ABSTRACT:
A device for converting the intensity of a magnetic or an electromagnetic field into an electric signal wherein movable elements are made as ferromagnetic plates rigidly fixed in supports so that their free ends overlap each other. Mounted on the deformation section in the immediate vicinity to the place where the ferromagnetic plate is fixed in its support is an element sensing the displacements of the free ends of the plates with respect to each other. The sensing element is made as at least one resistance strain gauge connected to a measuring circuit.
