The foundation of information technology includes information collection, information transmission and information processing, and information collection cannot ignore the sensor technology. In recent years, the sensor is in the stage of development from traditional to new. Magnetic resistance sensor as a kind of new type of sensor, the research of it is becoming more and more important. This paper started with the basic concept of magnetic resistance sensor, and discussed the inductive, transformer and the eddy current type of the sensor's working principle, output characteristics, measurement circuit and the actual application in the life. Using sensors aimed at helping us improve life, also to promote social progress.Keywords:Magnetic Resistance Sensor; Inductive; Transformer; Eddy Current Type; Working Principle Application1.自感式电感传感器1.1自感式电感传感器定义自感式电感传感器,利用被测量的变化引起线圈自感或互感系数的变化,从而导致线圈电感量改变这一物理现象来实现测量的传感器。
