| 摘要 |
Device for determination of mechanical stresses in ferromagnetic constructions includes magnetic head, excitation winding, direct current power supply source, flux-sensitive transformer of magnetic field, smoothing filter, time relay with contact group and two control circuits, block for measurement and signaling connected to pair of contacts of contact group of time relay. Magnetic writing head is arranged as a vertebrate magnetic conductor in cylindrical form, and as flux-sensitive transformer of magnetic field a two-slot flux-sensitive reproduction head is used, that is connected to input of measurement and signaling block. |
