PreView Sentry has been a world-leader in close proximity collision mitigation radars for many years now. With on-ground consultation with contractors and mining customers, a limitation of certain applications were identified.

During installation of a large haul truck, it was identified that with PreView Sentry’s patented 150° beam pattern, the inner rear wheels of the truck were within the radar’s detection zone – therefore causing false detections. PreView Xtreme radar remained the only solution for haul trucks due to the narrower beam pattern.

Enter the PreView Sentry®X
Using the Sentry platform, PRECO has created a product with a narrower field of view designed to support all the same applications/solutions as the original PreView Xtreme radar.

The Sentry®X measures radial range, speed and angle, reflectivity, and other parameters of multiple stationary and moving targets simultaneously – making Sentry X one of the world’s leading close proximity collision mitigation solutions.

PreView Sentry®X Features & Benefits
