一(yi)般來(lai)說(shuo)，傳(chuan)(chuan)感(gan)(gan)器(qi)的(de)量(liang)程越(yue)接近分配到每個(ge)傳(chuan)(chuan)感(gan)(gan)器(qi)的(de)載(zai)荷，其稱(cheng)量(liang)的(de)準(zhun)確度就越(yue)高(gao)。但在實習運用(yong)(yong)時，因為加在傳(chuan)(chuan)感(gan)(gan)器(qi)上的(de)載(zai)荷除被稱(cheng)物(wu)體外，還存在秤體自重(zhong)(zhong)、皮重(zhong)(zhong)、偏載(zai)及(ji)振動沖擊等載(zai)荷，因此(ci)選用(yong)(yong)傳(chuan)(chuan)感(gan)(gan)器(qi)量(liang)程時，要(yao)(yao)考慮諸(zhu)多方面的(de)要(yao)(yao)素，確保傳(chuan)(chuan)感(gan)(gan)器(qi)的(de)安(an)全和壽數。今天說(shuo)下稱(cheng)重(zhong)(zhong)傳(chuan)(chuan)感(gan)(gan)器(qi)的(de)數量(liang)和量(liang)程原(yuan)理(li)：

  1、稱(cheng)重傳感器的數量(liang)和量(liang)程

  一(yi)(yi)般應使稱(cheng)(cheng)(cheng)(cheng)重(zhong)(zhong)(zhong)傳(chuan)(chuan)(chuan)(chuan)(chuan)感(gan)(gan)(gan)(gan)器(qi)(qi)在其30%～70%量(liang)(liang)程(cheng)內(nei)工作(zuo)(zuo)。但對(dui)于(yu)(yu)一(yi)(yi)些在運(yun)用(yong)過程(cheng)中存在較大(da)沖擊力的(de)(de)衡(heng)器(qi)(qi)，如(ru)動態(tai)軌道衡(heng)、動態(tai)汽(qi)(qi)車(che)衡(heng)、鋼(gang)材秤(cheng)(cheng)等(deng)(deng)，在選用(yong)稱(cheng)(cheng)(cheng)(cheng)重(zhong)(zhong)(zhong)傳(chuan)(chuan)(chuan)(chuan)(chuan)感(gan)(gan)(gan)(gan)器(qi)(qi)時，一(yi)(yi)般要拓展其量(liang)(liang)程(cheng)，使稱(cheng)(cheng)(cheng)(cheng)重(zhong)(zhong)(zhong)傳(chuan)(chuan)(chuan)(chuan)(chuan)感(gan)(gan)(gan)(gan)器(qi)(qi)在其量(liang)(liang)程(cheng)的(de)(de)20%～30%以內(nei)工作(zuo)(zuo)，使稱(cheng)(cheng)(cheng)(cheng)重(zhong)(zhong)(zhong)傳(chuan)(chuan)(chuan)(chuan)(chuan)感(gan)(gan)(gan)(gan)器(qi)(qi)的(de)(de)稱(cheng)(cheng)(cheng)(cheng)量(liang)(liang)儲藏量(liang)(liang)程(cheng)增(zeng)大(da)，以確保稱(cheng)(cheng)(cheng)(cheng)重(zhong)(zhong)(zhong)傳(chuan)(chuan)(chuan)(chuan)(chuan)感(gan)(gan)(gan)(gan)器(qi)(qi)的(de)(de)運(yun)用(yong)安全和壽數(shu)。稱(cheng)(cheng)(cheng)(cheng)重(zhong)(zhong)(zhong)傳(chuan)(chuan)(chuan)(chuan)(chuan)感(gan)(gan)(gan)(gan)器(qi)(qi)型式(shi)的(de)(de)選擇首要取決于(yu)(yu)稱(cheng)(cheng)(cheng)(cheng)量(liang)(liang)的(de)(de)類(lei)型和設備空間，確保設備適(shi)宜，稱(cheng)(cheng)(cheng)(cheng)量(liang)(liang)安全可(ke)靠(kao)；另一(yi)(yi)方面，要考慮(lv)稱(cheng)(cheng)(cheng)(cheng)重(zhong)(zhong)(zhong)傳(chuan)(chuan)(chuan)(chuan)(chuan)感(gan)(gan)(gan)(gan)器(qi)(qi)制造廠(chang)(chang)的(de)(de)建議。制造廠(chang)(chang)一(yi)(yi)般會(hui)根據(ju)稱(cheng)(cheng)(cheng)(cheng)重(zhong)(zhong)(zhong)傳(chuan)(chuan)(chuan)(chuan)(chuan)感(gan)(gan)(gan)(gan)器(qi)(qi)的(de)(de)受力情況、功用(yong)政策、設備方法(fa)、結構型式(shi)、彈性體的(de)(de)資料等(deng)(deng)特征規矩(ju)稱(cheng)(cheng)(cheng)(cheng)重(zhong)(zhong)(zhong)傳(chuan)(chuan)(chuan)(chuan)(chuan)感(gan)(gan)(gan)(gan)器(qi)(qi)的(de)(de)適(shi)用(yong)計劃(hua)，比如(ru)鋁式(shi)懸(xuan)臂(bei)梁稱(cheng)(cheng)(cheng)(cheng)重(zhong)(zhong)(zhong)傳(chuan)(chuan)(chuan)(chuan)(chuan)感(gan)(gan)(gan)(gan)器(qi)(qi)適(shi)用(yong)于(yu)(yu)計價秤(cheng)(cheng)、平臺秤(cheng)(cheng)、案秤(cheng)(cheng)等(deng)(deng)，鋼(gang)式(shi)懸(xuan)臂(bei)梁稱(cheng)(cheng)(cheng)(cheng)重(zhong)(zhong)(zhong)傳(chuan)(chuan)(chuan)(chuan)(chuan)感(gan)(gan)(gan)(gan)器(qi)(qi)適(shi)用(yong)于(yu)(yu)料斗秤(cheng)(cheng)、電子皮帶秤(cheng)(cheng)、分選秤(cheng)(cheng)等(deng)(deng)，鋼(gang)質橋式(shi)稱(cheng)(cheng)(cheng)(cheng)重(zhong)(zhong)(zhong)傳(chuan)(chuan)(chuan)(chuan)(chuan)感(gan)(gan)(gan)(gan)器(qi)(qi)適(shi)用(yong)于(yu)(yu)軌道衡(heng)、汽(qi)(qi)車(che)衡(heng)、天車(che)秤(cheng)(cheng)等(deng)(deng)，柱式(shi)稱(cheng)(cheng)(cheng)(cheng)重(zhong)(zhong)(zhong)傳(chuan)(chuan)(chuan)(chuan)(chuan)感(gan)(gan)(gan)(gan)器(qi)(qi)適(shi)用(yong)于(yu)(yu)汽(qi)(qi)車(che)衡(heng)、動態(tai)軌道衡(heng)、大(da)噸位料斗秤(cheng)(cheng)等(deng)(deng)。稱(cheng)(cheng)(cheng)(cheng)重(zhong)(zhong)(zhong)傳(chuan)(chuan)(chuan)(chuan)(chuan)感(gan)(gan)(gan)(gan)器(qi)(qi)

  2、稱(cheng)重傳感器的(de)準確度等級選擇

  稱重(zhong)(zhong)傳(chuan)(chuan)感(gan)(gan)(gan)器(qi)的(de)準(zhun)確度(du)(du)等級(ji)包(bao)括稱重(zhong)(zhong)傳(chuan)(chuan)感(gan)(gan)(gan)器(qi)的(de)非線(xian)性(xing)、蠕(ru)變、重(zhong)(zhong)復性(xing)、滯后、靈(ling)敏度(du)(du)等技術政(zheng)策(ce)。在選用的(de)時分不應當盲目尋(xun)求(qiu)高等級(ji)的(de)稱重(zhong)(zhong)傳(chuan)(chuan)感(gan)(gan)(gan)器(qi)，應當考慮電子衡的(de)準(zhun)確度(du)(du)等級(ji)和(he)本錢。一般情況下，選用稱重(zhong)(zhong)傳(chuan)(chuan)感(gan)(gan)(gan)器(qi)的(de)總精(jing)度(du)(du)為非線(xian)性(xing)、不重(zhong)(zhong)復性(xing)和(he)滯后三項(xiang)政(zheng)策(ce)的(de)之(zhi)和(he)的(de)均方根值略高于(yu)秤的(de)精(jing)度(du)(du)。稱重(zhong)(zhong)傳(chuan)(chuan)感(gan)(gan)(gan)器(qi)

  3、各(ge)種類型稱重傳感(gan)器的運用(yong)計劃

  選(xuan)(xuan)用的稱(cheng)重(zhong)傳(chuan)感(gan)器須滿足(zu)表面(mian)(mian)輸(shu)入靈敏度(du)的央求，須可以(yi)與(yu)所選(xuan)(xuan)表面(mian)(mian)匹配，滿足(zu)整臺(tai)電子秤準(zhun)確度(du)的央求。一(yi)臺(tai)電子秤首要(yao)是由(you)機械組織(zhi)、稱(cheng)重(zhong)傳(chuan)感(gan)器、表面(mian)(mian)三有些構成，在對稱(cheng)重(zhong)傳(chuan)感(gan)器準(zhun)確度(du)選(xuan)(xuan)擇的時分，應使稱(cheng)重(zhong)傳(chuan)感(gan)器的準(zhun)確度(du)略高于理論(lun)核算值，因為理論(lun)一(yi)般遭到(dao)客觀(guan)條(tiao)件(jian)的束縛，如機械結構的強(qiang)度(du)、表面(mian)(mian)的功用、秤的工作環(huan)境惡劣程(cheng)度(du)等要(yao)素(su)都(dou)直接影響到(dao)秤的準(zhun)確度(du)。因此要(yao)從各方(fang)面(mian)(mian)行進央求，統(tong)籌經濟效益，確保抵(di)達意(yi)圖。

  4、運用環境(jing)

  一般(ban)情況(kuang)下，高溫環(huan)境對(dui)稱(cheng)重傳(chuan)(chuan)感器(qi)(qi)構成涂覆資料融化、焊點開化、彈(dan)性(xing)(xing)體內應(ying)力發(fa)生(sheng)結構改動等(deng)疑問；粉塵、濕潤對(dui)稱(cheng)重傳(chuan)(chuan)感器(qi)(qi)構成短(duan)路的(de)(de)影響；在(zai)腐蝕(shi)性(xing)(xing)較高的(de)(de)環(huan)境下會構成稱(cheng)重傳(chuan)(chuan)感器(qi)(qi)彈(dan)性(xing)(xing)體受損或發(fa)生(sheng)短(duan)路表象；電磁場對(dui)稱(cheng)重傳(chuan)(chuan)感器(qi)(qi)輸出會發(fa)生(sheng)攪擾。相應(ying)的(de)(de)環(huan)境要素下咱們有必要選擇對(dui)應(ying)的(de)(de)稱(cheng)重傳(chuan)(chuan)感器(qi)(qi)才調滿足必要的(de)(de)稱(cheng)重央(yang)求。

  通過對稱重傳(chuan)(chuan)感(gan)器的(de)數量(liang)和量(liang)程原理的(de)了(le)解，相信大(da)家(jia)對稱重傳(chuan)(chuan)感(gan)器有了(le)一定(ding)的(de)了(le)解。
