Inductive passive sensors Signal processing Wheel speed sensors are installed directly above the pulse wheel, which is connected to the wheel hub or the drive shaft. The pole pin inside a coil is connected to a permanent magnet and the magnetic field extends to the pulse wheel.he changing magnetic field induces an alternating voltage in the coil that can be measured. The frequencies and amplitudes of the alternating voltage are related to the wheel speed (Fig. 1) . Passive inductive sensors do not need a separate power supply from the control unit.
