The invention relates to inductance frequency modulation intelligent digital shift sensor, which includes sealed shell and a inductance coil in the shell, moving pole and data processing circuit, the data processing circuit includes capacitance, timer, microchip, series memory chip, series interface chip; the moving pole is inserted into the inductance coil, which is a magnetic inducting metal pole which can move in the coil relatively, the inductance coil is a metal coil whose inductance quantity L changes with the movement of the moving pole, the two ends are connected to the data processing circuit. The merits of the invention are: the measuring result has nothing to do with the cable length, the precision is high, the stability is excellent, it can be applied to long distance transmission; it can output shift quantity directly, displays the number of sensor, technology parameter and the measuring environment parameter; the number of sensor and the labeled parameter and so on records are memorized in the memory chip, and it can save 250 times of measured parameter in each measurement.
