Rapid Transit Vehicles

Transit operators using rail based guidance have a need to measure wheel movement on curves, wheel wear, and possibly offset height of linear displacement motors, etc. As wheels wear, or become eccentric; alignment and displacement on curved track quickly become more exaggerated. Knowledge of this information is important for both maintenance and safety reasons.

Presently, transit operations have no way to measure these small changes while the vehicle is in use, or even in motion. Many use hand measurement techniques after visible damage has occurred, or when the vehicle is in for regular service.

A simple task for the SPR-02 Single Point Sensor. With a sensor mounted either on the vehicle, or strategically placed on test sections of track, measurements can be taken while the cars are moving. This information is collected, then fed back to a computer. The data can be displayed to alert operations people when a car is not performing within required tolerance. Non contact sensors able to stand up to this type of use have not been available before.

SPR-02 sensors deliver instantaneous information, saving time and money for the Transit Authority.
