style="text-indent:25px">拉繩位移傳感器的晶體管的噪聲：晶體管的噪聲主要有熱噪聲、散粒噪聲、閃爍噪聲。熱噪聲是由于載流子不規(guī)則的熱運(yùn)動(dòng)通過(guò)BJT內(nèi)3個(gè)區(qū)的體電阻及相應(yīng)的引線(xiàn)電阻時(shí)而產(chǎn)生。其中所產(chǎn)生的噪聲是主要的。通常所說(shuō)的BJT中的電流，只是一個(gè)平均值。實(shí)際上通過(guò)發(fā)射結(jié)注入到基區(qū)的載流子數(shù)目，在各個(gè)瞬時(shí)都不相同，因而發(fā)射極電流或集電極電流都有無(wú)規(guī)則的波動(dòng)，會(huì)產(chǎn)生散粒噪聲。由于半導(dǎo)體材料及制造工藝水平使得晶體管表面清潔處理不好而引起的噪聲稱(chēng)為閃爍噪聲。它與半導(dǎo)體表面少數(shù)載流子的復(fù)合有關(guān)，表現(xiàn)為發(fā)射極電流的起伏，其電流噪聲譜密度與頻率近似成反比，又稱(chēng)1/f噪聲。它主要在低頻(kHz以下)范圍起主要作用。</p><p style="text-indent:25px">拉線(xiàn)位移傳感器的常見(jiàn)故障及排障方法：1.要證明看是否是靜電干擾時(shí)，可以先使用一段電源線(xiàn)把電子尺的封蓋螺絲跟機(jī)器上的某一些的金屬短接起來(lái)就可以了，只要一短接起來(lái)，靜電干擾就會(huì)馬上解決掉的。但是如果要解決掉高頻干擾就很難用上面的方法了，變頻節(jié)電器和機(jī)器手都經(jīng)常出現(xiàn)高頻干擾的，所以可以試一下用停止高頻節(jié)電器或者機(jī)械手的方法來(lái)驗(yàn)證是不是高頻干擾的。2.供電的電壓一定要穩(wěn)定，工業(yè)的電壓需要符合±0.1[%]的穩(wěn)定性，例如，基準(zhǔn)電壓是10V的話(huà)，就可以允許有±0.01V的波動(dòng)變化，如果不是的話(huà)，就會(huì)引起顯示的圈套波動(dòng)這樣的情況。但是如果這個(gè)時(shí)候的顯示波動(dòng)的幅度沒(méi)有超過(guò)波動(dòng)電壓的波動(dòng)的幅度的話(huà)，那么電子尺就是正常的了。拉繩位移傳感器的尺寸、緊湊性和重量都是選擇時(shí)需要考慮的重要因素。</p><div
