ABSTRACT:
A load weighing apparatus for weighing a weight of a load on a vehicle comprises an intervening element provided between a body frame and a suspension for transmitting the weight of the load to the suspension from the body frame. The intervening element is formed of a magnetic material and has a plurality of bore sections. An excitation winding is wound about the intervening element through ones of the bore sections, while a measurement winding is wound about the intervening element through the remaining bore sections. An electric power source for applying voltage is connected to the excitation winding. A measuring unit for measuring voltage across the measurement winding is connected thereto.
