【 摘 要 】

Inductance sensor is widely applied in engineering survey. The operation principle of the inductance sensor has analyzed in this paper, the output characteristic function of the inductance sensor obtained by comparing the change relationship which coil inductance value displace with magnetic core when inductance sensor working. The simulation software has used to analyze an inductance sensor, and experiment has been taken to poof that, out linearity of the sensor is better within a certain measuring range, it is less than 0.8% in the 2mm working range, with the measuring range increases, the linearity of the inductance sensor become worse, and then affect the measurement accuracy. this research provides a basis for how to select the appropriate working range when using inductance sensors.
