一般(ban)來說，傳(chuan)(chuan)感器(qi)的量(liang)程(cheng)越接近分配(pei)到每個傳(chuan)(chuan)感器(qi)的載荷，其(qi)稱(cheng)量(liang)的準確(que)度就(jiu)越高。但在實習(xi)運用時(shi)，因(yin)為加(jia)在傳(chuan)(chuan)感器(qi)上的載荷除被稱(cheng)物體(ti)外，還存在秤體(ti)自重(zhong)、皮重(zhong)、偏載及振動沖(chong)擊等載荷，因(yin)此選用傳(chuan)(chuan)感器(qi)量(liang)程(cheng)時(shi)，要(yao)考慮諸多方面的要(yao)素，確(que)保(bao)傳(chuan)(chuan)感器(qi)的安全和(he)(he)壽數。今天說下稱(cheng)重(zhong)傳(chuan)(chuan)感器(qi)的數量(liang)和(he)(he)量(liang)程(cheng)原理：

  1、稱重傳感(gan)器(qi)的數(shu)量(liang)和量(liang)程

  一般(ban)應使(shi)稱(cheng)(cheng)重(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)傳(chuan)(chuan)感(gan)(gan)器(qi)(qi)(qi)(qi)在(zai)其(qi)30%～70%量(liang)(liang)程(cheng)(cheng)(cheng)(cheng)內工作。但對于(yu)一些在(zai)運用(yong)(yong)(yong)過程(cheng)(cheng)(cheng)(cheng)中(zhong)存在(zai)較大(da)沖擊力(li)的衡器(qi)(qi)(qi)(qi)，如動(dong)態軌道衡、動(dong)態汽車(che)(che)衡、鋼材秤(cheng)等(deng)(deng)，在(zai)選用(yong)(yong)(yong)稱(cheng)(cheng)重(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)傳(chuan)(chuan)感(gan)(gan)器(qi)(qi)(qi)(qi)時(shi)，一般(ban)要(yao)拓(tuo)展其(qi)量(liang)(liang)程(cheng)(cheng)(cheng)(cheng)，使(shi)稱(cheng)(cheng)重(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)傳(chuan)(chuan)感(gan)(gan)器(qi)(qi)(qi)(qi)在(zai)其(qi)量(liang)(liang)程(cheng)(cheng)(cheng)(cheng)的20%～30%以內工作，使(shi)稱(cheng)(cheng)重(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)傳(chuan)(chuan)感(gan)(gan)器(qi)(qi)(qi)(qi)的稱(cheng)(cheng)量(liang)(liang)儲藏量(liang)(liang)程(cheng)(cheng)(cheng)(cheng)增大(da)，以確保稱(cheng)(cheng)重(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)傳(chuan)(chuan)感(gan)(gan)器(qi)(qi)(qi)(qi)的運用(yong)(yong)(yong)安全(quan)和壽數。稱(cheng)(cheng)重(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)傳(chuan)(chuan)感(gan)(gan)器(qi)(qi)(qi)(qi)型式的選擇首要(yao)取決于(yu)稱(cheng)(cheng)量(liang)(liang)的類型和設(she)(she)備空間，確保設(she)(she)備適(shi)宜，稱(cheng)(cheng)量(liang)(liang)安全(quan)可(ke)靠；另(ling)一方面，要(yao)考(kao)慮稱(cheng)(cheng)重(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)傳(chuan)(chuan)感(gan)(gan)器(qi)(qi)(qi)(qi)制造廠(chang)的建(jian)議。制造廠(chang)一般(ban)會根據稱(cheng)(cheng)重(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)傳(chuan)(chuan)感(gan)(gan)器(qi)(qi)(qi)(qi)的受(shou)力(li)情況、功(gong)用(yong)(yong)(yong)政策、設(she)(she)備方法、結構型式、彈性體的資料等(deng)(deng)特征規矩稱(cheng)(cheng)重(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)傳(chuan)(chuan)感(gan)(gan)器(qi)(qi)(qi)(qi)的適(shi)用(yong)(yong)(yong)計(ji)劃(hua)，比(bi)如鋁(lv)式懸臂梁稱(cheng)(cheng)重(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)傳(chuan)(chuan)感(gan)(gan)器(qi)(qi)(qi)(qi)適(shi)用(yong)(yong)(yong)于(yu)計(ji)價秤(cheng)、平臺秤(cheng)、案秤(cheng)等(deng)(deng)，鋼式懸臂梁稱(cheng)(cheng)重(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)傳(chuan)(chuan)感(gan)(gan)器(qi)(qi)(qi)(qi)適(shi)用(yong)(yong)(yong)于(yu)料斗秤(cheng)、電子(zi)皮帶秤(cheng)、分選秤(cheng)等(deng)(deng)，鋼質橋式稱(cheng)(cheng)重(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)傳(chuan)(chuan)感(gan)(gan)器(qi)(qi)(qi)(qi)適(shi)用(yong)(yong)(yong)于(yu)軌道衡、汽車(che)(che)衡、天車(che)(che)秤(cheng)等(deng)(deng)，柱式稱(cheng)(cheng)重(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)傳(chuan)(chuan)感(gan)(gan)器(qi)(qi)(qi)(qi)適(shi)用(yong)(yong)(yong)于(yu)汽車(che)(che)衡、動(dong)態軌道衡、大(da)噸位料斗秤(cheng)等(deng)(deng)。稱(cheng)(cheng)重(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)傳(chuan)(chuan)感(gan)(gan)器(qi)(qi)(qi)(qi)

  2、稱(cheng)重傳感器的準確度等級選擇

  稱重(zhong)(zhong)傳感(gan)器(qi)的(de)(de)(de)準確(que)度(du)等(deng)級(ji)包括稱重(zhong)(zhong)傳感(gan)器(qi)的(de)(de)(de)非線性(xing)、蠕(ru)變、重(zhong)(zhong)復性(xing)、滯(zhi)后(hou)、靈敏度(du)等(deng)技(ji)術政策(ce)。在選用的(de)(de)(de)時分不(bu)應(ying)當盲目尋(xun)求高等(deng)級(ji)的(de)(de)(de)稱重(zhong)(zhong)傳感(gan)器(qi)，應(ying)當考慮電子衡的(de)(de)(de)準確(que)度(du)等(deng)級(ji)和(he)本錢(qian)。一(yi)般情況下，選用稱重(zhong)(zhong)傳感(gan)器(qi)的(de)(de)(de)總精度(du)為非線性(xing)、不(bu)重(zhong)(zhong)復性(xing)和(he)滯(zhi)后(hou)三(san)項政策(ce)的(de)(de)(de)之和(he)的(de)(de)(de)均方根值略高于(yu)秤(cheng)的(de)(de)(de)精度(du)。稱重(zhong)(zhong)傳感(gan)器(qi)

  3、各種類(lei)型稱重傳感器的運用計劃

  選用的(de)稱重(zhong)傳(chuan)感器(qi)須滿足(zu)表面(mian)(mian)輸入靈敏度(du)(du)(du)的(de)央求，須可以與所選表面(mian)(mian)匹配，滿足(zu)整臺電子秤(cheng)準(zhun)確(que)度(du)(du)(du)的(de)央求。一(yi)臺電子秤(cheng)首要是由(you)機械組(zu)織、稱重(zhong)傳(chuan)感器(qi)、表面(mian)(mian)三有些構(gou)成，在對稱重(zhong)傳(chuan)感器(qi)準(zhun)確(que)度(du)(du)(du)選擇的(de)時(shi)分，應使稱重(zhong)傳(chuan)感器(qi)的(de)準(zhun)確(que)度(du)(du)(du)略高于理論(lun)(lun)核算值，因為(wei)理論(lun)(lun)一(yi)般遭到客觀(guan)條件的(de)束縛，如機械結構(gou)的(de)強(qiang)度(du)(du)(du)、表面(mian)(mian)的(de)功用、秤(cheng)的(de)工作環境惡劣程(cheng)度(du)(du)(du)等要素都直接影響到秤(cheng)的(de)準(zhun)確(que)度(du)(du)(du)。因此要從各(ge)方(fang)面(mian)(mian)行(xing)進央求，統籌經濟(ji)效益，確(que)保(bao)抵達意圖。

  4、運用環(huan)境

  一般情況(kuang)下，高溫環(huan)(huan)境(jing)對(dui)稱(cheng)重(zhong)傳(chuan)感(gan)(gan)器(qi)構(gou)成涂覆(fu)資料融化(hua)、焊點(dian)開(kai)化(hua)、彈(dan)性(xing)體(ti)內應(ying)力(li)發生結構(gou)改動等(deng)疑(yi)問；粉塵(chen)、濕潤對(dui)稱(cheng)重(zhong)傳(chuan)感(gan)(gan)器(qi)構(gou)成短(duan)路的(de)影響(xiang)；在腐蝕性(xing)較高的(de)環(huan)(huan)境(jing)下會構(gou)成稱(cheng)重(zhong)傳(chuan)感(gan)(gan)器(qi)彈(dan)性(xing)體(ti)受損或發生短(duan)路表象；電磁場對(dui)稱(cheng)重(zhong)傳(chuan)感(gan)(gan)器(qi)輸出會發生攪擾。相應(ying)的(de)環(huan)(huan)境(jing)要(yao)素下咱們有必要(yao)選擇(ze)對(dui)應(ying)的(de)稱(cheng)重(zhong)傳(chuan)感(gan)(gan)器(qi)才(cai)調滿(man)足必要(yao)的(de)稱(cheng)重(zhong)央求。

  通過對稱重傳感器(qi)的數(shu)量(liang)和量(liang)程原理的了(le)解，相信大家對稱重傳感器(qi)有(you)了(le)一定的了(le)解。
