The Speed Sensor operate according to Hall Effect principle measuring principle. The Speed Sensor is for the measurement of Locomotive Wheel Speed and is powered by the power supply from Traction Converter. The speed sensor deigned to measure the speed close to Zero. Speed measured with detecting movements of ferromagnetic tooth wheel. Designed to withstand Traction Vibration and shock as per latest railway standards.
