The article describes problems related to interference occurring in wheel sensors used in railway traffic control devices. The sources of interference affecting wheel sensors are discussed. Methods for measuring the interference immunity of wheel sensors are described. The results of tests conducted under laboratory conditions are presented.In the recent period, a phenomenon has emerged in the operation of railway traffic control devices regarding the impact of interference on wheel sensors used primarily in axle counters. Previously, these devices were considered resistant to the influence of electrical interference. In the initial period of using wheel sensors, only their resistance to the effects of fields caused by traction return current was checked. (…)
