干擾類型通常按干擾產(chǎn)生的原因、噪聲的干擾模式和噪聲的波形性質(zhì)的不同劃分。其中：按噪聲產(chǎn)生的原因不同，分為放電噪聲、浪涌噪聲、高頻振蕩噪聲等；按噪聲的波形、性質(zhì)不同，分為持續(xù)噪聲、偶發(fā)噪聲等；按聲音干擾模式不同，分為共模干擾和差模干擾。共模干擾和差模干擾是一種比較常用的分類方法。共模干擾是信號對地面的電位差，主要由電網(wǎng)串入、地電位差及空間電磁輻射在信號線上感應(yīng)的共態(tài)（同方向）電壓送加所形成。

共模電壓有時(shí)較大，特別是采用隔離性能差的電器供電室，變送器輸出信號的共模電壓普遍較高，有的可高達(dá)130V以上。共模電壓通過不對稱電路可轉(zhuǎn)換成差模電壓，直接影響測控信號，造成元器件損壞（這就是一些系統(tǒng)I/O模件損壞率較高的原因），這種共模干擾可為直流、亦可為交流。差模干擾是指用于信號兩極間得干擾電壓，主要由空間電磁場在信號間耦合感應(yīng)及由不平衡電路轉(zhuǎn)換共模干擾所形成的電壓，這種讓直接疊加在信號上，直接影響測量與控制精度。
