A device for determination of mechanical stresses in ferromagnetic constructions comprises a magnetic head, excitation winding, power supply direct voltage source, a flux-sensitive transducer of magnetic field, smoothing filter, time relay with contact group and two control circuits, measurement and signaling unit connected to a pair of contacts of a contact group of time relay, magnetic record head is arranged as an vertebrate magnetic conductor in cylindrical form, and as a flux-sensitive transducer of magnetic field a two-slot flux-sensitive reproduction head is used, this is connected to the input of the measuring and signaling unit. A source of alternating decaying current is placed, this is connected with the output to the additional excitation winding, and with the input – to additional contact group of time relay.
