Abstract
A device for determination of mechanical stresses in ferromagnetic structures includes a magneto-elastic sensor, magnetic writing head, direct current power supply source, flux-sensitive transformer of magnetic field, smoothening filter, time relay, contact group, two control circuits, measuring and signaling block, open magnetic circuit of the magnetic writing head, signal windings, through openings, modulator excitation windings, additional magnetic conductors with excitation winding, non-magnetic gaskets, two-slot flux-sensitive reading heads, additional input of the measuring and signaling block, source of alternating decaying current, third control circuit, magnetic biasing current source. The magnetic biasing current source is connected with the output to additional biasing windings, and with the input – to additional contact group of time relay.
