摘要
The pulse emitter produces pulses which are dependent on the movement of ferromagnetic parts (5), in the magnetic field of a magnet (1). A partition wall (4) is located between the magnet and a magnetic sensor (2). The distance (D1) between the ferromagnetic parts and magnet is smaller than the distance (D2) between the magnet and the magnetic sensor. The teeth of the gear wheel (3) rotate in a non-ferromagnetic housing, themselves acting as the ferromagnetic parts. The magnet is fixed at the inner wall and the magnetic sensor is fixed at the outer wall of the housing.
