style="text-indent:25px">電流傳感器的優(yōu)點(diǎn)和缺點(diǎn)：由于基本操作元件（纏繞線圈和金屬部件）的性質(zhì)，大多數(shù)感應(yīng)式位置傳感器非常堅(jiān)固。鑒于其良好的聲譽(yù)，一個(gè)顯而易見(jiàn)的問(wèn)題是“為什么電流傳感器不能更頻繁地使用？” 原因是他們的身體健壯性既是力量也是弱點(diǎn)。電流傳感器往往精確，可靠，堅(jiān)固，但體積大，體積大，重量大。對(duì)精密纏繞線圈的需求也使其生產(chǎn)成本高昂 - 尤其是高精度設(shè)備。除了簡(jiǎn)單的接近傳感器之外，更復(fù)雜的電流傳感器對(duì)于更主流的應(yīng)用來(lái)說(shuō)非常昂貴。</p><p
