The paper considers the shortcomings of existing selsyn sensors, used in the monitoring and control system of winder for measuring the speed and depth of the cage. To eliminate the disadvantages of the existing control method of the specified motion parameters, two new parameter measurement methods - both suggest using non-contact measurement method based on ferromagnetic transformers, belonging to the group of electromagnetic transducers are proposed. The first method can be applied at the coal mining enterprises with the ground mounting of winder; the second method is versatile since it can be used in both ground, and tower (copra) mounting of the winder. These methods differ in the mounting place of the transducers. In addition, implementing the second method require using an additional structural element of the measuring channel of the system - belts with driving elements. Implementing the proposed mounting methods allows to improve the measurement accuracy of both speed, and depth of winder due to eliminating the influence of backlash on the measurement process, and increase the longevity of the measurement subsystem by using the non-contact method that will allow to extend the service life of transducers.References
