The utility model discloses a built-in magnetic induction displacement sensor, which comprises a sensor body, an induction strip and a displacement induction part, the displacement induction part is used for converting linear mechanical displacement into electric signals, the induction strip is electrically connected with the sensor body, and the displacement induction part is arranged outside the induction strip. The displacement sensing part can move along the sensing strip; and a strong magnetic block is arranged in the displacement sensing part. The sensor provided by the utility model can be matched with a traditional settlement pipe and a settlement magnetic ring for use, has strong applicability, can directly and automatically monitor the settlement amount of a rock stratum or a soil layer when the rock stratum or the soil layer settles, does not need manual repeated measurement through a measuring head, can directly and timely feed back the settlement amount, can eliminate errors existing in manual me
