The utility model discloses a length sensor with the adjustment of a measurement length, belonging to the technical field of measuring devices. A gear mounting plate (14) is fixedly connected to a base (10) through a fastening piece. A drum (8) is arranged between the gear mounting plate (14) and the base (10) and is fixed on a shaft I. One end of the shaft I is connected to the base (10), and the other end passes through the gear mounting plate (14). A driving gear (6) is engaged with a transmission gear (B). A transmission gear A (2) is engaged with a transmission gear A (3). A transmission gear B (16) is engaged with the full gear in a trigger gear (4). A detection switch (5) is arranged on the gear mounting plate (14) close to the trigger gear (4). A pull rope (7) is wound on the drum (8). The output length can be adjusted according to needs, the maintainability is strong, the measurement precision is ensured in a high magnetic field environment, a switch quantity signal is outputted, an additional processor is not needed, and the cost is reduced.
