How BISON weigh-in-motion works

WEIGH IN MOTION BISON -50-10 pesatura dinamica installazione sul casello autostradale


The Weigh In Motion (WIM) system BISON is composed of 2 stainless steel bending plates, installed flush with the road surface and can be placed on urban and suburban roads, motorways / highways, bridge and toll booths.



The bending plates are equipped with fiber optic sensors and connected by fiber optic cable to the datalogger.
