一(yi)般(ban)來說，傳感(gan)(gan)器(qi)的(de)(de)量(liang)程(cheng)越接近分配到每(mei)個(ge)傳感(gan)(gan)器(qi)的(de)(de)載荷(he)，其(qi)稱(cheng)(cheng)量(liang)的(de)(de)準確(que)(que)度就(jiu)越高(gao)。但在實習運用(yong)時(shi)，因(yin)為(wei)加在傳感(gan)(gan)器(qi)上(shang)的(de)(de)載荷(he)除被(bei)稱(cheng)(cheng)物體外，還(huan)存(cun)在秤體自(zi)重、皮(pi)重、偏載及振動沖擊等載荷(he)，因(yin)此選用(yong)傳感(gan)(gan)器(qi)量(liang)程(cheng)時(shi)，要考(kao)慮諸多方(fang)面(mian)的(de)(de)要素，確(que)(que)保(bao)傳感(gan)(gan)器(qi)的(de)(de)安(an)全(quan)和壽數。今天說下(xia)稱(cheng)(cheng)重傳感(gan)(gan)器(qi)的(de)(de)數量(liang)和量(liang)程(cheng)原理：

  1、稱重傳感器(qi)的數量(liang)和量(liang)程

  一般應(ying)使(shi)稱(cheng)(cheng)(cheng)(cheng)重(zhong)(zhong)傳(chuan)(chuan)感(gan)器(qi)(qi)(qi)(qi)在(zai)(zai)其30%～70%量(liang)(liang)程(cheng)內(nei)工(gong)作(zuo)。但對于(yu)(yu)一些在(zai)(zai)運用(yong)過(guo)程(cheng)中存(cun)在(zai)(zai)較(jiao)大(da)沖擊(ji)力(li)的(de)衡(heng)(heng)器(qi)(qi)(qi)(qi)，如動態軌(gui)道衡(heng)(heng)、動態汽車(che)衡(heng)(heng)、鋼(gang)材秤(cheng)(cheng)等(deng)，在(zai)(zai)選(xuan)(xuan)用(yong)稱(cheng)(cheng)(cheng)(cheng)重(zhong)(zhong)傳(chuan)(chuan)感(gan)器(qi)(qi)(qi)(qi)時(shi)，一般要拓(tuo)展其量(liang)(liang)程(cheng)，使(shi)稱(cheng)(cheng)(cheng)(cheng)重(zhong)(zhong)傳(chuan)(chuan)感(gan)器(qi)(qi)(qi)(qi)在(zai)(zai)其量(liang)(liang)程(cheng)的(de)20%～30%以內(nei)工(gong)作(zuo)，使(shi)稱(cheng)(cheng)(cheng)(cheng)重(zhong)(zhong)傳(chuan)(chuan)感(gan)器(qi)(qi)(qi)(qi)的(de)稱(cheng)(cheng)(cheng)(cheng)量(liang)(liang)儲(chu)藏量(liang)(liang)程(cheng)增大(da)，以確保(bao)稱(cheng)(cheng)(cheng)(cheng)重(zhong)(zhong)傳(chuan)(chuan)感(gan)器(qi)(qi)(qi)(qi)的(de)運用(yong)安(an)(an)全和(he)壽數。稱(cheng)(cheng)(cheng)(cheng)重(zhong)(zhong)傳(chuan)(chuan)感(gan)器(qi)(qi)(qi)(qi)型(xing)式(shi)的(de)選(xuan)(xuan)擇首(shou)要取決于(yu)(yu)稱(cheng)(cheng)(cheng)(cheng)量(liang)(liang)的(de)類型(xing)和(he)設備空間，確保(bao)設備適宜(yi)，稱(cheng)(cheng)(cheng)(cheng)量(liang)(liang)安(an)(an)全可靠(kao)；另一方面，要考慮稱(cheng)(cheng)(cheng)(cheng)重(zhong)(zhong)傳(chuan)(chuan)感(gan)器(qi)(qi)(qi)(qi)制造廠的(de)建議(yi)。制造廠一般會根據稱(cheng)(cheng)(cheng)(cheng)重(zhong)(zhong)傳(chuan)(chuan)感(gan)器(qi)(qi)(qi)(qi)的(de)受力(li)情況、功用(yong)政(zheng)策、設備方法(fa)、結(jie)構型(xing)式(shi)、彈性體(ti)的(de)資料等(deng)特征規矩稱(cheng)(cheng)(cheng)(cheng)重(zhong)(zhong)傳(chuan)(chuan)感(gan)器(qi)(qi)(qi)(qi)的(de)適用(yong)計劃，比如鋁式(shi)懸(xuan)臂梁稱(cheng)(cheng)(cheng)(cheng)重(zhong)(zhong)傳(chuan)(chuan)感(gan)器(qi)(qi)(qi)(qi)適用(yong)于(yu)(yu)計價秤(cheng)(cheng)、平臺秤(cheng)(cheng)、案秤(cheng)(cheng)等(deng)，鋼(gang)式(shi)懸(xuan)臂梁稱(cheng)(cheng)(cheng)(cheng)重(zhong)(zhong)傳(chuan)(chuan)感(gan)器(qi)(qi)(qi)(qi)適用(yong)于(yu)(yu)料斗秤(cheng)(cheng)、電(dian)子皮帶(dai)秤(cheng)(cheng)、分(fen)選(xuan)(xuan)秤(cheng)(cheng)等(deng)，鋼(gang)質橋(qiao)式(shi)稱(cheng)(cheng)(cheng)(cheng)重(zhong)(zhong)傳(chuan)(chuan)感(gan)器(qi)(qi)(qi)(qi)適用(yong)于(yu)(yu)軌(gui)道衡(heng)(heng)、汽車(che)衡(heng)(heng)、天車(che)秤(cheng)(cheng)等(deng)，柱式(shi)稱(cheng)(cheng)(cheng)(cheng)重(zhong)(zhong)傳(chuan)(chuan)感(gan)器(qi)(qi)(qi)(qi)適用(yong)于(yu)(yu)汽車(che)衡(heng)(heng)、動態軌(gui)道衡(heng)(heng)、大(da)噸位料斗秤(cheng)(cheng)等(deng)。稱(cheng)(cheng)(cheng)(cheng)重(zhong)(zhong)傳(chuan)(chuan)感(gan)器(qi)(qi)(qi)(qi)

  2、稱重傳感器(qi)的準確度等級(ji)選(xuan)擇

  稱(cheng)(cheng)重(zhong)(zhong)傳感器的(de)(de)準確(que)度等級(ji)包括(kuo)稱(cheng)(cheng)重(zhong)(zhong)傳感器的(de)(de)非線(xian)性(xing)、蠕變、重(zhong)(zhong)復性(xing)、滯后、靈敏度等技術政策(ce)。在選用(yong)的(de)(de)時(shi)分不應(ying)當盲目尋求(qiu)高(gao)等級(ji)的(de)(de)稱(cheng)(cheng)重(zhong)(zhong)傳感器，應(ying)當考慮電(dian)子衡的(de)(de)準確(que)度等級(ji)和本(ben)錢。一(yi)般情況下，選用(yong)稱(cheng)(cheng)重(zhong)(zhong)傳感器的(de)(de)總精度為非線(xian)性(xing)、不重(zhong)(zhong)復性(xing)和滯后三項政策(ce)的(de)(de)之和的(de)(de)均方根值略高(gao)于秤的(de)(de)精度。稱(cheng)(cheng)重(zhong)(zhong)傳感器

  3、各種類型稱重傳感(gan)器(qi)的運用計劃

  選(xuan)用的稱重傳(chuan)感器(qi)(qi)須滿足表(biao)面(mian)輸入靈敏度(du)(du)(du)的央(yang)求，須可以與(yu)所(suo)選(xuan)表(biao)面(mian)匹配(pei)，滿足整(zheng)臺電子秤(cheng)(cheng)準確度(du)(du)(du)的央(yang)求。一(yi)(yi)臺電子秤(cheng)(cheng)首要是由(you)機械組織、稱重傳(chuan)感器(qi)(qi)、表(biao)面(mian)三有些構(gou)成(cheng)，在對稱重傳(chuan)感器(qi)(qi)準確度(du)(du)(du)選(xuan)擇的時分，應(ying)使稱重傳(chuan)感器(qi)(qi)的準確度(du)(du)(du)略高于理(li)論核算值(zhi)，因(yin)為理(li)論一(yi)(yi)般遭(zao)到客觀條(tiao)件的束縛(fu)，如機械結構(gou)的強(qiang)度(du)(du)(du)、表(biao)面(mian)的功用、秤(cheng)(cheng)的工作環境惡(e)劣程度(du)(du)(du)等要素都直(zhi)接影響到秤(cheng)(cheng)的準確度(du)(du)(du)。因(yin)此(ci)要從各(ge)方面(mian)行進央(yang)求，統(tong)籌經濟(ji)效益，確保抵(di)達意圖。

  4、運用(yong)環境

  一(yi)般情況(kuang)下，高溫環(huan)(huan)境(jing)對(dui)稱重(zhong)傳(chuan)(chuan)感(gan)器(qi)(qi)構成(cheng)涂覆(fu)資料融化(hua)、焊點開化(hua)、彈性(xing)體內應(ying)(ying)力發(fa)生結構改動等疑(yi)問；粉塵、濕潤對(dui)稱重(zhong)傳(chuan)(chuan)感(gan)器(qi)(qi)構成(cheng)短(duan)路的影響；在腐蝕性(xing)較高的環(huan)(huan)境(jing)下會構成(cheng)稱重(zhong)傳(chuan)(chuan)感(gan)器(qi)(qi)彈性(xing)體受(shou)損或發(fa)生短(duan)路表象；電磁場對(dui)稱重(zhong)傳(chuan)(chuan)感(gan)器(qi)(qi)輸出會發(fa)生攪(jiao)擾。相應(ying)(ying)的環(huan)(huan)境(jing)要(yao)素下咱們(men)有必(bi)要(yao)選擇對(dui)應(ying)(ying)的稱重(zhong)傳(chuan)(chuan)感(gan)器(qi)(qi)才(cai)調滿足必(bi)要(yao)的稱重(zhong)央求(qiu)。

  通過對(dui)稱重傳感器(qi)的(de)數量(liang)和量(liang)程原理的(de)了解(jie)，相(xiang)信大(da)家對(dui)稱重傳感器(qi)有了一定的(de)了解(jie)。
