Strain gauge technology is used in static weighing for direct weight enforcement and is accepted as the most accurate and reliable means to weigh a vehicles. Intercom’s strips sensors integrate the same strain gauge technology incorporated into a compact strip for accurate WIM application. Offering the lowest cost of ownership of any precision WIM sensor, the price, durability, and longevity of Intercomp sensors deliver performance to rely on
