A device for 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, excitation winding, 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, signaling and measuring blocks. A Helmholtz coil is used as an open flat-topped magnetic conductor, and two flux gate meters placed at both sides of ferromagnetic construction at the center of the Helmholtz coil are used as a flux-sensitive transducer of magnetic field. |
