Abstract :
A sensor for measurement of magnetic field for long time is presented. It combines two sections: a mechanical part allows the measurement of the low frequency, while an inductive sensor provides the signal for high frequency analysis. After a description of the specification, its basic principle and architecture are presented. The performances of the sensor are discussed analyzing the response to a magnetic field step variation: the interest property is the long time extension of the sensor output without any drift. The frequency response of the sensor is also briefly analyzed
