Main benefits

Speed sensing is unaffected by wheel slip / slide
Less affected by changes in track bed substrate. No significant calibration shift compared to rival
No calibration is required as sensing is independent of wheel diameter
Robust design for mounting on the carbody and bogie
Virtually maintenance free
Availability >99.5%
Precise speed and distance readings are suitable of use with ETCS and ATO

HaslerRail offers a comprehensive range of products to satisfy the most demanding detection requirements and applications. The DOPRail 1000 incorporates two microwave radar modules to measure the vehicle speed over ground using the Doppler frequency shift effect. The DOPRail 1000 is based on monolithic microwave integrated circuit (MMIC) technology which is unsurpassed in terms of form factor and performance. With an optional inertial measuring unit (IMU) and intelligent signal evaluation integrated into the system, immunity from speed measurement deviations due to angular errors in mounting, pitch and roll is assured with DOPRail 1000.
