The invention relates to a measurement technique, and, in turn, to a means of measuring angular deformations, and can be used to measure angular deformations on objects of great extent from non-magnetic materials.

The purpose of the invention is to improve the accuracy of measuring the angular deformations of extended objects from non-magnetic materials at the expense of the Earth, which is achieved by introducing into the device two multipliers, an adder, an integrator and two additional one-component magnetic field strength meters, performing the main and additional meters with a measuring range, corresponding to the intensity of the magnetic field of the Earth, the connection of the second additional meter of tension with the first inputs of both multipliers, the main one, additional meters of intensity and output of the first multiplier with the inputs of the adder, output of the adder and the first additional meter of tension with the inputs of the second multiplier, and the output of the second multiplier with the integrator input, the output of which is connected to the second input of the first multiplier.

the main and the first and the second additional gauges 1-3 so that the sensitivity axis of the main gauge was directed perpendicular to this line and lay in a plane perpendicular to the axis of rotation of the object’s section chosen for the study, the axis of the first additional gauge 2 was parallel to the axis of the main gauge 1 and the axis of the second additional meter 3 was directed along the said line. At small angles of rotation of the axis of the h-sensitivity, the meter i is fire based on its initial position, the signal at the output of integrator 7 after the decay of transients in integrator 7 is proportional to the measured angular deformation of a given section of the object.
