ABSTRACT:
A distance and temperature sensing unit is used on paving vehicles. The unit has a first set of range sensors of a first diameter and a second set of range sensors of a second diameter. The unit calculates a weighted average distance to a road surface based on ranges measured by the multiple sensors. The unit also has a temperature sensor on a temperature bar. The bar is affixed to the unit by a flexible connection preventing break-off when the bar encounters obstacles, like the road surface, while the paving vehicle is moving.
