Speed Wedge MKII Radar speed sensor
Product Overview
Speed measurement for in-door and off-highway vehicles, conveyor belts, material flow

Speed Wedge MKII is a speed sensor and active motion detector for moving objects, based on Radar Doppler technology. Speed Wedge MKII deploys a Radar Frontend with planar antennas continously emitting electromagnetic waves at 24 GHz. Due to the movement of the sensor or the object the frequency of the back-scattered waves are doppler shifted.
The forward speed of e.g. an indoor transportation vehicle, fork lift, conveyor belt or off-highway vehicle is measured contactless thus unsusceptible to wheel / drive slip, effective tyre circumference and sinking in of the tyre. For demanding applications Speed Wedge MKII is sealed and potted in a rugged encasing.
Speed Wedge MKII is available as a Series device.
