  • Measuring device with oscillation circuit including an exciting coil and tuned to a specific resonant frequency, for determining content of magnetizable substances in materials
    Patent number: 4835471
    Abstract: A measuring device for determining the content of magnetizable substances, particularly ferrite and martensite, in a sample, the device including an exciting coil which preferably has an iron core, for producing a magnetic field to be applied to the sample, and further including an evaluation circuit and a display device for displaying measurement quantities proportional to the content of magnetizable substances in the sample. To improve measurement accuracy, the exciting coil is a part of a tuned resonant oscillation circuit. The inductance of the exciting coil can be changed by the magnetic field induced in the sample as a result of the applied magnetic field, whereby the change in inductance results in a change in the resonant frequency of the oscillation circuit.
