How BISON Weigh-in-Motion works

WEIGH IN MOTION BISON weighing sensors by fiber optic


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



The weigh sensor consist of bending plates made of stainles steel and equipped with fiber optic sensors connected by fiber optic cable to the datalogger.
