Abstract
An overload protection device for a precision balance includes a measuring cell having a short travel distance, a parallel guide unit connected to a load receiving unit, and an auxiliary parallel guide unit whose guide members are connected to the load receiving unit, on the one hand, and to a weighing dish carrier member, on the other hand, wherein the guide members of the auxiliary parallel guide unit are pretensioned by at least one spring and form a rigid unit with the load receiving unit within the loading range of the balance. The auxiliary parallel guide unit includes an upper guide member and a lower guide member, wherein the two ends of the guide members of the auxiliary parallel guide unit on the side of the weighing dish are connected to each other by at least one guide bolt fastened to the upper guide member and the lower guide member. The guide bolt extends with play through a support plate which is fixedly connected to the load receiving unit of the measuring cell. The at least one spring is mounted between the upper guide member and the support plate.
