ABSTRACT:
A weighing apparatus, particularly a portable apparatus for weighing vehicles, comprising a resilient body formed of an elastomeric material in which is formed a closed cavity containing a liquid, said cavity being connected by a conduit to an indicator for indicating changes in volume of the cavity when the body suffers changes due to compression forces applied thereto by the member being weighed, said body having a resilient metal plate fixed to an upper surface thereof, a resilient metal load support plate mounted on the plate and a further resilient metal plate embedded in the body and spaced below the plate and to which reaction forces are applied during weighing.
