DF16 series axle-mounted sensor is a high-precision speed measuring and ranging equipment based on photoelectric effect. It can scan the inner and outer orbit of the grating through the photoelectric module and output square wave signals consistent with the grating grid. It can output up to 6 sets of square wave signals with different phases, which can be used to detect locomotive running direction, running speed, acceleration, idling and skidding.
It has the characteristics of high test precision, long service life, firmness, seismic resistance, high reliability, high pulse resolution, etc.
