一般來說，傳(chuan)感(gan)(gan)器的(de)量程(cheng)(cheng)越接近分配到每個傳(chuan)感(gan)(gan)器的(de)載(zai)荷(he)(he)，其稱量的(de)準確度就越高。但在(zai)實習運用時(shi)，因為加在(zai)傳(chuan)感(gan)(gan)器上(shang)的(de)載(zai)荷(he)(he)除被稱物體外，還(huan)存在(zai)秤(cheng)體自重、皮重、偏(pian)載(zai)及振動(dong)沖擊(ji)等載(zai)荷(he)(he)，因此選(xuan)用傳(chuan)感(gan)(gan)器量程(cheng)(cheng)時(shi)，要(yao)考慮諸(zhu)多(duo)方面的(de)要(yao)素，確保傳(chuan)感(gan)(gan)器的(de)安全(quan)和(he)壽數。今(jin)天說下(xia)稱重傳(chuan)感(gan)(gan)器的(de)數量和(he)量程(cheng)(cheng)原理：

  1、稱重傳感器的數量(liang)和量(liang)程

  一般應(ying)使稱(cheng)(cheng)(cheng)(cheng)(cheng)重(zhong)(zhong)(zhong)(zhong)傳(chuan)(chuan)(chuan)(chuan)(chuan)感(gan)(gan)(gan)(gan)(gan)器(qi)(qi)在(zai)其30%～70%量(liang)程(cheng)(cheng)(cheng)(cheng)內(nei)工作。但對于(yu)(yu)一些在(zai)運用(yong)(yong)過程(cheng)(cheng)(cheng)(cheng)中存在(zai)較大(da)沖擊力的(de)(de)衡(heng)器(qi)(qi)，如(ru)動態(tai)軌(gui)道(dao)衡(heng)、動態(tai)汽(qi)車(che)(che)衡(heng)、鋼材(cai)秤(cheng)(cheng)(cheng)等，在(zai)選用(yong)(yong)稱(cheng)(cheng)(cheng)(cheng)(cheng)重(zhong)(zhong)(zhong)(zhong)傳(chuan)(chuan)(chuan)(chuan)(chuan)感(gan)(gan)(gan)(gan)(gan)器(qi)(qi)時(shi)，一般要拓(tuo)展其量(liang)程(cheng)(cheng)(cheng)(cheng)，使稱(cheng)(cheng)(cheng)(cheng)(cheng)重(zhong)(zhong)(zhong)(zhong)傳(chuan)(chuan)(chuan)(chuan)(chuan)感(gan)(gan)(gan)(gan)(gan)器(qi)(qi)在(zai)其量(liang)程(cheng)(cheng)(cheng)(cheng)的(de)(de)20%～30%以內(nei)工作，使稱(cheng)(cheng)(cheng)(cheng)(cheng)重(zhong)(zhong)(zhong)(zhong)傳(chuan)(chuan)(chuan)(chuan)(chuan)感(gan)(gan)(gan)(gan)(gan)器(qi)(qi)的(de)(de)稱(cheng)(cheng)(cheng)(cheng)(cheng)量(liang)儲藏量(liang)程(cheng)(cheng)(cheng)(cheng)增大(da)，以確保(bao)稱(cheng)(cheng)(cheng)(cheng)(cheng)重(zhong)(zhong)(zhong)(zhong)傳(chuan)(chuan)(chuan)(chuan)(chuan)感(gan)(gan)(gan)(gan)(gan)器(qi)(qi)的(de)(de)運用(yong)(yong)安全和壽數。稱(cheng)(cheng)(cheng)(cheng)(cheng)重(zhong)(zhong)(zhong)(zhong)傳(chuan)(chuan)(chuan)(chuan)(chuan)感(gan)(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)(cheng)量(liang)的(de)(de)類型和設備空間，確保(bao)設備適宜，稱(cheng)(cheng)(cheng)(cheng)(cheng)量(liang)安全可靠(kao)；另一方面(mian)，要考慮稱(cheng)(cheng)(cheng)(cheng)(cheng)重(zhong)(zhong)(zhong)(zhong)傳(chuan)(chuan)(chuan)(chuan)(chuan)感(gan)(gan)(gan)(gan)(gan)器(qi)(qi)制造(zao)廠的(de)(de)建議。制造(zao)廠一般會(hui)根據(ju)稱(cheng)(cheng)(cheng)(cheng)(cheng)重(zhong)(zhong)(zhong)(zhong)傳(chuan)(chuan)(chuan)(chuan)(chuan)感(gan)(gan)(gan)(gan)(gan)器(qi)(qi)的(de)(de)受力情況、功用(yong)(yong)政策、設備方法、結構型式(shi)、彈性體的(de)(de)資(zi)料(liao)等特征(zheng)規矩稱(cheng)(cheng)(cheng)(cheng)(cheng)重(zhong)(zhong)(zhong)(zhong)傳(chuan)(chuan)(chuan)(chuan)(chuan)感(gan)(gan)(gan)(gan)(gan)器(qi)(qi)的(de)(de)適用(yong)(yong)計劃，比如(ru)鋁式(shi)懸(xuan)臂梁(liang)稱(cheng)(cheng)(cheng)(cheng)(cheng)重(zhong)(zhong)(zhong)(zhong)傳(chuan)(chuan)(chuan)(chuan)(chuan)感(gan)(gan)(gan)(gan)(gan)器(qi)(qi)適用(yong)(yong)于(yu)(yu)計價秤(cheng)(cheng)(cheng)、平臺(tai)秤(cheng)(cheng)(cheng)、案秤(cheng)(cheng)(cheng)等，鋼式(shi)懸(xuan)臂梁(liang)稱(cheng)(cheng)(cheng)(cheng)(cheng)重(zhong)(zhong)(zhong)(zhong)傳(chuan)(chuan)(chuan)(chuan)(chuan)感(gan)(gan)(gan)(gan)(gan)器(qi)(qi)適用(yong)(yong)于(yu)(yu)料(liao)斗秤(cheng)(cheng)(cheng)、電子皮(pi)帶秤(cheng)(cheng)(cheng)、分選秤(cheng)(cheng)(cheng)等，鋼質橋式(shi)稱(cheng)(cheng)(cheng)(cheng)(cheng)重(zhong)(zhong)(zhong)(zhong)傳(chuan)(chuan)(chuan)(chuan)(chuan)感(gan)(gan)(gan)(gan)(gan)器(qi)(qi)適用(yong)(yong)于(yu)(yu)軌(gui)道(dao)衡(heng)、汽(qi)車(che)(che)衡(heng)、天車(che)(che)秤(cheng)(cheng)(cheng)等，柱(zhu)式(shi)稱(cheng)(cheng)(cheng)(cheng)(cheng)重(zhong)(zhong)(zhong)(zhong)傳(chuan)(chuan)(chuan)(chuan)(chuan)感(gan)(gan)(gan)(gan)(gan)器(qi)(qi)適用(yong)(yong)于(yu)(yu)汽(qi)車(che)(che)衡(heng)、動態(tai)軌(gui)道(dao)衡(heng)、大(da)噸位料(liao)斗秤(cheng)(cheng)(cheng)等。稱(cheng)(cheng)(cheng)(cheng)(cheng)重(zhong)(zhong)(zhong)(zhong)傳(chuan)(chuan)(chuan)(chuan)(chuan)感(gan)(gan)(gan)(gan)(gan)器(qi)(qi)

  2、稱重傳(chuan)感(gan)器的準確度(du)等級選擇

  稱(cheng)重傳感(gan)(gan)器(qi)的(de)準確度等(deng)(deng)級包(bao)括稱(cheng)重傳感(gan)(gan)器(qi)的(de)非線(xian)性(xing)、蠕變、重復性(xing)、滯后、靈敏度等(deng)(deng)技術政策。在選用(yong)的(de)時分不應(ying)(ying)當盲目(mu)尋求高(gao)(gao)等(deng)(deng)級的(de)稱(cheng)重傳感(gan)(gan)器(qi)，應(ying)(ying)當考慮電子衡的(de)準確度等(deng)(deng)級和本(ben)錢(qian)。一(yi)般情況下，選用(yong)稱(cheng)重傳感(gan)(gan)器(qi)的(de)總精(jing)度為非線(xian)性(xing)、不重復性(xing)和滯后三項(xiang)政策的(de)之和的(de)均方根值略高(gao)(gao)于秤的(de)精(jing)度。稱(cheng)重傳感(gan)(gan)器(qi)

  3、各(ge)種類型稱重傳感器的運用計劃

  選(xuan)用的(de)(de)稱(cheng)重(zhong)(zhong)(zhong)(zhong)傳(chuan)感(gan)器須滿足(zu)表面(mian)輸入靈(ling)敏度的(de)(de)央求，須可以與所選(xuan)表面(mian)匹配，滿足(zu)整(zheng)臺電子秤(cheng)(cheng)準確(que)(que)度的(de)(de)央求。一臺電子秤(cheng)(cheng)首要是(shi)由機械(xie)組織(zhi)、稱(cheng)重(zhong)(zhong)(zhong)(zhong)傳(chuan)感(gan)器、表面(mian)三有(you)些構(gou)(gou)成，在對稱(cheng)重(zhong)(zhong)(zhong)(zhong)傳(chuan)感(gan)器準確(que)(que)度選(xuan)擇的(de)(de)時分(fen)，應使稱(cheng)重(zhong)(zhong)(zhong)(zhong)傳(chuan)感(gan)器的(de)(de)準確(que)(que)度略高于理論(lun)核算值(zhi)，因為(wei)理論(lun)一般遭到客(ke)觀條(tiao)件的(de)(de)束縛(fu)，如機械(xie)結(jie)構(gou)(gou)的(de)(de)強度、表面(mian)的(de)(de)功(gong)用、秤(cheng)(cheng)的(de)(de)工(gong)作環境惡劣(lie)程度等要素(su)都直接影響到秤(cheng)(cheng)的(de)(de)準確(que)(que)度。因此要從(cong)各方面(mian)行進央求，統籌經濟效益，確(que)(que)保抵達意圖。

  4、運(yun)用環境

  一般情(qing)況下(xia)(xia)，高溫環(huan)境(jing)對(dui)稱(cheng)(cheng)重(zhong)(zhong)傳感(gan)器(qi)構(gou)成涂覆資料(liao)融化(hua)、焊(han)點開化(hua)、彈(dan)性體(ti)內(nei)應(ying)力發(fa)生(sheng)(sheng)結構(gou)改動等疑問；粉(fen)塵、濕潤對(dui)稱(cheng)(cheng)重(zhong)(zhong)傳感(gan)器(qi)構(gou)成短路(lu)的(de)影響；在腐(fu)蝕性較高的(de)環(huan)境(jing)下(xia)(xia)會構(gou)成稱(cheng)(cheng)重(zhong)(zhong)傳感(gan)器(qi)彈(dan)性體(ti)受損或發(fa)生(sheng)(sheng)短路(lu)表象(xiang)；電磁場對(dui)稱(cheng)(cheng)重(zhong)(zhong)傳感(gan)器(qi)輸出(chu)會發(fa)生(sheng)(sheng)攪擾。相應(ying)的(de)環(huan)境(jing)要素(su)下(xia)(xia)咱們有必要選擇對(dui)應(ying)的(de)稱(cheng)(cheng)重(zhong)(zhong)傳感(gan)器(qi)才調(diao)滿足(zu)必要的(de)稱(cheng)(cheng)重(zhong)(zhong)央求。

  通過對稱重傳(chuan)感器的數量和量程原理(li)的了(le)解，相信大家(jia)對稱重傳(chuan)感器有了(le)一定的了(le)解。
