一般來說，傳(chuan)感(gan)(gan)(gan)器(qi)的(de)量(liang)(liang)(liang)(liang)程越接近分配到每(mei)個傳(chuan)感(gan)(gan)(gan)器(qi)的(de)載荷(he)，其稱量(liang)(liang)(liang)(liang)的(de)準確度(du)就(jiu)越高。但在實習運用(yong)時(shi)，因為加在傳(chuan)感(gan)(gan)(gan)器(qi)上的(de)載荷(he)除被稱物體(ti)外，還存在秤體(ti)自重、皮重、偏載及(ji)振動沖擊等載荷(he)，因此選用(yong)傳(chuan)感(gan)(gan)(gan)器(qi)量(liang)(liang)(liang)(liang)程時(shi)，要考慮諸(zhu)多(duo)方面的(de)要素，確保傳(chuan)感(gan)(gan)(gan)器(qi)的(de)安全和壽數。今天說下稱重傳(chuan)感(gan)(gan)(gan)器(qi)的(de)數量(liang)(liang)(liang)(liang)和量(liang)(liang)(liang)(liang)程原理：

  1、稱重傳感(gan)器的數量(liang)和量(liang)程

  一(yi)(yi)般應使(shi)(shi)稱(cheng)(cheng)重(zhong)(zhong)(zhong)(zhong)(zhong)傳(chuan)(chuan)感(gan)(gan)(gan)器(qi)(qi)(qi)(qi)在(zai)其30%～70%量(liang)程(cheng)內工(gong)作。但(dan)對于(yu)一(yi)(yi)些在(zai)運用(yong)(yong)(yong)過(guo)程(cheng)中存在(zai)較(jiao)大沖(chong)擊力的(de)(de)衡(heng)(heng)(heng)(heng)器(qi)(qi)(qi)(qi)，如動態軌道(dao)衡(heng)(heng)(heng)(heng)、動態汽(qi)車衡(heng)(heng)(heng)(heng)、鋼材(cai)秤(cheng)等(deng)(deng)，在(zai)選(xuan)用(yong)(yong)(yong)稱(cheng)(cheng)重(zhong)(zhong)(zhong)(zhong)(zhong)傳(chuan)(chuan)感(gan)(gan)(gan)器(qi)(qi)(qi)(qi)時(shi)，一(yi)(yi)般要拓(tuo)展其量(liang)程(cheng)，使(shi)(shi)稱(cheng)(cheng)重(zhong)(zhong)(zhong)(zhong)(zhong)傳(chuan)(chuan)感(gan)(gan)(gan)器(qi)(qi)(qi)(qi)在(zai)其量(liang)程(cheng)的(de)(de)20%～30%以(yi)(yi)內工(gong)作，使(shi)(shi)稱(cheng)(cheng)重(zhong)(zhong)(zhong)(zhong)(zhong)傳(chuan)(chuan)感(gan)(gan)(gan)器(qi)(qi)(qi)(qi)的(de)(de)稱(cheng)(cheng)量(liang)儲藏量(liang)程(cheng)增大，以(yi)(yi)確(que)保(bao)(bao)稱(cheng)(cheng)重(zhong)(zhong)(zhong)(zhong)(zhong)傳(chuan)(chuan)感(gan)(gan)(gan)器(qi)(qi)(qi)(qi)的(de)(de)運用(yong)(yong)(yong)安全和(he)壽數。稱(cheng)(cheng)重(zhong)(zhong)(zhong)(zhong)(zhong)傳(chuan)(chuan)感(gan)(gan)(gan)器(qi)(qi)(qi)(qi)型式(shi)(shi)的(de)(de)選(xuan)擇(ze)首要取決于(yu)稱(cheng)(cheng)量(liang)的(de)(de)類型和(he)設備(bei)空間，確(que)保(bao)(bao)設備(bei)適(shi)宜，稱(cheng)(cheng)量(liang)安全可靠；另一(yi)(yi)方面(mian)，要考慮稱(cheng)(cheng)重(zhong)(zhong)(zhong)(zhong)(zhong)傳(chuan)(chuan)感(gan)(gan)(gan)器(qi)(qi)(qi)(qi)制造廠的(de)(de)建(jian)議。制造廠一(yi)(yi)般會根據(ju)稱(cheng)(cheng)重(zhong)(zhong)(zhong)(zhong)(zhong)傳(chuan)(chuan)感(gan)(gan)(gan)器(qi)(qi)(qi)(qi)的(de)(de)受力情況、功用(yong)(yong)(yong)政策、設備(bei)方法、結構型式(shi)(shi)、彈性體的(de)(de)資料(liao)等(deng)(deng)特征規矩稱(cheng)(cheng)重(zhong)(zhong)(zhong)(zhong)(zhong)傳(chuan)(chuan)感(gan)(gan)(gan)器(qi)(qi)(qi)(qi)的(de)(de)適(shi)用(yong)(yong)(yong)計劃(hua)，比如鋁式(shi)(shi)懸(xuan)臂(bei)梁稱(cheng)(cheng)重(zhong)(zhong)(zhong)(zhong)(zhong)傳(chuan)(chuan)感(gan)(gan)(gan)器(qi)(qi)(qi)(qi)適(shi)用(yong)(yong)(yong)于(yu)計價秤(cheng)、平臺秤(cheng)、案秤(cheng)等(deng)(deng)，鋼式(shi)(shi)懸(xuan)臂(bei)梁稱(cheng)(cheng)重(zhong)(zhong)(zhong)(zhong)(zhong)傳(chuan)(chuan)感(gan)(gan)(gan)器(qi)(qi)(qi)(qi)適(shi)用(yong)(yong)(yong)于(yu)料(liao)斗秤(cheng)、電子皮帶秤(cheng)、分(fen)選(xuan)秤(cheng)等(deng)(deng)，鋼質橋式(shi)(shi)稱(cheng)(cheng)重(zhong)(zhong)(zhong)(zhong)(zhong)傳(chuan)(chuan)感(gan)(gan)(gan)器(qi)(qi)(qi)(qi)適(shi)用(yong)(yong)(yong)于(yu)軌道(dao)衡(heng)(heng)(heng)(heng)、汽(qi)車衡(heng)(heng)(heng)(heng)、天(tian)車秤(cheng)等(deng)(deng)，柱式(shi)(shi)稱(cheng)(cheng)重(zhong)(zhong)(zhong)(zhong)(zhong)傳(chuan)(chuan)感(gan)(gan)(gan)器(qi)(qi)(qi)(qi)適(shi)用(yong)(yong)(yong)于(yu)汽(qi)車衡(heng)(heng)(heng)(heng)、動態軌道(dao)衡(heng)(heng)(heng)(heng)、大噸(dun)位料(liao)斗秤(cheng)等(deng)(deng)。稱(cheng)(cheng)重(zhong)(zhong)(zhong)(zhong)(zhong)傳(chuan)(chuan)感(gan)(gan)(gan)器(qi)(qi)(qi)(qi)

  2、稱重傳感器的準確度等級選(xuan)擇

  稱(cheng)重傳(chuan)感(gan)器的(de)準確度(du)等級包括稱(cheng)重傳(chuan)感(gan)器的(de)非線性(xing)(xing)、蠕(ru)變、重復(fu)性(xing)(xing)、滯(zhi)后(hou)、靈敏度(du)等技術政策。在選用(yong)的(de)時分不(bu)應(ying)(ying)當(dang)(dang)盲目(mu)尋求高等級的(de)稱(cheng)重傳(chuan)感(gan)器，應(ying)(ying)當(dang)(dang)考慮電子衡(heng)的(de)準確度(du)等級和本錢。一(yi)般情(qing)況下，選用(yong)稱(cheng)重傳(chuan)感(gan)器的(de)總(zong)精(jing)度(du)為非線性(xing)(xing)、不(bu)重復(fu)性(xing)(xing)和滯(zhi)后(hou)三項政策的(de)之(zhi)和的(de)均方根(gen)值(zhi)略高于(yu)秤的(de)精(jing)度(du)。稱(cheng)重傳(chuan)感(gan)器

  3、各(ge)種類型稱重傳感器(qi)的運用計劃(hua)

  選用的(de)(de)稱(cheng)重(zhong)傳感器(qi)須(xu)滿(man)足表面輸入靈敏度(du)(du)(du)的(de)(de)央求，須(xu)可以與(yu)所(suo)選表面匹配，滿(man)足整臺電(dian)子(zi)秤(cheng)準(zhun)(zhun)(zhun)(zhun)確(que)度(du)(du)(du)的(de)(de)央求。一(yi)(yi)臺電(dian)子(zi)秤(cheng)首要是(shi)由機械組織(zhi)、稱(cheng)重(zhong)傳感器(qi)、表面三有些構成，在(zai)對(dui)稱(cheng)重(zhong)傳感器(qi)準(zhun)(zhun)(zhun)(zhun)確(que)度(du)(du)(du)選擇(ze)的(de)(de)時(shi)分，應(ying)使稱(cheng)重(zhong)傳感器(qi)的(de)(de)準(zhun)(zhun)(zhun)(zhun)確(que)度(du)(du)(du)略(lve)高于理論核算(suan)值，因(yin)為理論一(yi)(yi)般(ban)遭到客觀條件的(de)(de)束縛，如機械結構的(de)(de)強度(du)(du)(du)、表面的(de)(de)功用、秤(cheng)的(de)(de)工作環境惡(e)劣程度(du)(du)(du)等要素都直(zhi)接影響(xiang)到秤(cheng)的(de)(de)準(zhun)(zhun)(zhun)(zhun)確(que)度(du)(du)(du)。因(yin)此要從各方面行(xing)進央求，統籌(chou)經(jing)濟(ji)效益，確(que)保抵達(da)意圖。

  4、運用環(huan)境(jing)

  一般(ban)情況(kuang)下，高溫環(huan)境(jing)對(dui)稱(cheng)重(zhong)(zhong)傳(chuan)感器構(gou)成(cheng)涂覆(fu)資料融(rong)化(hua)、焊點開化(hua)、彈(dan)(dan)性體(ti)內應力發生結(jie)構(gou)改動等(deng)疑問；粉塵、濕潤對(dui)稱(cheng)重(zhong)(zhong)傳(chuan)感器構(gou)成(cheng)短路的影響(xiang)；在腐蝕(shi)性較高的環(huan)境(jing)下會構(gou)成(cheng)稱(cheng)重(zhong)(zhong)傳(chuan)感器彈(dan)(dan)性體(ti)受損(sun)或發生短路表象；電(dian)磁場對(dui)稱(cheng)重(zhong)(zhong)傳(chuan)感器輸出會發生攪擾。相應的環(huan)境(jing)要(yao)(yao)素下咱(zan)們有必(bi)要(yao)(yao)選擇(ze)對(dui)應的稱(cheng)重(zhong)(zhong)傳(chuan)感器才調滿足必(bi)要(yao)(yao)的稱(cheng)重(zhong)(zhong)央(yang)求。

  通過對稱(cheng)重傳感(gan)器的(de)數(shu)量和量程(cheng)原理的(de)了(le)解(jie)，相信大(da)家對稱(cheng)重傳感(gan)器有了(le)一定的(de)了(le)解(jie)。
