一般來說，傳感(gan)(gan)器(qi)的(de)(de)量程越接近分配到(dao)每個傳感(gan)(gan)器(qi)的(de)(de)載荷，其(qi)稱量的(de)(de)準確度就越高。但在實(shi)習運(yun)用(yong)時(shi)，因(yin)為加在傳感(gan)(gan)器(qi)上(shang)的(de)(de)載荷除被(bei)稱物體外，還存在秤體自重(zhong)(zhong)、皮重(zhong)(zhong)、偏載及振動沖擊(ji)等(deng)載荷，因(yin)此選用(yong)傳感(gan)(gan)器(qi)量程時(shi)，要(yao)考慮諸多方(fang)面(mian)的(de)(de)要(yao)素(su)，確保傳感(gan)(gan)器(qi)的(de)(de)安(an)全和(he)(he)壽數(shu)。今(jin)天說下稱重(zhong)(zhong)傳感(gan)(gan)器(qi)的(de)(de)數(shu)量和(he)(he)量程原(yuan)理(li)：

  1、稱(cheng)重(zhong)傳(chuan)感器的(de)數量(liang)和量(liang)程(cheng)

  一(yi)般(ban)應(ying)使(shi)稱(cheng)(cheng)(cheng)(cheng)重(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)傳感(gan)(gan)(gan)(gan)(gan)器(qi)(qi)(qi)在(zai)(zai)(zai)(zai)其(qi)30%～70%量程內工作。但對于(yu)一(yi)些在(zai)(zai)(zai)(zai)運(yun)用(yong)過(guo)程中存在(zai)(zai)(zai)(zai)較(jiao)大(da)沖擊力(li)的(de)衡(heng)器(qi)(qi)(qi)，如(ru)動態(tai)軌(gui)(gui)道(dao)衡(heng)、動態(tai)汽車衡(heng)、鋼(gang)材秤(cheng)等(deng)，在(zai)(zai)(zai)(zai)選(xuan)用(yong)稱(cheng)(cheng)(cheng)(cheng)重(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)傳感(gan)(gan)(gan)(gan)(gan)器(qi)(qi)(qi)時，一(yi)般(ban)要(yao)(yao)拓(tuo)展(zhan)其(qi)量程，使(shi)稱(cheng)(cheng)(cheng)(cheng)重(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)傳感(gan)(gan)(gan)(gan)(gan)器(qi)(qi)(qi)在(zai)(zai)(zai)(zai)其(qi)量程的(de)20%～30%以(yi)內工作，使(shi)稱(cheng)(cheng)(cheng)(cheng)重(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)傳感(gan)(gan)(gan)(gan)(gan)器(qi)(qi)(qi)的(de)稱(cheng)(cheng)(cheng)(cheng)量儲(chu)藏量程增大(da)，以(yi)確保(bao)稱(cheng)(cheng)(cheng)(cheng)重(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)傳感(gan)(gan)(gan)(gan)(gan)器(qi)(qi)(qi)的(de)運(yun)用(yong)安全和(he)壽(shou)數。稱(cheng)(cheng)(cheng)(cheng)重(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)傳感(gan)(gan)(gan)(gan)(gan)器(qi)(qi)(qi)型式(shi)(shi)(shi)的(de)選(xuan)擇首要(yao)(yao)取(qu)決于(yu)稱(cheng)(cheng)(cheng)(cheng)量的(de)類型和(he)設備空間，確保(bao)設備適(shi)宜(yi)，稱(cheng)(cheng)(cheng)(cheng)量安全可靠；另一(yi)方面，要(yao)(yao)考慮稱(cheng)(cheng)(cheng)(cheng)重(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)傳感(gan)(gan)(gan)(gan)(gan)器(qi)(qi)(qi)制(zhi)造(zao)廠(chang)的(de)建議。制(zhi)造(zao)廠(chang)一(yi)般(ban)會根據稱(cheng)(cheng)(cheng)(cheng)重(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)傳感(gan)(gan)(gan)(gan)(gan)器(qi)(qi)(qi)的(de)受力(li)情況、功(gong)用(yong)政(zheng)策、設備方法、結(jie)構型式(shi)(shi)(shi)、彈(dan)性體的(de)資(zi)料(liao)(liao)等(deng)特征規矩(ju)稱(cheng)(cheng)(cheng)(cheng)重(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)傳感(gan)(gan)(gan)(gan)(gan)器(qi)(qi)(qi)的(de)適(shi)用(yong)計劃，比如(ru)鋁(lv)式(shi)(shi)(shi)懸臂梁(liang)稱(cheng)(cheng)(cheng)(cheng)重(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)傳感(gan)(gan)(gan)(gan)(gan)器(qi)(qi)(qi)適(shi)用(yong)于(yu)計價秤(cheng)、平臺秤(cheng)、案(an)秤(cheng)等(deng)，鋼(gang)式(shi)(shi)(shi)懸臂梁(liang)稱(cheng)(cheng)(cheng)(cheng)重(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)傳感(gan)(gan)(gan)(gan)(gan)器(qi)(qi)(qi)適(shi)用(yong)于(yu)料(liao)(liao)斗(dou)秤(cheng)、電子皮帶秤(cheng)、分選(xuan)秤(cheng)等(deng)，鋼(gang)質橋式(shi)(shi)(shi)稱(cheng)(cheng)(cheng)(cheng)重(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)傳感(gan)(gan)(gan)(gan)(gan)器(qi)(qi)(qi)適(shi)用(yong)于(yu)軌(gui)(gui)道(dao)衡(heng)、汽車衡(heng)、天車秤(cheng)等(deng)，柱式(shi)(shi)(shi)稱(cheng)(cheng)(cheng)(cheng)重(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)傳感(gan)(gan)(gan)(gan)(gan)器(qi)(qi)(qi)適(shi)用(yong)于(yu)汽車衡(heng)、動態(tai)軌(gui)(gui)道(dao)衡(heng)、大(da)噸位料(liao)(liao)斗(dou)秤(cheng)等(deng)。稱(cheng)(cheng)(cheng)(cheng)重(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)傳感(gan)(gan)(gan)(gan)(gan)器(qi)(qi)(qi)

  2、稱重(zhong)傳感器(qi)的準確(que)度(du)等級選擇

  稱重(zhong)(zhong)傳感器的(de)準(zhun)確度等級包括稱重(zhong)(zhong)傳感器的(de)非線性(xing)(xing)、蠕變、重(zhong)(zhong)復性(xing)(xing)、滯后(hou)、靈敏度等技術(shu)政策。在選用(yong)的(de)時分不(bu)應當盲(mang)目尋求高等級的(de)稱重(zhong)(zhong)傳感器，應當考慮(lv)電子衡的(de)準(zhun)確度等級和(he)(he)本錢(qian)。一(yi)般情況下，選用(yong)稱重(zhong)(zhong)傳感器的(de)總(zong)精度為非線性(xing)(xing)、不(bu)重(zhong)(zhong)復性(xing)(xing)和(he)(he)滯后(hou)三項政策的(de)之(zhi)和(he)(he)的(de)均(jun)方(fang)根值略高于秤的(de)精度。稱重(zhong)(zhong)傳感器

  3、各種類型稱重傳感(gan)器(qi)的運用計劃

  選用的(de)(de)稱(cheng)重(zhong)(zhong)(zhong)傳感(gan)器(qi)(qi)(qi)須(xu)滿足表(biao)(biao)面輸(shu)入靈敏(min)度的(de)(de)央(yang)求(qiu)(qiu)，須(xu)可以與(yu)所選表(biao)(biao)面匹配(pei)，滿足整臺電子秤準(zhun)確(que)度的(de)(de)央(yang)求(qiu)(qiu)。一(yi)臺電子秤首要(yao)(yao)是由機械組織、稱(cheng)重(zhong)(zhong)(zhong)傳感(gan)器(qi)(qi)(qi)、表(biao)(biao)面三有些構成，在(zai)對稱(cheng)重(zhong)(zhong)(zhong)傳感(gan)器(qi)(qi)(qi)準(zhun)確(que)度選擇的(de)(de)時分，應使稱(cheng)重(zhong)(zhong)(zhong)傳感(gan)器(qi)(qi)(qi)的(de)(de)準(zhun)確(que)度略高于理論(lun)核算值，因(yin)為理論(lun)一(yi)般遭到(dao)客觀條件的(de)(de)束(shu)縛，如機械結構的(de)(de)強度、表(biao)(biao)面的(de)(de)功用、秤的(de)(de)工作(zuo)環境惡劣程(cheng)度等(deng)要(yao)(yao)素都直接影響到(dao)秤的(de)(de)準(zhun)確(que)度。因(yin)此要(yao)(yao)從(cong)各方面行(xing)進(jin)央(yang)求(qiu)(qiu)，統籌經濟效(xiao)益，確(que)保抵達意圖(tu)。

  4、運用環境

  一般情況下(xia)，高(gao)溫環境對(dui)稱重(zhong)傳(chuan)感器(qi)(qi)構成(cheng)涂覆資料(liao)融化、焊(han)點開化、彈性體內應(ying)力發生結(jie)構改動等疑問；粉塵、濕潤對(dui)稱重(zhong)傳(chuan)感器(qi)(qi)構成(cheng)短(duan)路的(de)(de)影響；在腐蝕性較高(gao)的(de)(de)環境下(xia)會構成(cheng)稱重(zhong)傳(chuan)感器(qi)(qi)彈性體受損(sun)或發生短(duan)路表象；電磁(ci)場對(dui)稱重(zhong)傳(chuan)感器(qi)(qi)輸出(chu)會發生攪擾。相應(ying)的(de)(de)環境要(yao)(yao)素下(xia)咱(zan)們有必(bi)要(yao)(yao)選擇對(dui)應(ying)的(de)(de)稱重(zhong)傳(chuan)感器(qi)(qi)才調(diao)滿足必(bi)要(yao)(yao)的(de)(de)稱重(zhong)央求。

  通過對(dui)稱重(zhong)傳感器的(de)數量和量程原理(li)的(de)了解(jie)(jie)，相信(xin)大家對(dui)稱重(zhong)傳感器有了一定的(de)了解(jie)(jie)。
