A device for determination of mechanical stresses in ferromagnetic constructions includes a magnetoelastic sensor with open magnetic conductor, excitation winding on the magnetic conductor, direct current power supply source, flux-sensitive transformer of magnetic field, smoothing filter connected with the output to the excitation windings, time relay, measuring and signaling block connected to pair of contacts of contact group of time relay. At that as magnetoelastic sensor two magnetic record heads are used, those are placed symmetrically at both sides of ferromagnetic construction. As flux sensitive transformer of magnetic field single-slot flux-sensitive reproduction heads are used, those are placed in inter-pole space of the magnetic conductors of magnetic record heads and are connected to the input of the measuring and signaling block. At that the open magnetic conductors of magnetic record heads are connected to the body with elastic elements.
