A device for determination of mechanical stresses in ferromagnetic constructions includes two magnetic writing heads placed symmetrically at both sides of ferromagnetic construction, direct current power supply source, smoothening filter connected with its output to excitation windings, time relay, measuring and signaling block connected to a pair of contacts of contact group of time relay, the first and the second one-slot flux-sensitive reproduction heads placed in inter-pole space of magnetic conductors of magnetic writing heads and connected to the input of the measuring and signaling block. Magnetic writing heads are arranged in E-shaped form, and additionally the third and the fourth one-slot flux-sensitive reproduction heads are used, those are placed at the center of additional working gaps of magnetic writing heads. |
