The device has a winding (6''), or at least a linear conductor (6'), coupled to a magnetic circuit (7) having an air gap (14). The winding or linear conductor is connected so that the current to be supplied passes through it. A magnetic field sensor (15) is arranged in the air gap and is connected to a measuring or control circuit (16), to produce an output signal representing the current by the current device. Preferably, the magnetic field sensor is a Hall effect sensor with a magneto-sensitive resistance or a flux gate component. |
