ABSTRACT:
A measuring device to measure a magnetic field having at least one measuring coil and at least one sensor to measure low-frequency magnetic fields, which measuring coil and which sensor have their planes of extension each positioned or positionable transverse to the flux direction of the magnetic field. The measuring coil and the sensor are connected to a signal processing device with which, depending on a first measurement signal provided by the measuring coil and a second measurement signal provided by the sensor, an output signal that essentially corresponds to the magnetic field can be generated. The measuring coil, the sensor, and the signal processing device are monolithically integrated into a semiconductor chip. The measuring coil may also be formed by means of traces of a printed circuit board on which the semiconductor chip that has the sensor and the signal processing device is located.
