ABSTRACT:
Detection of a zero speed or moving railway vehicle wheel or other metallic object is accomplished by providing a balanced E-core inductive detector. An exciter coil on the center leg of the E-core inductively couples a pair of sensor coils connected in series opposition on the outside legs of the E-core. A voltage detector responsive to unbalancing of the E-core magnetic field by a train wheel or other metallic object is connected to the output of the sensor coils. A zero speed wheel located at the center of the magnetic field is detected by using the output of one of the sensor coils compared with the phase shifted and amplitude adjusted exciter signal. Speed and direction of travel are also determined by monitoring wheel detection output sequencing and timing.
