A weigh module () includes a load cell (), a base plate (), a top plate (), a force-transmitting member () serving to transmit the weighing force from the top plate () to the load cell (), and movement-restricting means () which serve to limit the horizontal floating movement of the top plate () relative to the base plate () within a confined range of free play and to transmit lateral force components directly from the top plate () to the base plate (). One part of the movement-restricting means () has the form of a channel whose top edges () are rigidly connected to the top plate () and whose flat bottom extends parallel to the base plate () at a clear distance from the latter. The other part of the movement-restricting means () is a bolt whose shaft () is anchored in the base plate () and passes with all-around clearance through a passage () in the channel bottom (), and whose head () is larger than the passage () and arranged above the channel bottom () with a vertical clearance gap from the latter.

A hermetically sealed scale for use in a weighing scale. A scale of the present invention may include a load receiving plate and a bottom plate, between which is sandwiched a supporting rib structure that preferably includes a plurality of perimeter members that form sealed upright sides of the scale. The supporting rib structure, load receiving plate and bottom plate cooperate to form a substantially rigid and hermetically sealed sandwich structure. The load receiving plate may be joined to the supporting rib structure by perimeter welding or another bonding technique that permits the joining material to be subsequently shaped to form a smooth transition between the load receiving plate and the perimeter members of the scale.
