Counterweight
To prevent the external sensor causing an imbalance on the wheel, a counterweight is mounted on the
opposite side.
Axles with twin tires do not need a counterweight. In this case, the external sensor of one wheel serves
as counterweight for the external sensor of the other wheel. The external sensors are opposite each
other.
