The study analyzed the methods for monitoring the state of the turbine unit shafting. In our research we developed our own method for monitoring the state of the shafting. As the parameters measured, we opted for vibration velocity and vibration displacement. The paper describes in detail the advantage of the chosen scheme with two sensors of vibration velocity and two sensors of vibration displacement. We also calculated the total error of the measuring channel. Finally, we proved the reasonability of applying the method for monitoring, based on the impact of the defect magnitude on the signal amplitude.
