A device for the determination of mechanical stresses in ferromagnetic constructions includes a magneto-elastic sensor with open flat-topped magnetic conductor, excitation winding on the magnetic conductor, direct current power supply source, smoothing filter, time relay with contact group and two control circuits, measuring and signaling block connected to pair of contacts of time relay contact group, flux-sensitive transducer of magnetic field. A rod-shaped magnetic writing head is used as an open flat-topped magnetic conductor, and flux-gate meters are used as flux-sensitive transducer of magnetic field, those are placed along the side facets of the magnetic conductor of the rod magnetic writing head. |
