电涡流位移传感器可以作为电控柴油机油泵齿杆位移传感器，对其进行标定是实际应用中面临的重要问题。文中叙述了一种较为可行的标定方法，其标定的基本原理为：线圈的等效电感 L和被测物体与传感器线圈的距离 x存在一定的函数关系，利用这种函数关系用调频法进行测量，标定系统由测量电路、高稳定度稳压电源、数字频率计、被测导体及被校位移传感器组成。标定结果表明此种方法是可行且有效的。 Eddy current displacement sensor can be used as an electronic diesel gear pump displacement sensor, its calibration is an important issue in practical applications. This paper describes a more feasible calibration method, the calibration of the basic principle is: the equivalent inductance of the coil L and the measured object and the sensor coil distance x there is a certain relationship between the use of this function to measure the frequency modulation method , Calibration system consists of measuring circuit, high stability power supply, digital frequency meter, the measured conductor and the school displacement sensor. Calibration results show that this method is feasible and effective.
