眾所周知，導波雷達物位計的優點非常明顯，比如它測量精度高，易維護，可以滿足高溫、高壓、蒸汽、真(zhen)空、高粉塵等(deng)惡(e)劣(lie)環(huan)境的(de)要求，在越來越多的(de)行業中廣泛被(bei)(bei)應用。但是再好(hao)的(de)東西，也(ye)會(hui)有一些問(wen)題，比(bi)如會(hui)出現(xian)故障(zhang)，那么怎么去判(pan)斷故障(zhang)是一個(ge)值得被(bei)(bei)探討的(de)問(wen)題，只有發(fa)現(xian)問(wen)題，才能解決問(wen)題，從而達(da)到最有效(xiao)果。下面給大家總(zong)結(jie)了幾(ji)種，最基本的(de)判(pan)斷導波雷達(da)物位(wei)計故障(zhang)的(de)方(fang)法。

首先是(shi)目視檢查方法(fa)，就是(shi)不使用(yong)任何測(ce)(ce)(ce)試(shi)儀(yi)器(qi)，而是(shi)通過人的(de)感官(guan)觀察來發現(xian)故(gu)障。第(di)(di)二種是(shi)斷(duan)(duan)路(lu)法(fa)，將(jiang)我們(men)所認為(wei)的(de)可疑部(bu)位從整機上(shang)斷(duan)(duan)開(kai)，看故(gu)障是(shi)否(fou)(fou)能消失，以確(que)定故(gu)障。第(di)(di)三種是(shi)更換方法(fa)，通過更換一些部(bu)件或(huo)(huo)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)路(lu)板，確(que)定故(gu)障在(zai)某個(ge)位置。第(di)(di)四(si)種是(shi)阻(zu)(zu)法(fa)，電(dian)(dian)(dian)(dian)(dian)(dian)(dian)阻(zu)(zu)檢查法(fa)是(shi)在(zai)無(wu)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)的(de)情況下，用(yong)萬用(yong)表(biao)的(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)阻(zu)(zu)塊檢查儀(yi)表(biao)的(de)整條(tiao)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)路(lu)和(he)部(bu)分電(dian)(dian)(dian)(dian)(dian)(dian)(dian)路(lu)的(de)輸(shu)入、輸(shu)出電(dian)(dian)(dian)(dian)(dian)(dian)(dian)阻(zu)(zu)是(shi)否(fou)(fou)正(zheng)常(chang)，電(dian)(dian)(dian)(dian)(dian)(dian)(dian)容器(qi)是(shi)否(fou)(fou)損壞或(huo)(huo)泄漏，電(dian)(dian)(dian)(dian)(dian)(dian)(dian)感線圈和(he)變壓器(qi)是(shi)否(fou)(fou)斷(duan)(duan)開(kai)或(huo)(huo)短(duan)路(lu)。最后一種是(shi)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)流法(fa)，電(dian)(dian)(dian)(dian)(dian)(dian)(dian)流法(fa)分為(wei)直接(jie)測(ce)(ce)(ce)量(liang)和(he)間(jian)接(jie)測(ce)(ce)(ce)量(liang)。直接(jie)測(ce)(ce)(ce)量(liang)是(shi)將(jiang)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)路(lu)斷(duan)(duan)開(kai)后連接(jie)到電(dian)(dian)(dian)(dian)(dian)(dian)(dian)流表(biao)上(shang)，將(jiang)測(ce)(ce)(ce)量(liang)的(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)流值與儀(yi)表(biao)正(zheng)常(chang)狀態(tai)下的(de)值進行比較，以判(pan)斷(duan)(duan)故(gu)障。間(jian)接(jie)測(ce)(ce)(ce)量(liang)不用(yong)斷(duan)(duan)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)，測(ce)(ce)(ce)量(liang)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)阻(zu)(zu)上(shang)的(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓降，并根據電(dian)(dian)(dian)(dian)(dian)(dian)(dian)阻(zu)(zu)值計算近似電(dian)(dian)(dian)(dian)(dian)(dian)(dian)流值。

以上這(zhe)幾種辦法(fa)都(dou)不(bu)復雜，屬(shu)于(yu)比(bi)較簡單的操作(zuo)，但是也需(xu)要(yao)技術維護人員具備(bei)一定的專業(ye)知識，并且耐心，細心才可以達(da)到理(li)想效果。
