Anti-interference wheel sensor

The utility model relates to an anti-interference wheel sensor. The utility model aims to provide a wheel sensor with simple structure which can counteract the interference of external electrical fields, improve the detecting accuracy of running parameter of railways trains, and guarantee the driving safety of trains. The anti-interference wheel sensor is composed of a casing, a magnetizing U-shaped iron, a first induction coil, a second induction coil, and water-proof insulation fillers. The parameter of the first induction coil is completely same to the parameter of the second induction coil. Both ends of the first induction coil and the second induction coil are respectively connected to synonymous ends. The first induction coil is sheathed on the outside end of the magnetizing U-shaped iron. The first induction coil, the second induction coil and the magnetizing U-shaped iron are arranged in the casing. The water-proof insulation fillers are filled in the inner interspace of the casing and an open end.
