Why weighment differ with speed in an inmotion weigh bridge?

Answer 1

Because the truck moves at different speeds, the sensors get uneven pressure for a split second, which changes the reading. Slow, steady speed gives the most accurate result. That’s why industries prefer stable, well-tuned systems like Essae Digitronics for consistent in-motion weighing.

Answer 2

In motion weighbridges rests over load cells /transducers.when locomotive moves over it its cells gets pressed resulting in voltage production which is pre calibrated to weight.However if the loco moves within a pre specifed speed(5-8 km/hr)the load cells compression and resulting vpltage production remains constant .but if the loco moves in a higher speed then sometimes the cells can not pick them at all.At low loco speed cells gives erroneous results dot to its long compression period .hence operators are advised to run the loco within its permissible speed limit.
