干擾類型通常按干擾產生的原因、噪聲的干擾模式和噪聲的波形性質的不同劃分。其中：按噪聲產生的原因不同，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，主要由電網串入、地電位差及空間電磁輻射在信號線上感應的共態(tài)（同方向）電壓送加所形成。

共模電壓有時較大，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130V以上。共模電壓通過不對稱電路可轉換成差模電壓，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及由不平衡電路轉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。
