We have done the analysis of the two-phase operation of information-measuring system based on the sensor with moved magnetic field. A description of information-measuring system (IMS) to measure shaft beating on the basis of the electromagnetic system (EMS) moved magnetic field. For the analysis of the two-phase mode of operation used a computer model developed with the MatLab software. The main purpose of the analysis is to determine the operating conditions of the generator feeding EMC and transformation functions, so dependency, linking the output parameters - amplitude and initial phase of the output voltage of the bias, and the direction of displacement of the shaft relative to the stator EMC. The output voltage in the ideal case should be proportional to the displacement of the shaft. The linear dependence is maintained at the offset is 30 ... 40 percent of the length of the gap. This range of displacements and a work area sensor. An important role is played by the input impedance sine and cosine windings that are loaded two-phase generator. The magnitude of this resistance depends on the operating mode of the generator. The values of input resistance can be judged by the law of change of current windings and their initial phases. Analysis based on the mode of conclusions.
