Device for determination of mechanical stresses in ferromagnetic constructions that includes magneto-elastic indicator with magnetic writing head, direct current power supply source, flux-sensitive transformer of magnetic field, smoothing filter, time relay with contact group and two control circuits, block of measurement and signaling connected to pair of contacts of contact group of time relay, as flux-sensitive transformer of magnetic field open magnetic conductor of magnetic writing head is used, each of pole pits of that one is provided with additional winding and is arranged with through openings, there two additional excitation windings are placed in each, at that those additional windings are connected to input of block of registration and signaling. At both sides of main magnetic conductor two additional magnetic conductors are placed, with winding, those are fixed to it through non-magnetic pads, at that windings of additional magnetic conductors are connected as reversed with respect to excitation winding of main magnetic conductor.
