一般來說(shuo)，傳感器(qi)的(de)量(liang)程(cheng)越接(jie)近分配(pei)到每個傳感器(qi)的(de)載(zai)(zai)荷，其(qi)稱量(liang)的(de)準(zhun)確度就越高。但在(zai)實習運用時(shi)，因為加在(zai)傳感器(qi)上的(de)載(zai)(zai)荷除被(bei)稱物體(ti)外，還(huan)存在(zai)秤體(ti)自重、皮重、偏載(zai)(zai)及(ji)振動沖擊等載(zai)(zai)荷，因此選用傳感器(qi)量(liang)程(cheng)時(shi)，要考慮諸多方面的(de)要素，確保(bao)傳感器(qi)的(de)安全和(he)壽數。今天(tian)說(shuo)下稱重傳感器(qi)的(de)數量(liang)和(he)量(liang)程(cheng)原(yuan)理(li)：

  1、稱重(zhong)傳感器的數(shu)量和量程

  一(yi)(yi)般應使稱(cheng)(cheng)(cheng)(cheng)(cheng)(cheng)(cheng)重(zhong)(zhong)(zhong)(zhong)(zhong)傳(chuan)(chuan)(chuan)感(gan)(gan)(gan)(gan)(gan)器(qi)(qi)(qi)(qi)在其(qi)(qi)30%～70%量(liang)程內(nei)工作。但對于(yu)(yu)(yu)(yu)一(yi)(yi)些在運用(yong)(yong)過程中(zhong)存(cun)在較大沖擊力(li)的衡(heng)(heng)(heng)器(qi)(qi)(qi)(qi)，如動態軌(gui)道(dao)衡(heng)(heng)(heng)、動態汽(qi)車衡(heng)(heng)(heng)、鋼(gang)(gang)材(cai)秤(cheng)等(deng)，在選用(yong)(yong)稱(cheng)(cheng)(cheng)(cheng)(cheng)(cheng)(cheng)重(zhong)(zhong)(zhong)(zhong)(zhong)傳(chuan)(chuan)(chuan)感(gan)(gan)(gan)(gan)(gan)器(qi)(qi)(qi)(qi)時，一(yi)(yi)般要(yao)拓展其(qi)(qi)量(liang)程，使稱(cheng)(cheng)(cheng)(cheng)(cheng)(cheng)(cheng)重(zhong)(zhong)(zhong)(zhong)(zhong)傳(chuan)(chuan)(chuan)感(gan)(gan)(gan)(gan)(gan)器(qi)(qi)(qi)(qi)在其(qi)(qi)量(liang)程的20%～30%以內(nei)工作，使稱(cheng)(cheng)(cheng)(cheng)(cheng)(cheng)(cheng)重(zhong)(zhong)(zhong)(zhong)(zhong)傳(chuan)(chuan)(chuan)感(gan)(gan)(gan)(gan)(gan)器(qi)(qi)(qi)(qi)的稱(cheng)(cheng)(cheng)(cheng)(cheng)(cheng)(cheng)量(liang)儲藏量(liang)程增大，以確保(bao)稱(cheng)(cheng)(cheng)(cheng)(cheng)(cheng)(cheng)重(zhong)(zhong)(zhong)(zhong)(zhong)傳(chuan)(chuan)(chuan)感(gan)(gan)(gan)(gan)(gan)器(qi)(qi)(qi)(qi)的運用(yong)(yong)安全和壽(shou)數。稱(cheng)(cheng)(cheng)(cheng)(cheng)(cheng)(cheng)重(zhong)(zhong)(zhong)(zhong)(zhong)傳(chuan)(chuan)(chuan)感(gan)(gan)(gan)(gan)(gan)器(qi)(qi)(qi)(qi)型(xing)式的選擇首要(yao)取決于(yu)(yu)(yu)(yu)稱(cheng)(cheng)(cheng)(cheng)(cheng)(cheng)(cheng)量(liang)的類型(xing)和設(she)備(bei)空間，確保(bao)設(she)備(bei)適(shi)宜，稱(cheng)(cheng)(cheng)(cheng)(cheng)(cheng)(cheng)量(liang)安全可靠；另(ling)一(yi)(yi)方面，要(yao)考(kao)慮稱(cheng)(cheng)(cheng)(cheng)(cheng)(cheng)(cheng)重(zhong)(zhong)(zhong)(zhong)(zhong)傳(chuan)(chuan)(chuan)感(gan)(gan)(gan)(gan)(gan)器(qi)(qi)(qi)(qi)制(zhi)造廠的建議。制(zhi)造廠一(yi)(yi)般會根據(ju)稱(cheng)(cheng)(cheng)(cheng)(cheng)(cheng)(cheng)重(zhong)(zhong)(zhong)(zhong)(zhong)傳(chuan)(chuan)(chuan)感(gan)(gan)(gan)(gan)(gan)器(qi)(qi)(qi)(qi)的受力(li)情況、功用(yong)(yong)政策、設(she)備(bei)方法(fa)、結(jie)構型(xing)式、彈性(xing)體的資料等(deng)特征規(gui)矩稱(cheng)(cheng)(cheng)(cheng)(cheng)(cheng)(cheng)重(zhong)(zhong)(zhong)(zhong)(zhong)傳(chuan)(chuan)(chuan)感(gan)(gan)(gan)(gan)(gan)器(qi)(qi)(qi)(qi)的適(shi)用(yong)(yong)計劃，比(bi)如鋁式懸(xuan)臂梁稱(cheng)(cheng)(cheng)(cheng)(cheng)(cheng)(cheng)重(zhong)(zhong)(zhong)(zhong)(zhong)傳(chuan)(chuan)(chuan)感(gan)(gan)(gan)(gan)(gan)器(qi)(qi)(qi)(qi)適(shi)用(yong)(yong)于(yu)(yu)(yu)(yu)計價秤(cheng)、平臺秤(cheng)、案秤(cheng)等(deng)，鋼(gang)(gang)式懸(xuan)臂梁稱(cheng)(cheng)(cheng)(cheng)(cheng)(cheng)(cheng)重(zhong)(zhong)(zhong)(zhong)(zhong)傳(chuan)(chuan)(chuan)感(gan)(gan)(gan)(gan)(gan)器(qi)(qi)(qi)(qi)適(shi)用(yong)(yong)于(yu)(yu)(yu)(yu)料斗(dou)秤(cheng)、電子皮帶秤(cheng)、分選秤(cheng)等(deng)，鋼(gang)(gang)質橋式稱(cheng)(cheng)(cheng)(cheng)(cheng)(cheng)(cheng)重(zhong)(zhong)(zhong)(zhong)(zhong)傳(chuan)(chuan)(chuan)感(gan)(gan)(gan)(gan)(gan)器(qi)(qi)(qi)(qi)適(shi)用(yong)(yong)于(yu)(yu)(yu)(yu)軌(gui)道(dao)衡(heng)(heng)(heng)、汽(qi)車衡(heng)(heng)(heng)、天(tian)車秤(cheng)等(deng)，柱式稱(cheng)(cheng)(cheng)(cheng)(cheng)(cheng)(cheng)重(zhong)(zhong)(zhong)(zhong)(zhong)傳(chuan)(chuan)(chuan)感(gan)(gan)(gan)(gan)(gan)器(qi)(qi)(qi)(qi)適(shi)用(yong)(yong)于(yu)(yu)(yu)(yu)汽(qi)車衡(heng)(heng)(heng)、動態軌(gui)道(dao)衡(heng)(heng)(heng)、大噸位料斗(dou)秤(cheng)等(deng)。稱(cheng)(cheng)(cheng)(cheng)(cheng)(cheng)(cheng)重(zhong)(zhong)(zhong)(zhong)(zhong)傳(chuan)(chuan)(chuan)感(gan)(gan)(gan)(gan)(gan)器(qi)(qi)(qi)(qi)

  2、稱重傳(chuan)感器的準(zhun)確(que)度(du)等(deng)級選擇

  稱(cheng)重(zhong)傳(chuan)感器的(de)(de)準確度(du)(du)等級包括(kuo)稱(cheng)重(zhong)傳(chuan)感器的(de)(de)非線性(xing)、蠕變、重(zhong)復性(xing)、滯(zhi)后、靈敏度(du)(du)等技(ji)術政策。在選(xuan)用的(de)(de)時(shi)分不應當盲目(mu)尋(xun)求(qiu)高等級的(de)(de)稱(cheng)重(zhong)傳(chuan)感器，應當考慮電(dian)子衡(heng)的(de)(de)準確度(du)(du)等級和(he)本錢。一般情況下，選(xuan)用稱(cheng)重(zhong)傳(chuan)感器的(de)(de)總精度(du)(du)為非線性(xing)、不重(zhong)復性(xing)和(he)滯(zhi)后三項政策的(de)(de)之和(he)的(de)(de)均方根值略高于秤的(de)(de)精度(du)(du)。稱(cheng)重(zhong)傳(chuan)感器

  3、各種類型稱重傳感器的運用計劃

  選用的稱重(zhong)傳感(gan)器須滿(man)足表面(mian)(mian)輸入靈敏(min)度(du)(du)的央求，須可以與(yu)所選表面(mian)(mian)匹配，滿(man)足整臺(tai)電(dian)(dian)子秤(cheng)準確(que)(que)度(du)(du)的央求。一(yi)臺(tai)電(dian)(dian)子秤(cheng)首要(yao)是由機械組織、稱重(zhong)傳感(gan)器、表面(mian)(mian)三有(you)些構成，在對稱重(zhong)傳感(gan)器準確(que)(que)度(du)(du)選擇的時分，應使稱重(zhong)傳感(gan)器的準確(que)(que)度(du)(du)略高于理(li)(li)論核算值(zhi)，因(yin)為理(li)(li)論一(yi)般遭到(dao)客觀條件的束縛，如機械結構的強度(du)(du)、表面(mian)(mian)的功用、秤(cheng)的工作環境惡劣程(cheng)度(du)(du)等要(yao)素都(dou)直接(jie)影(ying)響到(dao)秤(cheng)的準確(que)(que)度(du)(du)。因(yin)此(ci)要(yao)從(cong)各方面(mian)(mian)行進(jin)央求，統(tong)籌經濟效(xiao)益，確(que)(que)保抵達意(yi)圖。

  4、運用環境

  一(yi)般情況(kuang)下，高(gao)溫環境(jing)對(dui)稱(cheng)(cheng)(cheng)重傳感(gan)器(qi)構成(cheng)涂覆資(zi)料融(rong)化、焊點開化、彈(dan)性體內應(ying)力發(fa)(fa)生(sheng)結構改動等疑問(wen)；粉塵、濕(shi)潤對(dui)稱(cheng)(cheng)(cheng)重傳感(gan)器(qi)構成(cheng)短路的(de)(de)影(ying)響；在(zai)腐蝕性較(jiao)高(gao)的(de)(de)環境(jing)下會構成(cheng)稱(cheng)(cheng)(cheng)重傳感(gan)器(qi)彈(dan)性體受損或發(fa)(fa)生(sheng)短路表(biao)象；電(dian)磁場對(dui)稱(cheng)(cheng)(cheng)重傳感(gan)器(qi)輸出會發(fa)(fa)生(sheng)攪擾。相應(ying)的(de)(de)環境(jing)要(yao)(yao)素下咱們有必要(yao)(yao)選擇對(dui)應(ying)的(de)(de)稱(cheng)(cheng)(cheng)重傳感(gan)器(qi)才調滿足必要(yao)(yao)的(de)(de)稱(cheng)(cheng)(cheng)重央(yang)求。

  通(tong)過對稱重(zhong)傳感(gan)(gan)器(qi)的(de)數量和(he)量程原理的(de)了解(jie)(jie)，相(xiang)信大家對稱重(zhong)傳感(gan)(gan)器(qi)有(you)了一定的(de)了解(jie)(jie)。
