二线制：在热电阻的两端各连接根导线来引出电阻信号的方式叫二线制：这种引线方法很简单，但由于连接导线必然存在引线电阻r，r大小与导线的材质和长度的因素有关，因此这种引线方式只适用于测量精度较低的场合 　　○2三线制：在热电阻的根部的端连接根引线，另端连接两根引线的方式称为三线制，这种方式通常与电桥配套使用，可以较好的消除引线电阻的影响，是工业过程控制中的zui常用的[1]。 　　○3四线制：在热电阻的根部两端各连接两根导线的方式称为四线制，其中两根引线为热电阻提供恒定电流I，把R转换成电压信号U，再通过另两根引线把U引二次仪表。可见这种引线方式可*消除引线的电阻影响，主要用于高精度的温度检测。 　　热电阻采用三线制接法。采用三线制是为了消除连接导线电阻引起的测量误差。这是因为测量热电阻的电路般是不平衡电桥。热电阻作为电桥的个桥臂电阻，其连接导线（从热电阻到中控室）也成为桥臂电阻的部分，这部分电阻是未知的 　　且随环境温度变化，造成测量误差。采用三线制，将导线根接到电桥的电源端，其余两根分别接到热电阻所在的桥臂及与其相邻的桥臂上，这样消除了导线线路电阻带来的测量误差
