一般來說(shuo)，傳(chuan)感(gan)器(qi)的(de)(de)量(liang)(liang)程(cheng)越接(jie)近分配到每個傳(chuan)感(gan)器(qi)的(de)(de)載荷(he)，其稱量(liang)(liang)的(de)(de)準確(que)度就(jiu)越高。但在實習(xi)運用時，因為加在傳(chuan)感(gan)器(qi)上(shang)的(de)(de)載荷(he)除(chu)被稱物體(ti)外，還存在秤體(ti)自重(zhong)、皮重(zhong)、偏(pian)載及振動沖擊等載荷(he)，因此選(xuan)用傳(chuan)感(gan)器(qi)量(liang)(liang)程(cheng)時，要(yao)考慮諸多方面的(de)(de)要(yao)素，確(que)保(bao)傳(chuan)感(gan)器(qi)的(de)(de)安全和(he)(he)壽數。今天(tian)說(shuo)下(xia)稱重(zhong)傳(chuan)感(gan)器(qi)的(de)(de)數量(liang)(liang)和(he)(he)量(liang)(liang)程(cheng)原理：

  1、稱(cheng)重傳感(gan)器的數量和量程

  一(yi)(yi)般應使稱(cheng)(cheng)重(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)傳(chuan)(chuan)(chuan)感(gan)(gan)器(qi)(qi)在其30%～70%量(liang)(liang)程(cheng)內(nei)工作。但對(dui)于一(yi)(yi)些在運用(yong)(yong)過(guo)程(cheng)中存在較大(da)沖擊力(li)的(de)(de)衡(heng)器(qi)(qi)，如(ru)(ru)動態軌(gui)道(dao)衡(heng)、動態汽(qi)車衡(heng)、鋼(gang)(gang)材秤(cheng)等，在選用(yong)(yong)稱(cheng)(cheng)重(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)傳(chuan)(chuan)(chuan)感(gan)(gan)器(qi)(qi)時，一(yi)(yi)般要(yao)(yao)拓(tuo)展其量(liang)(liang)程(cheng)，使稱(cheng)(cheng)重(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)傳(chuan)(chuan)(chuan)感(gan)(gan)器(qi)(qi)在其量(liang)(liang)程(cheng)的(de)(de)20%～30%以內(nei)工作，使稱(cheng)(cheng)重(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)傳(chuan)(chuan)(chuan)感(gan)(gan)器(qi)(qi)的(de)(de)稱(cheng)(cheng)量(liang)(liang)儲藏量(liang)(liang)程(cheng)增大(da)，以確(que)保稱(cheng)(cheng)重(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)傳(chuan)(chuan)(chuan)感(gan)(gan)器(qi)(qi)的(de)(de)運用(yong)(yong)安全和壽數。稱(cheng)(cheng)重(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)傳(chuan)(chuan)(chuan)感(gan)(gan)器(qi)(qi)型式(shi)的(de)(de)選擇(ze)首要(yao)(yao)取決于稱(cheng)(cheng)量(liang)(liang)的(de)(de)類(lei)型和設(she)(she)備(bei)(bei)空間，確(que)保設(she)(she)備(bei)(bei)適(shi)(shi)宜，稱(cheng)(cheng)量(liang)(liang)安全可靠；另一(yi)(yi)方(fang)面，要(yao)(yao)考慮稱(cheng)(cheng)重(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)傳(chuan)(chuan)(chuan)感(gan)(gan)器(qi)(qi)制造(zao)廠的(de)(de)建議。制造(zao)廠一(yi)(yi)般會根據稱(cheng)(cheng)重(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)傳(chuan)(chuan)(chuan)感(gan)(gan)器(qi)(qi)的(de)(de)受(shou)力(li)情況(kuang)、功(gong)用(yong)(yong)政策、設(she)(she)備(bei)(bei)方(fang)法、結構(gou)型式(shi)、彈性體(ti)的(de)(de)資料等特征規矩(ju)稱(cheng)(cheng)重(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)傳(chuan)(chuan)(chuan)感(gan)(gan)器(qi)(qi)的(de)(de)適(shi)(shi)用(yong)(yong)計劃，比如(ru)(ru)鋁式(shi)懸臂梁稱(cheng)(cheng)重(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)傳(chuan)(chuan)(chuan)感(gan)(gan)器(qi)(qi)適(shi)(shi)用(yong)(yong)于計價秤(cheng)、平(ping)臺秤(cheng)、案秤(cheng)等，鋼(gang)(gang)式(shi)懸臂梁稱(cheng)(cheng)重(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)傳(chuan)(chuan)(chuan)感(gan)(gan)器(qi)(qi)適(shi)(shi)用(yong)(yong)于料斗(dou)秤(cheng)、電子皮帶秤(cheng)、分(fen)選秤(cheng)等，鋼(gang)(gang)質橋(qiao)式(shi)稱(cheng)(cheng)重(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)傳(chuan)(chuan)(chuan)感(gan)(gan)器(qi)(qi)適(shi)(shi)用(yong)(yong)于軌(gui)道(dao)衡(heng)、汽(qi)車衡(heng)、天(tian)車秤(cheng)等，柱式(shi)稱(cheng)(cheng)重(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)傳(chuan)(chuan)(chuan)感(gan)(gan)器(qi)(qi)適(shi)(shi)用(yong)(yong)于汽(qi)車衡(heng)、動態軌(gui)道(dao)衡(heng)、大(da)噸位料斗(dou)秤(cheng)等。稱(cheng)(cheng)重(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)傳(chuan)(chuan)(chuan)感(gan)(gan)器(qi)(qi)

  2、稱重傳感器的準(zhun)確(que)度等級選擇

  稱重(zhong)(zhong)(zhong)傳(chuan)(chuan)感(gan)(gan)器(qi)的(de)(de)(de)(de)準(zhun)確度(du)等級包(bao)括(kuo)稱重(zhong)(zhong)(zhong)傳(chuan)(chuan)感(gan)(gan)器(qi)的(de)(de)(de)(de)非(fei)線(xian)性、蠕變、重(zhong)(zhong)(zhong)復性、滯后、靈敏度(du)等技術政(zheng)策。在選用(yong)的(de)(de)(de)(de)時分(fen)不(bu)應當盲目尋求高等級的(de)(de)(de)(de)稱重(zhong)(zhong)(zhong)傳(chuan)(chuan)感(gan)(gan)器(qi)，應當考慮電(dian)子衡的(de)(de)(de)(de)準(zhun)確度(du)等級和本錢。一般情況下，選用(yong)稱重(zhong)(zhong)(zhong)傳(chuan)(chuan)感(gan)(gan)器(qi)的(de)(de)(de)(de)總(zong)精度(du)為非(fei)線(xian)性、不(bu)重(zhong)(zhong)(zhong)復性和滯后三(san)項政(zheng)策的(de)(de)(de)(de)之和的(de)(de)(de)(de)均方根值(zhi)略(lve)高于秤的(de)(de)(de)(de)精度(du)。稱重(zhong)(zhong)(zhong)傳(chuan)(chuan)感(gan)(gan)器(qi)

  3、各種類型稱重傳感器的運用(yong)計劃

  選(xuan)(xuan)用的稱重(zhong)傳感(gan)(gan)器須(xu)滿足(zu)表面(mian)輸入靈敏(min)度(du)(du)(du)的央求，須(xu)可以與(yu)所選(xuan)(xuan)表面(mian)匹(pi)配(pei)，滿足(zu)整臺(tai)電子秤(cheng)準確(que)度(du)(du)(du)的央求。一臺(tai)電子秤(cheng)首(shou)要(yao)是由機械(xie)組織(zhi)、稱重(zhong)傳感(gan)(gan)器、表面(mian)三有些構(gou)成，在(zai)對稱重(zhong)傳感(gan)(gan)器準確(que)度(du)(du)(du)選(xuan)(xuan)擇(ze)的時分，應使稱重(zhong)傳感(gan)(gan)器的準確(que)度(du)(du)(du)略高(gao)于理(li)論(lun)核算值(zhi)，因為理(li)論(lun)一般遭到(dao)客觀條件(jian)的束縛，如機械(xie)結構(gou)的強度(du)(du)(du)、表面(mian)的功(gong)用、秤(cheng)的工作環境惡劣程度(du)(du)(du)等(deng)要(yao)素都直接影(ying)響到(dao)秤(cheng)的準確(que)度(du)(du)(du)。因此要(yao)從各(ge)方面(mian)行進央求，統籌經(jing)濟效益，確(que)保抵達(da)意圖。

  4、運用環境

  一般情況下(xia)，高溫(wen)環(huan)境對(dui)稱(cheng)重(zhong)傳(chuan)(chuan)(chuan)感器(qi)構(gou)成(cheng)(cheng)涂覆資料(liao)融化、焊(han)點(dian)開(kai)化、彈性(xing)體內(nei)應力發(fa)生(sheng)結構(gou)改動等疑問；粉塵、濕潤對(dui)稱(cheng)重(zhong)傳(chuan)(chuan)(chuan)感器(qi)構(gou)成(cheng)(cheng)短路的(de)影(ying)響；在(zai)腐蝕性(xing)較(jiao)高的(de)環(huan)境下(xia)會構(gou)成(cheng)(cheng)稱(cheng)重(zhong)傳(chuan)(chuan)(chuan)感器(qi)彈性(xing)體受損或發(fa)生(sheng)短路表象；電磁場對(dui)稱(cheng)重(zhong)傳(chuan)(chuan)(chuan)感器(qi)輸出(chu)會發(fa)生(sheng)攪擾。相(xiang)應的(de)環(huan)境要(yao)素下(xia)咱們有必(bi)要(yao)選(xuan)擇對(dui)應的(de)稱(cheng)重(zhong)傳(chuan)(chuan)(chuan)感器(qi)才調(diao)滿足必(bi)要(yao)的(de)稱(cheng)重(zhong)央求。

  通過對稱重(zhong)傳感(gan)器的數(shu)量和量程(cheng)原理(li)的了(le)解(jie)，相(xiang)信大(da)家對稱重(zhong)傳感(gan)器有了(le)一定的了(le)解(jie)。
