Product ID: DRS05
The DEUTA DRS05/3 is a two-channel contactless radar speed and distance sensor operating on the Doppler principle, equipped with a dual antenna system and an integrated acceleration sensor. The device eliminates wheel slip errors, providing exceptional odometry accuracy across a speed range from 0.2 km/h to 600 km/h.
Product features:
Minimum life cycle costs (LCC) due to wear-free operation and low maintenance requirements
Forward/backward movement recognition
Speed measurement unaffected by wheel slip and slide
Suitable for ETCS, CBTC, and traction control applications• Product description
The sensors operate contactless and measure speed and distance over the ground by deploying the Doppler principle with a dual antenna system. The integrated digital signal processor performs sophisticated evaluation algorithms in the device. Special two-channel algorithms reduce the calibration-shift effect, thus providing high accuracy even with changing surfaces.
The integrated acceleration sensor supports speed measurement and minimises dynamic deviations. Short unavailability can be bridged, while interference signals at a standstill are suppressed. Radar sensors of the DRS05 type can be used worldwide, with declarations of conformity available for Europe, U.K., Canada, USA, Japan, and Australia.
