Abstract: A magnetometer that senses low level currents flowing in a conductor or wire includes two cores with excitation windings on each core that are connected in series but which are wound in opposite orientations. A periodic alternating current drives the windings. Since the windings are in series but oppositely wound, the current flowing through the windings will produce equal but opposite flux flows in the two cores. A sensing winding is wound around both cores to provide flux profiles. A digital processor analyzes a quiescent flux profile, which is generated when no sense current is flowing through the dual cores, and distorted flux profiles when sense currents are flowing through the dual cores to measure a sense current flowing through the dual cores.

Abstract: A device measures current magnitude in a conductor coupled to an electrical device and generates a signal comprising a series of pulses having a frequency. The frequency of the series of pulses is responsive to the magnitude of current measured. The device comprises a sensor magnetically linked with the conductor connected to the electrical device. The sensor produces an analog signal in response to the presence of a current within the conductor. A signal conditioner is located proximate to the sensor and is electrically coupled to the sensor so as to receive the analog signal. The signal conditioner produces, in response to the analog signal, a first signal representative of a magnitude of the current. A converter receives and converts the first signal into an output signal that comprises a series of pulses having a frequency. The frequency of the series of pulses is responsive to the magnitude of the current. All the sensor, the signal conditioner, and the converter are located in a single unitary package.
