Development of Bullet Velocity Sensor Testing Device

A speed sensor parameter testing device is developed. The device can test emu speed sensor AG37 D, AG43 E characteristic parameters. According to the test requirements, it can test the output voltage, waveform and phase difference of speed sensor under different rotational speed and steering. The developed test device can be fast, accurate and reliable in testing the parameters of emu speed sensor, confirm whether the speed sensor is unqualified instantly according to the test result, so as to timely replace with new speed sensor, and ensure the real-time control of high-speed train running speed and position, give full play to the transportation efficiency, improve the train operation safety.
