ROTATIONAL ANGLE DETECTION SYSTEM FOR DETECTING A ROTATIONAL ANGLE OF A ROTARY BRAKE DRIVE FOR A RAIL VEHICLE

A rotational angle detection system detects a rotational angle of a rotary brake drive for a rail vehicle and includes at least one sensor unit for detecting a rotational angle operatively connected to the rotary brake drive, and at least one main electronics path for transmitting control signals and/or sensor signals, wherein the at least one main electronics path can be operatively connected to the at least one sensor unit, wherein the at least one main electronics path includes at least one signal transmitter subdividing the main electronics path into a main electronics path section close to the sensor unit, viewed from the signal transmitter, and a main electronics path section remote from the sensor unit, viewed from the signal transmitter, and the at least one signal transmitter designed to electrically isolate the at least one sensor unit from the main electronics path section remote from the sensor unit.
