A housing for receiving a load cell comprises a base plate for receiving a load cell, a weight dispersing means for use with the load cell so that a load is balanced, an enclosure which surrounds the load cell therein from the base plate to the weight dispersing means, and a receiving portion for receiving the load. The enclosure has an outer wall which surrounds the cell, the outer wall extends generally vertically from the base plate. The enclosure has an outer wall which surrounds the cell, the outer wall extends generally vertically from the bas e plate providing an area between the base plate and the weight dispersing means for enclosing the load cell therein, a cap is attached to a top end of the outer wall and has an opening located directly above the weight dispersing means which cap allows a top portion of the weight dispersing means to protrude from the enclosure so that the receiving portion can be attached thereto and wherein the cap ha s a guiding arrangement for limiting the movement of the weight dispersing means . The weight dispersing means has a first receptacle mounted on the load cell, the receptacle is cylindrical in shape and has a vertical axis, a first side of the receptacle faces downward engaging the load cell, a second side opposite the first side faces upwardly, the second side has a concave centre and an outer ledge located about the axis, wherein a second receptacle being cylindrical in shape has a secon d vertical axis which extends coaxially with the first vertical axis of the first receptacle, a first side of the second receptacle faces upwardly and a second side faces downward and has a concave center and an outer ledge located about the axis, and wherein a sphere is located between the each concave centers such that the centre 15 of the sphere is substantially located on the vertical axis, the sphere is arranged to move between each receptacle within each concave such that as a load is plac ed on the receiving portion downward force is applied to the sphere which balances the load within the enclosure by moving within each concave secured by each oute r ledge.
