Product ID: DEUTA DRS05/3S1
The DEUTA DRS05/3S1 is a contactless two-channel Doppler speed sensor equipped with an integrated protective hood to resist stone impacts and harsh winter conditions. Featuring a dual antenna array and an acceleration sensor, it ensures continuous speed measurements from 0.2 to 600 km/h for high-speed rail and metro operations.
Product features:
Integrated protective cover against impact of stones
Suitable for ETCS, CBTC, high-speed trains, and metro vehicles
High availability under severe winter conditions
Minimum life cycle costs (LCC) due to wear-free non-contact operation• Product description
At the DRS05/3S1, an integrated protective hood prolongs the durability of the radar sensors when they are hit by stones and extends availability in winter conditions. Such housing is specially recommended for high-speed trains and metro vehicles. Under winter conditions, the integrated protective hood together with a redundancy concept basing on Doppler signal amplitudes and taking into account a spectral evaluation assures high availability.
The DRS05/3S1 radar sensors measure speed and distance contactless and slip-free using the Doppler principle. The integrated acceleration sensor supports speed measurement and minimises dynamic deviations while suppressing interference signals at a standstill. In combination with the DEUTA SmaRT App, inclination measurement and calibration become effortless.
