HaslerRail developed the optical and contact-free CORRail 2000 speed sensor to deliver track-bed independent direct measurement of a rail vehicle’s speed and direction. The technology behind the CORRail 2000 is known as Spatial Filtering Velocimetry and is neither affected by slip & slide effects nor by the wearing of the wheels as pulse generators are.
Using the railhead as reference makes the CORRail 2000 speed sensor outperforming microwave based sensors (= no calibration shift due to changing surfaces on the track-bed). By scanning the railhead’s microstructure with its high resolution the CORRail 2000 speed sensor’s accuracy and precision are unrivalled in its class.
The patented splash guard assures reliable results even under the harshest environmental conditions. The CORRail 2000 is proven in use: Availabilities of >99.5% are reached even the CORRail 2000 is being in operation for months.
The CORRail 2000 is designed to deliver an objective measurement of longitudinal dynamics for the following applications:
– Signaling Systems e.g. ETCS, ATO
– Propulsion Systems: True speed over ground for wheel slip slide control
– Measurement of braking distance: Navigation/Positioning
