A device for the determination of mechanical stresses in ferromagnetic constructions includes a magneto-elastic sensor with open magnetic conductor, excitation winding on magnetic conductor, direct current power supply source, flux-sensitive transducer of magnetic field, measuring and signaling block, smoothening filter, time relay with contact group, two control circuits. Additionally a magnetic biasing current source is used, this is connected with the output to the additional magnetic biasing windings, and with the input – to the additional contact group of time relay. |
