Description
The Path and Speed Sensor (DPS-I) is designed to convert the rotation angle of the wheelset axle into discrete electrical signals used in measuring systems that monitor the direction of movement.
Using information from the DPS-I, locomotive measuring systems control the direction of movement, traveled distance, speed, and acceleration of railway rolling stock at wheel angular speeds up to 2123 rpm (corresponding to 250 km/h).
The DPS-I is mounted on a locomotive by attaching the moving part to the end surface of the wheelset and the stationary part to the axlebox housing, with each part fixed using four bolts.
The DPS-I undergoes pilot tests on the Sverdlovsk Railway. After completion, it will enter serial production.
