動(dong)--靜(jing)(jing)環(huan)之間(jian)只有零點(dian)幾毫米的(de)(de)(de)(de)間(jian)隙，加之傳(chuan)(chuan)(chuan)感(gan)(gan)器(qi)軸(zhou)上(shang)部(bu)分(fen)都密(mi)封在金屬(shu)外殼之內，形成(cheng)(cheng)有效(xiao)(xiao)的(de)(de)(de)(de)屏(ping)蔽，因此具有很強(qiang)的(de)(de)(de)(de)抗干(gan)擾能力。有些傳(chuan)(chuan)(chuan)感(gan)(gan)器(qi)既(ji)不(bu)能劃分(fen)到物(wu)理(li)(li)(li)
