A weighing module with a housing surrounding a weighing cell on all sides has a vertically movable force transfer member designed to be connected to a load-receiving device. The force transfer member extends through a passage opening of a housing wall and is rigidly connected to a vertically movable part of the weighing cell. The weighing module includes a dust-removing device which further includes a means for generating a gas flow directed away from the movable part of the scale for the purpose of preventing an accumulation of dust between the stationary housing and the vertically movable force transfer member.

Weighing module with a dust removing device

A baffle seal at the opening () for the load-transmitting member () in a balance housing () has at least one sleeve-shaped ring element (), fastener means () attached to the housing () and serving to hold the sleeve-shaped ring element in a stationary working position surrounding the opening, and a cover cap () with at least one sleeve-shaped ring () that is axially movable relative to the sleeve-shaped ring element. The ring element is releasable so that it can be separated from the balance without dismantling other parts.
