style="text-indent:25px">這個時候，你可能認為好的電子尺難以一時判別，主要是難以確認，需要客戶長時間的實驗。那我們可以先判別一下差的電子尺，有幾個簡單的標準可以判別：電刷接觸碳膜面是否是光滑的？不管電刷是采用什么材料，鉑金也好、鈀金也好、就是黃金也好，我們無法知道，我們也不指望以后會回收。關(guān)鍵是看電刷與碳膜的接觸面是否光滑，是否會對碳膜造成傷害。用手指感覺一下即可，好的電子尺，電刷的接觸面是非常光潔的，不會對碳板造成傷害，能夠達到幾千萬次的壽命，同時碳板仍然保持很好的線性精度。而與碳板表面接觸面像鋼刷子一樣的電刷，對碳膜的傷害非常大，每運行一次都對碳板表面的碳膜刮掉一點，所以電子尺的數(shù)值是不斷變化的，所以，我們經(jīng)常遇到這樣的電子尺，在注塑過程中經(jīng)常不穩(wěn)定，需要經(jīng)常調(diào)整參數(shù)才能更正。這樣的電刷號稱幾千萬次，實際上，運行幾萬次時，電子尺的線性精度就面目全非了，以后的幾十萬次上百萬次，注塑機的性能已經(jīng)被極大地打了折扣，這實際上就是一個劣質(zhì)產(chǎn)品。</p><p style="text-indent:25px">拉線位移傳感器的低頻噪聲：低頻噪聲主要是由于內(nèi)部的導(dǎo)電微粒不連續(xù)造成的。特別是碳膜電阻，其碳質(zhì)材料內(nèi)部存在許多微小顆粒，顆粒之間是不連續(xù)的，在電流流過時，會使電阻的導(dǎo)電率發(fā)生變化引起電流的變化，產(chǎn)生類似接觸不良的閃爆電弧。另外，晶體管也可能產(chǎn)生相似的爆裂噪聲和閃爍噪聲，其產(chǎn)生機理與電阻中微粒的不連續(xù)性相近，也與晶體管的摻雜程度有關(guān)。拉線位移傳感器的半導(dǎo)體器件產(chǎn)生的散粒噪聲：由于半導(dǎo)體PN結(jié)兩端勢壘區(qū)電壓的變化引起累積在此區(qū)域的電荷數(shù)量改變，從而顯現(xiàn)出電容效應(yīng)。當外加正向電壓升高時，N區(qū)的電子和P區(qū)的空穴向耗盡區(qū)運動，相當于對電容充電。當正向電壓減小時，它又使電子和空穴遠離耗盡區(qū)，相當于電容放電。當外加反向電壓時，耗盡區(qū)的變化相反。當電流流經(jīng)勢壘區(qū)時，這種變化會引起流過勢壘區(qū)的電流產(chǎn)生微小波動，從而產(chǎn)生電流噪聲。其產(chǎn)生噪聲的大小與溫度、頻帶寬度△f成正比。直線位移傳感器(電子尺)的選擇方法標準。</p><div
