Abstract
A direct current measuring device having at least one first magnetic sensor and at least one second magnetic sensor sensitive to a magnetic field generated by an electric current flowing in a conductor. The measuring device includes a processing unit connected to the magnetic sensors and generates an output signal dependent on measurement signals supplied by the magnetic sensors. The processing unit includes selection means supplying the output signal and is dependent, for weak electric currents, on the first measurement signals from a first magnetic sensor, and is dependent, for strong electric currents, on the second measurement signals from a second magnetic sensor.
