干扰类型通常按干扰产生的原因、噪声的干扰模式和噪声的波形性质的不同划分。其中：按噪声产生的原因不同，分为放电噪声、浪涌噪声、高频振荡噪声等；按噪声的波形、性质不同控制工程网版权所有，分为持续噪声、偶发噪声等；按声音干扰模式不同，分为共模干扰和差模干扰。共模干扰和差模干扰是一种比较常用的分类方法。共模干扰是信号对地面的电位差，主要由电网串入、地电位差及空间电磁辐射在信号线上感应的共态（同方向）电压送加所形成。共模电压有时较大，特别是采用隔离性能差的电器供电室，变送器输出信号的共模电压普遍较高，有的可高达130V以上。共模电压通过不对称电路可转换成差模电压，直接影响测控信号，造成元器件损坏（这就是一些系统I/O模件损坏率较高的原因），这种共模干扰可为直流、亦可为交流。差模干扰是指用于信号两极间得干扰电压，主要由空间电磁场在信号间耦合感应及由不平衡电路转换共模干扰所形成的电压，这种让直接叠加在信号上，直接影响测量与控制精度。
