(yi)方面，要考慮(lv)稱(cheng)(cheng)重(zhong)(zhong)(zhong)(zhong)傳(chuan)(chuan)(chuan)(chuan)感(gan)(gan)器(qi)(qi)(qi)制造廠的(de)(de)(de)(de)建議(yi)。制造廠一(yi)般會根(gen)據(ju)稱(cheng)(cheng)重(zhong)(zhong)(zhong)(zhong)傳(chuan)(chuan)(chuan)(chuan)感(gan)(gan)器(qi)(qi)(qi)的(de)(de)(de)(de)受力情(qing)況、功用(yong)(yong)政策、設備(bei)方法、結構型式(shi)、彈性體(ti)的(de)(de)(de)(de)資(zi)料等(deng)(deng)特征規矩稱(cheng)(cheng)重(zhong)(zhong)(zhong)(zhong)傳(chuan)(chuan)(chuan)(chuan)感(gan)(gan)器(qi)(qi)(qi)的(de)(de)(de)(de)適(shi)用(yong)(yong)計(ji)劃，比(bi)如(ru)鋁(lv)式(shi)懸(xuan)臂梁(liang)稱(cheng)(cheng)重(zhong)(zhong)(zhong)(zhong)傳(chuan)(chuan)(chuan)(chuan)感(gan)(gan)器(qi)(qi)(qi)適(shi)用(yong)(yong)于計(ji)價秤(cheng)、平臺秤(cheng)、案(an)秤(cheng)等(deng)(deng)，鋼式(shi)懸(xuan)臂梁(liang)稱(cheng)(cheng)重(zhong)(zhong)(zhong)(zhong)傳(chuan)(chuan)(chuan)(chuan)感(gan)(gan)器(qi)(qi)(qi)適(shi)用(yong)(yong)于料斗秤(cheng)、電(dian)子皮(pi)帶秤(cheng)、分選秤(cheng)等(deng)(deng)，鋼質橋式(shi)稱(cheng)(cheng)重(zhong)(zhong)(zhong)(zhong)傳(chuan)(chuan)(chuan)(chuan)感(gan)(gan)器(qi)(qi)(qi)適(shi)用(yong)(yong)于軌道衡(heng)(heng)、汽(qi)車(che)衡(heng)(heng)、天(tian)車(che)秤(cheng)等(deng)(deng)，柱式(shi)稱(cheng)(cheng)重(zhong)(zhong)(zhong)(zhong)傳(chuan)(chuan)(chuan)(chuan)感(gan)(gan)器(qi)(qi)(qi)適(shi)用(yong)(yong)于汽(qi)車(che)衡(heng)(heng)、動(dong)態(tai)軌道衡(heng)(heng)、大噸(dun)位料斗秤(cheng)等(deng)(deng)。稱(cheng)(cheng)重(zhong)(zhong)(zhong)(zhong)傳(chuan)(chuan)(chuan)(chuan)感(gan)(gan)器(qi)(qi)(qi)

  2、稱重(zhong)傳感器的準確度等級選擇

  稱(cheng)(cheng)重傳感(gan)器(qi)的準確度等(deng)級(ji)包括(kuo)稱(cheng)(cheng)重傳感(gan)器(qi)的非線(xian)性(xing)(xing)(xing)、蠕(ru)變、重復性(xing)(xing)(xing)、滯后(hou)、靈敏度等(deng)技術政(zheng)策。在選用的時(shi)分(fen)不(bu)應(ying)當(dang)盲目尋求高(gao)等(deng)級(ji)的稱(cheng)(cheng)重傳感(gan)器(qi)，應(ying)當(dang)考慮電子(zi)衡的準確度等(deng)級(ji)和本錢。一般情況(kuang)下，選用稱(cheng)(cheng)重傳感(gan)器(qi)的總(zong)精(jing)(jing)度為(wei)非線(xian)性(xing)(xing)(xing)、不(bu)重復性(xing)(xing)(xing)和滯后(hou)三項(xiang)政(zheng)策的之和的均方根值略高(gao)于秤的精(jing)(jing)度。稱(cheng)(cheng)重傳感(gan)器(qi)

  3、各(ge)種類型稱(cheng)重傳感器的運用計劃

  選用(yong)的(de)(de)稱(cheng)重(zhong)傳(chuan)感器(qi)(qi)須(xu)滿足表(biao)面(mian)(mian)輸入(ru)靈敏度(du)的(de)(de)央求，須(xu)可以與所選表(biao)面(mian)(mian)匹配，滿足整(zheng)臺電(dian)子(zi)秤準(zhun)(zhun)確(que)度(du)的(de)(de)央求。一臺電(dian)子(zi)秤首要(yao)是由機械(xie)組織、稱(cheng)重(zhong)傳(chuan)感器(qi)(qi)、表(biao)面(mian)(mian)三有些構成，在對(dui)稱(cheng)重(zhong)傳(chuan)感器(qi)(qi)準(zhun)(zhun)確(que)度(du)選擇的(de)(de)時分(fen)，應(ying)使稱(cheng)重(zhong)傳(chuan)感器(qi)(qi)的(de)(de)準(zhun)(zhun)確(que)度(du)略高于理(li)論核算值，因為(wei)理(li)論一般遭到客觀條件的(de)(de)束縛，如機械(xie)結構的(de)(de)強度(du)、表(biao)面(mian)(mian)的(de)(de)功用(yong)、秤的(de)(de)工作環境惡劣(lie)程度(du)等要(yao)素都直接(jie)影響到秤的(de)(de)準(zhun)(zhun)確(que)度(du)。因此要(yao)從各(ge)方面(mian)(mian)行進(jin)央求，統籌(chou)經濟效益，確(que)保抵達意圖(tu)。

  4、運用環(huan)境

  一般情(qing)況下，高溫(wen)環(huan)境對(dui)(dui)(dui)稱(cheng)重(zhong)(zhong)(zhong)(zhong)傳感器(qi)(qi)構(gou)(gou)(gou)成涂覆資(zi)料融化(hua)、焊點(dian)開化(hua)、彈性(xing)體內應力發(fa)生(sheng)結(jie)構(gou)(gou)(gou)改(gai)動(dong)等疑問；粉(fen)塵、濕潤對(dui)(dui)(dui)稱(cheng)重(zhong)(zhong)(zhong)(zhong)傳感器(qi)(qi)構(gou)(gou)(gou)成短路(lu)的(de)(de)影響；在腐蝕性(xing)較高的(de)(de)環(huan)境下會構(gou)(gou)(gou)成稱(cheng)重(zhong)(zhong)(zhong)(zhong)傳感器(qi)(qi)彈性(xing)體受損或發(fa)生(sheng)短路(lu)表(biao)象；電磁場對(dui)(dui)(dui)稱(cheng)重(zhong)(zhong)(zhong)(zhong)傳感器(qi)(qi)輸(shu)出會發(fa)生(sheng)攪擾。相應的(de)(de)環(huan)境要(yao)素(su)下咱(zan)們有必要(yao)選擇對(dui)(dui)(dui)應的(de)(de)稱(cheng)重(zhong)(zhong)(zhong)(zhong)傳感器(qi)(qi)才(cai)調滿(man)足必要(yao)的(de)(de)稱(cheng)重(zhong)(zhong)(zhong)(zhong)央求。

  通過對稱(cheng)重傳感器的(de)數量和量程原(yuan)理(li)的(de)了解，相信(xin)大家對稱(cheng)重傳感器有(you)了一定的(de)了解。
