磁致伸縮液位計(jì)選材妙招

  說起磁致伸縮液位計(jì)的選料方面大致有這幾個(gè)方面和相關(guān)要素和基礎(chǔ)選料磁致伸縮液位計(jì)的時(shí)候選料原則為:
  [1]磁致伸縮液位計(jì)資料應(yīng)具有明顯的磁致彈性效應(yīng),變個(gè)說法,其磁致彈性應(yīng)力常數(shù)和應(yīng)變常數(shù),還有就是機(jī)電耦合系數(shù)要越大越好;
  [2]磁致伸縮液位計(jì)渦流損耗和磁滯扔掉要越小越好,這也意味著資料的電阻率應(yīng)當(dāng)較高或者說電導(dǎo)率較低為好;
  [3]磁致伸縮液位計(jì)機(jī)械強(qiáng)度要高,大功率運(yùn)用時(shí)的振蕩振幅度肯定比較大;
  [4]磁致伸縮液位計(jì)時(shí)刻穩(wěn)定性好,不是特容易老化,以保證運(yùn)用壽命;
  [5]磁致伸縮液位計(jì)居里溫度較高,以保證其溫度穩(wěn)定性好,當(dāng)然磁致彈性換能器在運(yùn)用過程中是必定要發(fā)熱的;
  [6]要從實(shí)習(xí)運(yùn)用需求啟航,運(yùn)用效果與經(jīng)濟(jì)效益需歸納思考,如資料報(bào)價(jià)、制造本錢等。
