Intercomp, headquartered in Minneapolis, is featuring fixed, in-ground sensors for weighing vehicles, here at the ITS World Congress. The company says the weighin- motion (WIM) strip sensors are the only higher accuracy option available that is currently manufactured in the United States.
Grouted into 3-inch (75mm) channels cut into the pavement, the strain gauge-based strip sensors detect wheel and axle weights, vehicle weights, and use axle spacing to determine vehicle classifications.
Operating over a wide range of conditions and temperatures, configurations of these sensors are employed in both low- and highspeed applications worldwide.
“Integration of our strip sensors into WIM systems has accelerated significantly over the past year,” said Jon Arnold, market specialist for Intercomp. Based on strain gauge technology, which is also used in Intercomp portable scales and highly accurate static scales, the sensors deliver performance from a technology that customers are familiar with.
“Approved for direct enforcement in China, used in high-speed data collection and screening for enforcement on multiple continents, and low-speed uses, such as border security and industrial applications in North America and Europe, the Intercomp strip sensor continues to provide customers a versatile and cost-effective WIM option,”
These sensors are used at speeds ranging from 2mph (3km/h) up to 80mph (130km/h). Installed in a vehicle lane within a single day with minimal civil works required, lane closures are kept to a minimum to incorporate and update WIM sites. Supplied within a complete system or integrated with existing electronics and software platforms, users have the flexibility to incorporate the WIM sensors at standalone sites or within current infrastructure.
