A device for the determination of mechanical stresses in ferromagnetic constructions includes magnetic head, excitation winding, direct current power supply source, flux-sensitive transformer of magnetic field, smoothening filter, time relay with contact group and two control chains, measuring and signaling block connected to pair of contacts of the contact group of time relay. Magnetic writing head is arranged as an armored magnetic conductor in cylindrical form. A double-gap flux-sensitive reproducing head is used as a flux-sensitive converter of magnetic field, this is connected to the input of measuring and signaling block. Additionally the device includes a source of alternating decaying current connected to excitation winding and to time relay with additional contact group and third control circuit.
