Abstract
The invention relates to a device for measuring the mass of a magnetic material () present in an analysis medium, that comprises: a modulator () of the phase of a high-frequency and/or low-frequency component of a magnetic field for exciting the analysis medium with a modulation signal having a value that is modified by a frequency f; and a demodulator () capable of demodulating the amplitude of an amplitude signal, measured in response to the excitation field, from the modulation signal, wherein said demodulator is connected to the output of a filter () and to the input of an estimation unit ().
