Abstract
The device comprises two excitation frames, which are installed at an angle one with respect to the other and rigidly connected to the receiving frame, to which a balancing unit, differential amplifiers and inputs for information of an electrical compensation unit are connected. The device is equipped with a commutator that determines successive connection to the generator, to the input of an excitation frame and of the control output of an electrical compensation unit and its output to the input of an amplifier and subsequently connection of the other excitation frame and control input of the other electric compensation unit and its output to the input of another amplifier. An information processing unit, recorders, an OR circuit and an alarm unit are connected to the amplifiers.
