A device for determination of mechanical stresses in ferromagnetic constructions includes a magneto-elastic sensor with magnetic record head, direct current power supply source, flux-sensitive transformer of magnetic field, smoothing filter, time relay with contact group and two control circuits, measuring and signaling block connected to a pair of contacts of time relay contact group. At that as a flux-sensitive transformer of magnetic field an open magnetic conductor of record magnetic head is used, each of pole tips of that one is provided with an additional winding and is arranged with through openings, there two additional excitation windings are placed, at that those additional windings are connected to the input of the measuring and signaling block. A source of alternating decay current is used, this is connected to excitation windings and to time relay with additional contact group and third control circuit.
